imx8mp emmc cache flush error -110

changbaoma — Mon, 04 Jul 2022 09:55:57 GMT

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.

Re: imx8mp emmc cache flush error -110

changbaoma — Mon, 04 Jul 2022 10:13:17 GMT

Hello, @artsiomstaliaro

eMMC type: FORESEE FEMDRW016G-88A43

Here is part of emmc schematic :

Please let me know if you need more information.

Re: imx8mp emmc cache flush error -110

artsiomstaliaro — Mon, 04 Jul 2022 17:47:28 GMT

Can you show also DTB settings related to eMMC?

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/1092607

Re: imx8mp emmc cache flush error -110

changbaoma — Wed, 06 Jul 2022 03:55:09 GMT

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.

Re: imx8mp emmc cache flush error -110

artsiomstaliaro — Thu, 07 Jul 2022 08:33:47 GMT

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.

Re: imx8mp emmc cache flush error -110

joanxie — Thu, 14 Jul 2022 09:21:09 GMT

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

Re: imx8mp emmc cache flush error -110

artsiomstaliaro — Thu, 14 Jul 2022 09:50:45 GMT

Is the problem there?

Re: imx8mp emmc cache flush error -110

artsiomstaliaro — Thu, 14 Jul 2022 09:51:46 GMT

Is this problem still there after disabling the feature?
