[U-Boot] imx8mq-evk boot regression

[Fabio Estevam]

Hi,

Just tried to boot imx8mq-evk using latest U-Boot master and this is what I get:

U-Boot SPL 2020.01-rc3-00070-g9a0cbae22a (Nov 25 2019 - 13:08:24 -0300)
PMIC:  PFUZE100 ID=0x10
DDRINFO: start DRAM init
DDRINFO:ddrphy calibration done
DDRINFO: ddrmix config done
Normal Boot
Trying to boot from MMC2

(It hangs here)

I haven't tried to debug this yet, but just wanted to let you know in
case this is a known issue.

Any ideas?

Thanks,

Fabio Estevam

Hi,

maybe I can find some time tomorrow to have a look at it.  One thing
you can try is https://patchwork.ozlabs.org/patch/1197351/ .  On my
employer's product this fixes a regression introduced by commit id
9e094455495081979cd20ac730a42508717e37b5.  But I think that should have
hit you somewhere before the print that you are seeing, so I guess that
is not it.

Thanks,
Patrick

Thanks for the suggestion. I tested the patch, but it did not help.

Maybe Peng has any suggestions?

Thanks

Hi,

just tried it here as well, and for me it gets to the U-Boot command-
line, but then there it cannot access the SD card anymore.  At least
that's further than what you have.
