How to write image to VisionSOM-6ULL eMMC using UUU tool on Windows


Prerequisites

  • PC with Microsoft Windows 10 64-bit OS
  • A complete package with NXP UUU application
  • Prepared SD card image or eMMC memory dump generated by yourself (for example called: sdcard.img)

Information

  • SOMLABS solution is based on NXP UUU tool, with some extensions added on top of it to easly handle SOMLABS boards.
  • You can use different file names than default (vsom-6ull-fb.bin, rootfs.ubi, sdcard.img) - these names are just examples.
  • Please note also, that file can be located in any directory - you need to specify complete file path then.
  • If you are using VisionSOM module with i.MX6UL processor, please change in commands given below '6ull' to '6ul'
  • A file named "vsom-6ull-fb.bin" (included in the above package) is a u-boot file, which is used only while flashing eMMC/SD card with UUU application. The user u-boot located inside sdcard.img remains unchanged.

Preparing

For programming a memory of VisionSOM-6ULL, switch boot selector to mode: SERIAL.

BOOTx Boot Mode
BOOT1 BOOT0
1 1 Reserved
1 0 Internal
0 1 Serial
0 0 Fuses

Connect the VisionCB-STD board to the host PC using microUSB cable connected to the USB-OTG connector. To observe progress/error reports during programming, please use serial console. If you are using standard VisionSOM carrier board (VisionCB-6ULL-STD), this can be done by using build in serial/usb converter.

Programming VisionSOM eMMC memory/uSD card

Flasher does not assume any specific partitions layout. It simply takes raw image of eMMC/SD card and writes it into the storage.

For image programming, use command:

uuu.exe -b vsom_6ull_emmc_flasher sdcard.img

(while: sdcard.img - raw image of SD card or eMMC memory)

At the command prompt, a progress bar will appear:

The serial terminal output will look like this:

If the process ends with success, a properly information will show on the command prompt:

The SoM will not boot due to present boot selector setup. Revert the boot selector back to: INTERNAL and press RESET. The board should start booting.
