Improved Win32DiskImager

Posted on by admin

We already posted “How to make a bootable SD/microSD/eMMC” in this link.  http://www.hardkernel.com/?b130
But few people have met the problem of flashing SD with ‘win32DiskImager’ or ‘dd’ utility.

Those utilities read data from an OS image file and write it to storage media.
But USB host in your PC, USB memory card reader or SD card itself may have problem to perform the secure and stable image copy.

Because of those root causes, the OS image can’t be copied properly or corrupted in SD card.
So I decided to add a feature of verification of written image on the win32DiskImager Ver 0.6.

Basic flow of writing/verification is here!
1. Read 512KB from OS image file to buffer-a.
2. Write 512KB(buffer-a) to SD card.
3. Read 512KB from SD card to buffer-b.
4. Compare buffer-a with buffer-b. If they are different, stop the loop.
5. Increase pointer and goto #1 by end-of-file.

You can download the modified Win32DiskImage binaries in this link. It is working with WinXP/Win7.
http://dn.odroid.com/DiskImager_ODROID/win32diskimager2-binary.zip

Modified source code is here. You need the MinGW and Qt 4.8.4 SDK to compile it.
http://dn.odroid.com/DiskImager_ODROID/win32diskimager2-source_ODROID.zip

Note
1. The writing time is almost twice of the original version because of verification process.
2. The file name/path should not contain the 2-byte characters like Korean,Chinese,Japanese and so on.

Note:
1. We are using the Altium-Designer to develop the schematics and PCB.
2. There is no copyright issue on our schematics. It is a sort of open hardware. It is possible to clone the ODROID-U2/U with your risk.
3. We don’t supply/sell any PCB design file or Gerber file. Please don’t ask about it.
4. When we update the schematics in future, we will share it.

How to handle the ODROID-U/U2

Posted on by admin

ODROID-U / U2 board is half cased with heatsink. There are three screws to hold the board with heatsink.

There are three nuts mounted on the PCB.

The board is supported by three small nuts to heatsink. Please be careful especially when you connect cables. You must have to hold the board not the heasink when you connect cables. Otherwise, the nuts might be damaged and that could cause the board damage.

Case 1 : USB connector

Case 2 : Ethernet Cable

Case 3 : HDMI Cable and Micro USB Cable

More tips! for cooling fan. The red line is outside.

Ubuntu ARM on ODROID-X2/X

Posted on by admin

We have made two major progresses of development on ARM Ubuntu for ODROID-X/X2.

1. Dual head display feature
HDMI monitor of 1920×1080 resolution is working as a primary display.
LCD module of 1366×768 resolution is working as a secondary display. ( LCD Module kit information )
You can move the mouse cursor and window between the primary and secondary display.

2. eMMC device driver in Kernel 3.6.x
Now we can access the eMMC flash storage in Ubuntu/Linux.
mdrjr has committed his great port of eMMC driver into our github. Many thanks to him.
With this update, the OS booting time as well as overall performance is significantly improved.
We will release a brief guide for installation of Ubuntu on eMMC soon.

Enjoy this video and feel the boosted performance by eMMC and dual head display.

Here is our X11 configuration file for dual head display on ARM Ubuntu.

ODROID-X/X2 : History of PCB revision.

Posted on by admin

We have 4 revisions of ODROID-X/X2 base board up to now.

Rev 0.1  2012.6.20
First trial. Only for internal test purpose. We didn’t sell this revision.
We must cut some signal lines and added wires to make it work.
ODROID-X DC Jack wass identical to LCD board DC Jack.
But ODROID-X needs 5Volt and LCD board needs 9Volt.
So we killed many boards with wrong power supply due to confusion.

Rev 0.2  2012.7.04
Only for internal test purpose too. We didn’t sell this revision.
Changed DC Jack from 5.5mm to 2.1mm to prevent wrong plug/voltage.
Added more understanable texts on silk-screen printing.
Changed HDMI resolution setting jumper from 3pin to 2pin
Added SD/eMMC booting jumper instead resister soldering.

Rev 0.3  2012.7.13
This revision is used in the first mass production.
Slightly changed 5Volt input path.
Rubber foot added.
Heatsik added.
Shipped from end of July.

Rev 0.4  2012.8.08
3.3Volt Buck DCDC converter(U7) was changed from Ricoh RP505K331 to Torex XCL205B333.
This change was caused by market situation simply. There is no negative side effect.
We couldn’t purchase RP505K331 temporarily and we decided to replace it with XCL205B333 with minor modification of PCB.
Shipped from early September. Rev 0.3 and Rev 0.4 can be mixed for a while.

Download attached file which contains below schematics in PDF format.
– ODROID-X base board Rev 0.3
– ODROID-X base board Rev 0.4
– ODROID-X LCD board
– ODROID-X USB-UART board
– ODROID-X/Q eMMC board

Rev 0.5  2013.4.08
– Audio input circuit is modified for optimized mono-microphone input.
– Auto-power-on signal is hard-wired.
– HDMI reverse current blocking circuit is implemented.
– PCB silk change (ODROID-X to ODROID-X2+)
Shipped from early April 2013. Rev 0.5 and Rev 0.4 can be mixed for a while.

Rev 0.6 2014.4.18
http://dn.odroid.com/4412/Hardware/ODROID-X_BASE_Rev_06.pdf
– Added U1 AP2331 to completely block the HDMI leakage current.

Schematics of Exynos 4412 CPU Module will be available by email request to odroid@hardkernel.com with ODROID-X2 serial number which is printed on PCB. Please be noted that the serial number can be registered only once.

We do not have any plan to release schematics with other format at this moment.

Welcome to Linaro 12.07 (GNU/Linux 3.6.0-rc1 armv7l)

* Documentation:  https://wiki.linaro.org/

106 packages can be updated.
20 updates are security updates.

root@linaro-ubuntu-desktop:~#

 

Yes!
There are many points to reduce the booting time.
Let’s find how to improve it!

We’ve implemented and tested below features.
– Linux Kernel 3.6-rc1 with gcc 4.7.1 Linaro toolchain
– SMP driven Quad-Core processing
– PMIC device driver
– USB 2.0 High-speed Host driver for Exynos-4412 HSIC interface
– Ethernet + USB Hub device driver
– LCD display driver
– HDMI display driver (Very early version and it may have HDMI 1.4a compatibility issues with some monitors)

Known issues.
– Audio codec driver is not ported (We will implement this within couple of weeks)
– eMMC device driver is not ported (We will implement this within couple of weeks)
– Clock control driver is not ported (We will change the default clock from 1Ghz to 1.5Ghz soon)
– 3D HW-GPU X11 driver is not ready (This may need couple of months)
– Power-off  (Power off function of Ubuntu GUI is not working. There is no way to power off except for unplugging DC plug. OTL)
– WiFi module is not working with Ubuntu GUI. (Command line of Wireless-tools may work)
– Many other issues

This WiKi describes how to build it and how to use pre-built image for SD-card.
http://dev.odroid.com/projects/odroid-xq/#s-3.2

You can download the pre-built images from this bit-torrent.
bit-torrent Ubuntu-ODROIDX
There are two different pre-built images.
#1. Image file for LCD display
#2. Image file for HDMI display

Please note this version doesn’t support eMMC. So you must plug JP2-jumper.
If your HDMI monitor supports only 720p, you must unplug JP1-jumper. If your monitor supports 1080p, plug JP1-jumper.
We need to implement automatic detection function in future.

Refer below picture to know where is JP1 & JP2.

SD Card setup for ODROID-X

Posted on by admin

To boot the ODROID-X/X2/U/U2, you need an SD card or eMMC module installed with a bootloader and a suitable Operating System.

Some ODROID kits will come with a ready-to-go card, but if you didn’t purchase one you will need to prepare your own:

Official images are available in this link.

Warning! When you write the ODROID image to your SD card you will lose all data that was on the card.

 

Copying the image to an SD Card on Windows

  1. Download a zipped image from this link or other mirrors
  2. Extract the image file .img or .odt from the zip file.
  3. Insert the SD card into your SD card reader and check what drive letter it was assigned. You can easily see the drive letter (for example G:) by looking in the left column of Windows Explorer. If the card is not new, you should format it; otherwise Win32DiskImager may hang.
  4. Download the Win32DiskImager utility. The download links are on the right hand side of the page, you want the binary zip.
  5. Extract the zip file and run the Win32DiskImager utility. You may need to run the utility as Administrator.
  6. Select the *.img image file you extracted earlier
  7. Select the drive letter of the SD card in the device box. Be careful to select the correct drive; if you get the wrong one you can destroy your computer’s hard disk!
  8. Click Write and wait for the write to complete.
  9. Exit the imager and eject the SD card.
  10. Insert the card in the ODROID, power it on, and it should boot up. Have fun!

 

Copying an image to the SD Card in Linux (command line)

Please note that the use of the “dd” tool can overwrite any partition of your machine. If you specify the wrong device in the instructions below you could delete your primary Linux partition. Please be careful.

  1. Download a zipped image from this link or other mirrors
  2. Extract the image, with (just an example)
    • unzip ~/OdroidX_image_31-Jul-2012.zip
  3. Run df -h to see what devices are currently mounted
  4. If your computer has a slot for SD cards, insert the card. If not, insert the card into an SD card reader, then connect the reader to your computer.
  5. Run df -h again. The device that wasn’t there last time is your SD card. The left column gives the device name of your SD card. It will be listed as something like “/dev/mmcblk0p1” or “/dev/sdd1”. The last part (“p1” or “1” respectively) is the partition number, but you want to write to the whole SD card, not just one partition, so you need to remove that part from the name (getting for example “/dev/mmcblk0” or “/dev/sdd”) as the device for the whole SD card. Note that the SD card can show up more than once in the output of df: in fact it will if you have previously written a ODROID image to this SD card, because the ODROID SD images have more than one partition.
  6. Now that you’ve noted what the device name is, you need to unmount it so that files can’t be read or written to the SD card while you are copying over the SD image. So run the command below, replacing “/dev/sdd1” with whatever your SD card’s device name is (including the partition number)
    • umount /dev/sdd1
    • Note that if you are not logged in as root you will need to prefix this with sudo
    • If your SD card shows up more than once in the output of df due to having multiple partitions on the SD card, you should unmount all of these partitions.
  7. In the terminal write the image to the card with this command, making sure you replace the input file if= argument with the path to your .img file, and the “/dev/sdd” in the output file of= argument with the right device name (this is very important: you will lose all data on the hard drive on your computer if you get the wrong device name). Make sure the device name is the name of the whole SD card as described above, not just a partition of it (for example, sdd, not sdds1 or sddp1, or mmcblk0 not mmcblk0p1)
    • dd bs=1M if=ODROID-X_31_07_2012.img of=/dev/sdd
    • Note that if you are not logged in as root you will need to prefix this with sudo
    • The dd command does not give any information of its progress and so may appear to have frozen. It could take more than five minutes to finish writing to the card. If your card reader has an LED it may blink during the write process, or you can run pkill -USR1 -n -x dd in another terminal (prefixed with sudo if you are not logged in as root).
  8. As root run the command sync or if a normal user run sudo sync (this will ensure the write cache is flushed and that it is safe to unmount your SD card)
  9. Remove SD card from card reader, insert it in the ODROID, and have fun

Copying an image to the SD Card in Linux (graphical interface)

If you are using Ubuntu and hesitate to use the terminal, you can use the ImageWriter tool (nice graphical user interface) to write the .img file to the SD card.

  1. Download a zipped image from this link or other mirrors
  2. Right click the zip file and select “Extract here”
    • ATTENTION: As of this writing (15 June 2012), there is a bug in the ImageWriter program that causes it to fail if the filename of the image file or its path (i.e. all the names of any parent folders that you extract the image file into) contain any space characters. Before going any further, ensure that neither the file name of the image you’re using or the path contain any spaces (or other odd characters, for that matter). A bug has been opened for this issue: https://bugs.launchpad.net/usb-imagewriter/+bug/1013834 Once the issue is fixed, edit this page to advise people to use an updated/patched version of ImageWriter.
  3. Insert the SD card into your computer or connect the SD card reader with the SD card inside
  4. Install the ImageWriter tool from the Ubuntu Software Center
  5. Launch the ImageWriter tool (it needs your administrative password)
  6. Select the image file (example ODROID-X_31_07_2012.img) to be written to the SD card (note: because you started ImageWriter as administrator the starting point when selecting the image file is the administrator’s home folder so you need to change to your own home folder to select the image file)
  7. Select the target device to write the image to (your device will be something like “/dev/mmcblk0” or “/dev/sdc”)
  8. Click the “Write to device” button
  9. Wait for the process to finish and then insert the SD card in the ODROID

Manually resizing the SD card partitions (Optional)

The SD card image is sized for a 8GB card. The Fedora Remix will automatically resize the partitions on the card during the first boot. The Debian version won’t, so you’ll have to do it manually. It’s much easier if you do this on another machine, as the SD card can’t be mounted when you do this.

Look here for instructions.

Please note most of those instructions came from famouse RPi WiKi.

USB-UART Module Kit

Posted on by admin

There is a system console port in all of ODROID series to monitor the low-level information of target system.
This is very useful and important tool for platform software development.

The system console port uses UART(Universal asynchronous receiver/transmitter) of CPU for communication between your host PC and target board.
Protocol is 115200bps / no-parity / 8bit / 1-stop-bit / No-flowcontrol as usual.
You can use any tty terminal software such puTTY, minicom or hyperTerminal in your host PC.

The UART of CPU has simple 2 signals Tx and Rx with a ground level for communication.
Please note most of new comming mobile processors have 1.8V of IO voltage to minimize power consumption.

In traditional design, there should be a RS-232C level converter MAX232 or MAX3232 or MAX3218 on board.
Addtionally your Host PC must have a RS-232C port.
Note that all of modern PC / Laptop have no built-in RS-232C port you have to buy a USB-RS232 converter.
So this solution is expensive, uncomfortable and bigger footprint.

Fortunately, there are many IC makers have introduced USB-UART bridge ICs.

To meet the low voltage interface specification. we chose the CP2104 USB-UART bridge IC from the Silicon Labs.
You can find the datasheet of CP2104 and its drivers from this link.
http://www.silabs.com/products/interface/usbtouart/Pages/usb-to-uart-bridge.aspx

CP2104 has internal oscillator, LDO, Tx/Rx indicating LED drivers and 1.8Volt IO with reasonable price in 4mmx4mm package.


USB-UART Module kit contains below 3 items.

– Micro-USB cable
– USB-UART board with CP2104
– 4pin wire harness to connect to ODROID-X

 

Let’s look into USB-UART board.
You can find Micro-USB connector, 4-pin Wire-connector, USB-UART bridge IC CP2104 and 3 LED inticator on top side.
D1 is Tx LED, D2 is Rx LED and D3 is power indicator. Note this board is powered by USB of host PC.
On bottom side, there are some passive devices and USB signal conditioner of L1.

Place the 4pin wire harness between USB-UART board and your ODROID-X/X2/U2/U3/C1/XU3/XU as below picture.
And place the Micro-USB cable between your host PC and USB-UART board.

You can download proper device drivers for your host PC.
Click “Tools” tab to get drivers for Windows, Mac and Linux in this link.
http://www.silabs.com/products/interface/usbtouart/Pages/usb-to-uart-bridge.aspx

I want to let you know some information of CP2104 device driver for your host Linux PC.
If your host Linux PC runs Kernel 3.2 or higher, the CP2104 works without any addtional installation/compilation.
Note Ubuntu 12.04 is based on Kernel 3.2.

This is a USB-UART board for ODROID-Q model which also has CP2104.
We call it “Debug board” from time to time.
