mmc0: Timeout waiting for hardware cmd interrupt.

[TrinathK]

Hi,

Greetings of the day!

I am using custom LS1046 board with SD boot. I am getting below error messages and system got hanged after that. After power on and running my application for almost 2 hours, i am getting this error. sometimes i am getting this just for 15 minutes of running application. I am using LSDK 20.12.

Is this issue anywhere related to Table 8. LSDK 21.08 closed issues.

QLINUX-6595 : In LS1046A RDB, transfer complete interrupt
should be generated by eSDHC controller after
it sends CMD18 (multiple blocks read) to card.
However, after sleep, this interrupt did not
occur for CMD18 and this caused software
to report hardware timeout issue.
