i.MX8MQ EVK kernel 4.19.x SDHCI issue

[victoryu]

My hardware is i.MX8MQ EVK board. I use linux-imx branch imx_4.19.35_1.0.0. Build and compile are no problem. And I boot from SD card. But it will dead on sdhci, why ? The branch imx_4.14.98_2.0.0_ga is no problem. I need kernel version 4.19.x. Following my booting information piece :

I fix this problem. It is the i.MX8MQ SoC has error ERR011171 which will let the software irq fail. The software has working around solution in drivers/irqchip/irq-gic-v3.c. But this patch of branch 4.14.xx-ga is different other branch. I find that the branch 4.14.xx and 4.19.xx has the different solution. I guess the SoC version is different, so the software is different solution. Is it right ? But can I get the SoC version to use different solution ?

Hello,

Sorry for my delayed response, I did find the commit for this changes and seems to be  a re-work for this workaround doesn't seems to be a different SoC, until it is fully released (GA) this may change, so I'll recommend to look at this with your FAE, sorry for the inconvenience.

Thank you,

Best regards,

Aldo.

Aldo,

Yes. I find the answer again. It is not depended on different version SoC. It is depended on different version ATF.

Hello,

Unfortunately the version L4.19.x is not release yet, it is still on beta, sorry for the inconvenience.

Hope this helps,

Best regards,

Aldo

I try branch imx_4.14.98_2.2.0 to get the same error result. But the branch imx_4.14.98_2.0.0_ga is fine. What is the different between two branch ?

[AldoG]

Hello,

The L4.14.98_2.0.0_ga is full cycle tested and GA quality it is the recommended one for the same reason, for the difference between the 2 versions take a look to the git in the next link:

https://source.codeaurora.org/external/imx/linux-imx/diff/?h=imx_4.14.98_2.0.0_ga

Thank you,

Best regards,

Aldo.
