Hi,
I am trying to port mmc driver to my board with little assistance from atmel_mci driver. While i was trying to understand the mmc_cmd function, i think i found a bug in it.
File -> uboot-1.3.1\cpu\at32ap\atmel_mci.c
Function -> static int mmc_cmd(unsigned long cmd, unsigned long arg, void *resp, unsigned long flags)
In Function, mmc_cmd , variable "error_flags" is 1st assigned to ERROR_FLAGS and then modified according to response type.
error_flags = ERROR_FLAGS; if (!(flags & RESP_NO_CRC)) error_flags |= MMCI_BIT(RCRCE);
However once the command is sent and a response is received, the driver checks for status
if (status & ERROR_FLAGS) { printf("mmc: command %lu failed (status: 0x%08lx)\n", cmd, status); return -EIO; }
But here, it checks for ERROR_FLAGS, while i think it was suppose to check for error_flags.
Kindly correct me if i am wrong.
Thanks in advance
