imx51evk and u-boot

[Mauro Ziliani]

Hi all.

I'm trying to build Yocto dunfell for imx51evk derived board.

The board has only sd card with 1 dram of ram.


It is better u-boot-imx or u-boot-fslc as bootloader?


I try the two version of u-boot but I get only the presentation of uboot.

Uboot is not able to boot

u-boot-fslc

you tried them lately?

imx51evk has 512MB of RAM.

You need to adapt the DDR for your specific board to be able to boot it.

Yes, it boots well with the top of tree U-Boot:

Yes, this is expected.

You are using the U-Boot mx51evk target, but your board is a custom one.

You said it has 1GB of RAM, so you need to adapt the DDR
initialization to your custom board.

Using the imx51evk target with your board does not work.

Sorry for my offtopic.

I need to study better the schema


Thanks for your time.
