imx8mp emmc cache flush error -110

During the emmc rootfs mount phase, my cunstom imx8mp device occasionally has this error. Looks like it has something to do with emmc cache flush.

Does anyone know what could be causing this?  What are the risks?

Hi,

Can you share your eMMC type and part of the schematic where eMMC is connected to the CPU?

This will help to understand where the problem comes from.

Did you add CQE patch as described here:
https://community.nxp.com/t5/i-MX-Processors/eMMC-message-quot-mmc2-running-CQE-recovery-quot/m-p/10...

?

Hello, @artsiomstaliaro 

No. In that patch you mentioned, they remove CQHCI feature form imx8 ESDHC controller driver. As you know CQE is used to improve emmc performance, so i think it is not a best choice to apply that patch.

the current workaround is  that we  disable EMMC command queue feature, the root cause  is still
not identify, and under debugging

NXP guys mentioned that it works, you should try this patch and test the system.

Another alternative- is to reduce clock speed. Maybe issues with the layout.
