When I boot up the LX2160ardb_rev2 platform, sometimes it will appear mmc error message

Hi

When I boot up my LX2160ardb_rev2 board, sometimes it will appear MMC error message
The following is the error message

mmc1: Tuning failed, falling back to fixed sampling clock
mmc1: switch to high-speed from hs200 failed, err:-110
mmc1: Tuning timeout, falling back to fixed sampling clock

I want to know which cause it happens and fix it.

Thanks

Frank

Please try whether this problem could be fixed by the following patch.

https://patchwork.kernel.org/project/linux-mmc/patch/20201110071314.3868-1-yangbo.lu@nxp.com/

Apply erratum workaround of unreliable pulse width detection to
more affected platforms (LX2160A Rev2.0 and LS1028A Rev1.0).

If your problem remains, please provide your whole booting up log.

Would you please use LSDK 2004 images on your target board? I attached flexbuild_lsdk2004_update_290520.tgz to you.

Please download images with the following command.

$ flex-installer -i download -m lx2160ardb

Then deploy LSDK images to SD card on Linux host machine with the following command.

$ flex-installer -b <bootpartition> -r <rootfs> -f <firmware> -d <device>
