DART-6UL - Yocto recovery SD card
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 of the SOM.
Download the recovery SD card image
Download mx6ul-dart-recovery-sd.vXX.img.gz (latest) from Variscite's FTP server: sftp://customerv@ftp.variscite.com/Public/DART-6UL/Software/yocto/legacy-images
For more information about Variscite's FTP server, see: https://variwiki.com/index.php?title=FTP
Write the image to an SD card
Using a Linux based host
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 mx6ul-dart-recovery-sd.vXX.img.gz $ sudo umount /dev/sdX* $ sudo dd if=mx6ul-dart-recovery-sd.vXX.img of=/dev/sdX bs=1M (Replace /dev/sdX with your actual device)
Using a Windows based host
Download Win32 Disk Imager from: https://sourceforge.net/projects/win32diskimager/, install and run it.
Select the image file, and the SD card device - double check that the device is correct to avoid accidentally overwriting a different device.
Click on "Write".
No need to format the SD card before writing the image to it.
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 DIP switches are set to SD card: Setting the Boot 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, WiFi: Flash Yocto with WiFi support to NAND flash
- Install Yocto NAND, SD card: Flash Yocto with SD card support to NAND flash
- Install Yocto eMMC (SD/WiFi) : Flash Yocto to eMMC (installs both SD card and WiFi dtbs to the BOOT partition and let U-Boot select between them at boot time)
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)
