with ENV_IS_NOWHERE disable board cannot boot

[marekb]

Hi, I'm integrating mender to imx93 evk and I'm hitting an issue that when I disable in u-boot CONFIG_ENV_IS_NOWHERE board hangs in SPL when flashing over uuu:

 Trying to boot from BOOTROM

Boot Stage: USB boot

Find img info 0x88000000, size 288

Any ideas why is this happening? I've tried to debug it but didn't find anything. When flash same image to SD card it boot without an issue. Thanks.

Any solution found for this issue? whenever I comment out this CONFIG_ENV_IS_NOWHERE=y, I can't flash our custom board. it just stuck like this "1:6-0F31300007298A0D>Start Cmd:SDPS: boot -scanterm -f tmp/deploy/images/imx8mp-lpddr4-evk/imx-boot-imx8mp-lpddr4-evk-sd.bin-flash_evk -scanlimited 0x800000
100%1:6-0F31300007298A0D>Okay (5.005s)"

This is the command that I use to flash:

wobaffet@wobaffet:~/imx-yocto-bsp/buildwayland$ sudo ../mfgtools/uuu/uuu -V -b emmc_all tmp/deploy/images/imx8mp-lpddr4-evk/imx-boot-imx8mp-lpddr4-evk-sd.bin-flash_evk tmp/deploy/images/imx8mp-lpddr4-evk/imx-image-core-imx8mp-lpddr4-evk-20241102114134.rootfs.wic.zst

Any comments?

Thanks!

Best Regards.

Hello,

Could you share what are you trying to flash?
Is it Android or Linux?

Also, could you share the tool (UUU) command you have used and the ouput from the tool?

Best regards/Saludos,
Aldo.

I'm flasing wic image basically which is generated by yocto. uuu command looks like ```uuu -b emmc_all <image_name.sdimg.zstd>

[AldoG]

Hello,

Thank you for sharing, please share the output of the tool, try running using verbose mode:

uuu -V -b emmc_all <image_name.sdimg.zstd>

And share the output.

Best regards/Saludos,
Aldo.

Hello,

Could you try decompressing the file and using the boot image and rootfs when attempting to flash?

SInce as per the log I cannot see clearly which boot image it is using, as I believe since no error is shown that only SPL is being loaded.

Best regards/Saludos,
Aldo.

[marekb]

Hi,

Can you be please more specific? IIRC sdimg contains boot image which is imx-boot and then rootfs. Is there a way how to flash them individually? Thanks.

[AldoG]

Hello,

indeed sdimg, should include the boot image packed, what i meant is that you're using the whole package (.zstd) for flashing, the tool is able to handle this, but for debug purpose please try to unpackage the sdimg and the boot image.

After this you may run the tool as usual:
uuu -V -b emmc_all <boot image> <rootfs>.sdimg

Also, please note that UUU needs to load uboot first, then it will flash rootfs and boot image.

Best regards/Saludos,
Aldo.
