imx8mm-evk question: cannot flash bootloader via uuu tool

[bitterblossom5486]

Hi NXP community:

In recent days I am trying to burn the Yocto image in my imx8-mini board and I got an error when I was flashing the bootloader into the board as I said.

I referenced this document to generate my imx-robot-core-rt image strictly: https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX-%E6%9C%BA%E5%99%A8%E4%BA%BA%E5%B9%B...

And here is the error log:

Any idea about it? Thanks a lot!

Are you using NXP i.MX8MM EVK board? Which version BSP are you using, are you using the demo images or the images you build yourself?

[bitterblossom5486]

Well, neither demo image nor self-made image is not applicable. The processor is imx8mm but the baseboard is not.

[Rita_Wang]

Are the board you designed yourself? If yes, you need to do porting BSP first.

[bitterblossom5486]

I connected one more USB-RS232 cable to the baseboard, then I got more info from the serial port. Hopefully that will be helpful:

i.MX8MM has two type of evk board. 

1. i.MX8MM + LPDDR4 + emmc 

2. i.MX8MM + DDR4  + nand 

Which one you are using? 

If you are using i.MX8MM + DDR4  + nand  evk, it has no emmc. 

That is why the error output "invalid mmc device 2" and you cannot flash to emmc.

 I read the tutorial of uuu again: https://github.com/NXPmicro/mfgtools . Should I download a bootloader or flash it? I'm kind of confused 'cuz I cannot figure out these two concepts now sry for that. Did I use the incorrect bootloader flashing command? Anyway, the tutorial said that the bootloader should enable fastboot, then should I enable that mode manually?

[bitterblossom5486]

And the uuu tool I used is the latest version.
