Odroid C2 Temporary run images from USB

[balbes150]

Tested on Odroid C2 system startup from the USB stick (via script s905_autoscript, I prefer to run existing images without any modification). If add the script to the boot.ini a few lines, you can run images from a USB drive. This can be useful if there is on eMMC or on a SD card configured with the system and felt the need to run temporarily another system (without overwriting the existing SD\eMMC media). For example, for temporary checks new images, when unknown , to like this system or not, or for testing settings\software-that-be not to destroy the already set up working system. Process start automatically if the connected USB drive and it has a script that starts the system with the USB. When no USB media run regular system with SD\eMMC.

For owners Odroid C2 , which have a fine-tuned system (any) on the SD card or eMMC module and want to try option Armbian with kernel 4.11+ (MATE\XFCE or server) without risk to the existing system. There is the option of running the system from USB stick (available at SD or eMMC system remains unchanged).

1. To download the correct image to the link

2. Unpack

3. To record on a USB flash drive (the size of the flash drive of 4 GB, the parameters of any).

4. Download and add on the USB flash drive file dtb for the Odroid (file in the place where site the images)

5. Rename the recorded file dtb to the "dtb.img"

 

meson-gxbb-odroidc2.dtb

 

6. To add to the run settings file u-boot (for SD or eMMC media boot.ini) the second line in this string.

ODROIDC2-UBOOT-CONFIG

 

# Add run USB script s905_autoscript

if usb start; then setenv dtb_mem_addr "0x1000000"; if fatload usb 0 1020000 s905_autoscript; then autoscr 1020000; fi; fi;

---------------------------------------------------

 

7. Off Odroid C2 to connect the SD \ eMMC media with the main system and USB flash drive with the test system

8. To turn the power on. If done correctly, and 5-7 minutes on the screen you should see a standard login prompt for initial setup Armbian. When you turn on Odroid C2 without the Usb stick will automatically start a regular system. If desired, you can modify the line to boot.ini under run multiple systems with USB and SD\eMMC media. For example, to have the main system on the eMMC and run the same test with the SD card.

 

 

 

p.s. During the test, I found a periodic problem with the dtb file on the website. If the dtb file from the website will be error, you need to try to use the dtb from the image from the catalog dtb. He's working with wired network (you can connect via SSH), but there is no video output on the monitor.

As it turned out, with Odroid C2 works perfectly dtb file meson-gxbb-p200-lan (it's on the website, along with files of images). This dtb file works USB , wired network and video output (all three essential ingredients for successful start and run the desktop version).
