@alexc @qq20739111 I would be very surprised if the UART log showed anything other than mine. You can find it attached above.

@humanus Thanks, just noticed the log.

Interestingly looks like it's the mmc part. A few things I can think of:

1. emmc is only presented on A7A/S, so if you are using emmc or your board has an emmc, it might be a problem. You can try to disable sdc2 on device tree and see if it works.

1. sd card part is the same on A7A/S/Z, but I don't think my card is a UHS-II card. Looking at the log, it might be doing something with UHS-II, so it might be worth trying a different SD card to see if it behaves differently. If it does turn out to be related to UHS-II handling, I can look into a proper fix later. on.

I have no eMMC and the card isn't UHS-II (I use WD Purple cards, they are UHS-I). I don't think I have any UHS-II cards at the moment... Could try a different one though.
