It works, but an initial read on the mounted card results in the CRC errors until the system decides to switch to single reads (as listed at the end of the error message). I was just doing uprade to 4.6.3, but something must have went wrong after I ran jetson-io.py to configure my camera… I see other people complaining as well, but nobody found a satisfying solution. Setting sdhci.tegra.2 to “okay” and playing with mmc-ocr-power reduced the number of messages, but it is not the solution. I threw away the manufacturer documentation :).
