Writing system image to eMMC memory


Prerequisites

  • PC with Linux Ubuntu 18.04
  • A complete package with NXP UUU application - uuu.zip
  • Built and extracted system image file called image.wic (from Yocto build tmp/deploy/images/visioncb-6ull-std/imx-image-multimedia-visioncb-6ull-std.wic.bz2)
  • Built bootloader binary u-boot.imx (from Yocto build tmp/deploy/images/visioncb-6ull-std/u-boot.imx)

Information

The uuu.zip archive contains the compiled NXP uuu binary for Linux, the commands script and the bootloader supporting fastboot command. The script required the image.wic and u-boot.imx files to be in the same directory.

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-6ULL-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.

Linux host PC

For image programing, use command:

sudo ./uuu -v vsom-6ull-cmds

At the console, a progress bar will appear:

If the process ends with success, the following information will be shown on the console:

The serial terminal output will look like this:

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.
