Thanks for the feedback. Please add these two patches to u-boot 2022.04.
https://github.com/TechNexion/u-boot-tn-imx/commit/e330b7a45dc7a2bfef9caeac0df4450f452a7ddd https://github.com/TechNexion/u-boot-tn-imx/commit/52d120f80742ca29eb890a05d7d6d3efe02ec112
Best Regards, Ray
I'm able to update using the instructions here: https://developer.technexion.com/docs/recover-to-factory-settings-pico-imx8m-mini However, I have trouble when attempting to update with the flash.bin created by with u-boot branch tn-imx_v2022.04_5.15.71_2.2.0-stable (tag tn-kirkstone_5.15.71-2.2.2_20240220).
After successfully building u-boot, I run './install_uboot_imx8.sh -t -b imx8mm-pico-pi.dtb -d /dev/null'. This also succeeds and produces imx-mkimage/iMX8M/flash.bin.
Unfortunately, attempting to update u-boot with 'sudo ../mfgtools/build/uuu/uuu -v -b emmc imx-mkimage/iMX8M/flash.bin' hangs after sending flash.bin:

Run built-in script:
uuu_version 1.2.39
@_flash.bin | bootloader
@_image [_flash.bin] | image burn to emmc, default is the same as bootloader
This command will be run when i.MX6/7 i.MX8MM, i.MX8MQ
SDP: boot -f imx-mkimage/iMX8M/flash.bin
This command will be run when ROM support stream mode
i.MX8QXP, i.MX8QM
SDPS: boot -f imx-mkimage/iMX8M/flash.bin
These commands will be run when use SPL and will be skipped if no spl
SDPU will be deprecated. please use SDPV instead of SDPU
{
SDPU: delay 1000 SDPU: write -f imx-mkimage/iMX8M/flash.bin -offset 0x57c00 SDPU: jump

These commands will be run when use SPL and will be skipped if no spl
if (SPL support SDPV)

Additionally, I see this from u-boot on the console:
U-Boot SPL 2022.04-00229-gd5886ef0c7 (Jun 12 2024 - 14:25:33 -0600) power_bd71837_init dram_init: LPDDR4 4GB DDRINFO: start DRAM init DDRINFO: DRAM rate 3000MTS DDRINFO:ddrphy calibration done DDRINFO: ddrmix config done SEC0: RNG instantiated Back to ROM, SDP
Seems some USB SPL settings are missing from pico-imx8mm_defconfig. NXP fixed over 2 years ago...
