Fatfs Example On Sdk 14 2 Initialization Error Disk State 1 Result: initialization error (disk state = 1). the analyzer shows that the spi master tries to communicate with the sd card, which does not answer at all (see attached picture).

Fatfs Example On Sdk 14 2 Initialization Error Disk State 1 On the 16 gb card i got 2 different errors (randomly): 1 (low level i o) and 13 (no valid fat volume). so i made a slow formatting (fat32, since fat is not available for size > 4gb) and re soldered the header pins of the card breakout.

This implementation of file system is developed by elm chan fatfs diskio.c at master · zephyrproject rtos fatfs. I want to connect a sd card (32gb, sandisk, fat32) with the f746g discovery board to save some data on it. (at first .txt files, later read .csv files to visualize some measuring data). my problem is, that the f mount function gives me a "fr ok" but in the next step i can't open a file with f open. i located the problem by debugging step by step. I still do not understand why you use the erase function at the begining, after formating the sd card, why dont you just use the f mount without the "erase" and then use the disk read. The disk initialize function initializes a physical drive and put it ready to read write. when the function succeeded, sta noinit flag in the return value is cleard.
