I guess issue is caused by incompatible setting in uboot,but have not found which exactly so i handled it like emmc. If patch is ready to be applied please add Cc: stable@xxxxxxxxxxxxxxx because all kernel versions are affected (tested at least in 5.4 and 5.9). If i need to create a v2,i will add it @sean/ryder/wenbin can you tell me if sd on mt7622/bpi-r64 is maybe capable of hs400? regards Frank
