Hi Fabio!

happy new year! Hope you are fine?

I just builded the newest mainline U-Boot code for the wandboard, and
I get:

U-Boot SPL 2020.01-tbot-00271-gd8a3f52 (Jan 08 2020 - 06:33:42 +0100)

Ethernet does not work, also pmic setup seems buggy... Hmm pmic is not
detected, and later board revision is B1 instead D1... I think thats
the root cause of the problem...

Attached a bootlog from an older, working version [1].

Ok, I tried to bisect it, but bisecting does not work, as there are
commits, which does not build for wandboard :-(

Looking into git history, there is a commit from you:

     wandboard: Add FIT image support

     After the transition to DM, only the mx6dl/solo wandboard
     is supported.

     Add FIT image support so that all the wandboard variants
     can be supported, like it was prior to the DM conversion.

     Successfully booted Linux on mx6q/solo/qp wandboards.

So it worked for you? I flashed the u-boot-fit-dtb.bin instead of
u-boot-dtb.bin, but this leads to:

resetting ...

U-Boot SPL 2020.01-tbot-00271-gd8a3f52 (Jan 08 2020 - 06:25:09 +0100)
Trying to boot from MMC1
mmc_load_image_raw_sector: mmc block read error
spl: ext4fs_open failed
spl_load_image_ext: error reading image u-boot-dtb.img, err - -1
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

Same with u-boot-with-spl.imx flashed.

I am sure I make here something wrong... any ideas?

Attached also a working bootlog with an older version [1].

Thanks!

bye,
Heiko
