Hello NXP team,
I am trying to flash my custom iMX6ULL devicehaving NAND flash. It is based on iMX6ULL EVK design
I have downloaded the YOCTO source and built it with UBOOT_CONFIG = "nand" in local.conf.
The image generated is u-boot-nand-2023.04-r0.imx
When I try flashing the device with the above mentioned u-boot, I am facing below error:
sudo uuu -v -V -pp 1 -b nand u-boot-nand-2023.04-r0.imx
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.5.21-0-g1f42172
Build in config:
Pctl Chip Vid Pid BcdVersion

I tried the prebuilt images from NXP , but it is also giving the same error. I tried the example uuu script as well, with the modifications needed. But I am facing the same issue.
If needed I can share the schematic of our custom board privately to get it reviewed.
Can you please help us resolving the issue?
Thanks!

Hello @JosephAtNXP ;
I tried what you suggested, but still I am facing the similar issue.
Can you suggest whether the issue is with the u-boot which I am building or something related to usb driver on host?
Attaching the generated u-boot for your reference.
Thanks!

Hi,
Thank you for your interest in NXP Semiconductor products,
You could try this porting guide but for 6ULL, i.e., you have to make modifications to support 6ULL's nand boot and there are in latest release as:
configs/mx6ull_14x14_evk_nand_defconfig
In that case, you'd take upon the test and update to latest release and latest UUU release, please update how did it went.
Regards
