Revision as of 09:02, 4 September 2016

Variscite provides a recovery SD card image that can be used to install the pre-built U-Boot, Linux kernel and the file system into the internal storage/s of the SOM.

Preparing a recovery SD card

Download mx6-som-recovery-sd.vXX.img.gz (latest) which is available on Variscite's FTP: ftp://customerv:Variscite1@ftp.variscite.com/VAR-SOM-MX6/Software/
Plug-in the SD card to your Linux HOST PC, run dmesg and see which device is added (i.e. /dev/sdX or /dev/mmcblkX)

$ gunzip mx6-som-recovery-sd.vXX.img.gz
$ sudo umount /dev/sdX*
$ sudo dd if=mx6-som-recovery-sd.vXX.img of=/dev/sdX bs=1M

(Replace /dev/sdX with your actual device)

Recover NAND Flash/eMMC

Power-off the board.
Insert the SD card into the SD card slot of the carrier board (DVK)
Make sure the BOOT SELECT DIP switches are set to SD card: Setting the BOOT SELECT DIP switches
Power up the board - it will boot into Linux from the SD card

Flash from GUI

Touch/Click on the appropriate icon:

Install Yocto NAND flash: Flash Yocto to NAND flash
Install Yocto eMMC: Flash Yocto to eMMC

Flash from command line

Login as root (no password)
From Linux command line, type one of flash options

$ install_yocto.sh	- Flash Yocto into eMMC or NAND Flash (Follow instructions)
