Onboard SD card doesn't work anymore after the 'mmc-v5.4-2' updates

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

We have patched the RC2 [1] and RC3 [2] of kernel 5.4 with the mmc3 patch [3] and after that the onboard SD card works without any problems with them.

Could you please add this patch or do you have another solution?

Thanks,
Christian

-------------------------

I have found the issue in the DMA changes of the 'mmc-v5.4-2' updates. It's the commit "121bd08b029e03404c451bb237729cdff76eafed (mmc: sdhci-of-esdhc: set DMA snooping based on DMA coherence)" [3].

Please find attached a patch. This patch solves the issue.

dmesg output after compiling with the attached patch:

[   12.117149] mmc0: SDHCI controller on ffe114000.sdhc [ffe114000.sdhc] using ADMA

Please check the commit "121bd08b029e03404c451bb237729cdff76eafed" [3].

Thanks,
