[IMX8MNDDR3L] Cannot flash with uuu using kirkstone BSP (Failed to configure default pinctrl)

[Krisna]

Hi there,

We have tried to generate IMX8MN image using zeus BSP, so far so good, but because it's already reach EOL, we plan to migrate to kirkstone BSP.

We use this xml to sync the sources:

$ repo init -u https://github.com/nxp-imx/imx-manifest -b imx-linux-kirkstone -m imx-5.15.71-2.0.0.xml

And we use these commands to build the image:

$ MACHINE=imx8mnddr3levk DISTRO=fsl-imx-wayland source ./imx-setup-release.sh -b build
$ bitbake core-image-minimal

We manage to build the image, but when we tried to flash it to 8MNANOD3L-EVK using uuu, it always stuck here:

uuu perspective:

C:\Work\Shared>uuu.exe -V -b emmc_all imx-boot-imx8mnddr3levk-sd.bin-flash_ddr3l_evk core-image-minimal-imx8mnddr3levk.wic

Failed to configure default pinctrl

Using zeus BSP, we never encounter such issue. And we find that sd.bin size is quite small on kirkstone (1.732 KB) compare to zeus (3.184 KB). Any hint would be appreciated. Thank you for your time and support.

Hi there,

After troubleshooting the whole day, found out that I need to change /build/tmp/work/imx8mnddr3levk-poky-linux/u-boot-imx/2022.04-r0/build/imx8mn_ddr3l_evk_config/.config

CONFIG_USB_GADGET_VENDOR_NUM=0x1fc9
CONFIG_USB_GADGET_PRODUCT_NUM=0x0152

to:

CONFIG_USB_GADGET_VENDOR_NUM=0x0525
CONFIG_USB_GADGET_PRODUCT_NUM=0xa4a5

And call:

bitbake u-boot-imx -c compile -f
bitbake core-image-minimal -f

Now I can use flash with uuu + u-boot without problem. I consider it to be a BSP bug though, hopefully it can be resolved on next released. Thanks.
