STM32CubeIDE official example: FATFS + 16/32GB SD card returns FR_NOT_READY
Hi,
I pull out the official example from IDE, and do a debug run.
I found out that the initialization always return FR_NOT_READY , after running to this line
res = f_mkfs((TCHAR const*)SDPath, FM_ANY, 0, workBuffer, sizeof(workBuffer));
- inside this line, it goes to ff.c and reaches the following lines:
/* Check physical drive status */
stat = disk_initialize(pdrv);
if (stat & STA_NOINIT) return FR_NOT_READY;
and STAT is always = 1 (failed)
This example was taken from IDE's EXAMPLE SELECTOR, should be official, and bug-free.
Anyone has any clue what to do when FR_NOT_READY is faced?
It is not cards problem, my 2 cards works normal on PC, and formatted with 4096 size, the max of STM's FATFS can handle.
