Hi, all
I am trying to port android kernel on cyclone v.
When I try to change the kernel and root file system generated from android brillo branch which linux kernel is Linux-3.18.0-gbd355208-dirty, there will have SD card access errors(mmcblk0: error -84 transferring data, sector 14336, nr 8, cmd response 0x900, card status 0x0)
However, when I try to boot linux kernel from SD card, everything is ok. It means my SD card is OK, hardware platform is OK as well.
Can anyone give me some advice how to solve this issue? Thanks a lot.
Following is my console log:
