Flashing procedure
For flashing eMMC or SD card we need to perform several steps:
- change switch position S1 BOOT to: 1-off, 2-on (serial downloader mode)
- plug USB-C cable to PC and to board USB C connector
- prepare imx-boot and *.wic files
- run following commands for flashing media
eMMC
linux:
sudo ./uuu -b emmc_all <path to imx-boot file> <path to wic file>
windows:
C:\uuu>uuu.exe -b emmc_all <path to imx-boot file> <path to wic file>
SD
linux:
sudo ./uuu -b sd_all <path to imx-boot file> <path to wic file>
windows:
C:\uuu>uuu.exe -b sd_all <path to imx-boot file> <path to wic file>
After those steps eMMC or SD card is flashed and perform following steps to boot new image:
- unplug USB-C cable from PC
- change switch position S1 BOOT to: 1-on, 2-off (boot mode)
