I am trying to run the periph_sdmmc example from LPCOpen.
Used Hardware is OM13073 Evalboard (LPC43S37) and OM13082 rev. B (General Purpose Shield)
I added the code to initialize the GPIO1_12 to power the SD card (as required on the rev. B Shield).
When calling this function
rc = f_open(&Fil, "HELLO.TXT", FA_WRITE | FA_CREATE_ALWAYS);
I get "Failed with rc=1." on the debug log..
Initilizing the disk works fine with
stat = disk_initialize(fs->drv); /* Initialize the physical drive */
but when it comes to
fmt = check_fs(fs, bsect = 0);
fmt is 3: Disk error
digging a bit more into the library (in the function check_fs(..) )
status = sdmmc_execute_command(pSDMMC, CMD_READ_SINGLE, index, 0 | MCI_INT_DATA_OVER); (line 527 in sdmmc_18xx_43xx.c)
status is 32812 ( MCI_INT_EBE | MCI_INT_DATA_OVER | MCI_INT_CMD_DONE) when trying to read the first sector for information about FAT...
Unfortunately I did not find any information about End-bit error...
If someone knows how to fix this problem, please let me know
