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.
