flash_management's Issues

Cannot f_mount() even though f_mkfs()

Hello Mr. Andrew

Firstly, thank you very much for this source code which helps me a lot. In my case, I also use STM32 and Micron NAND flash, they work ok with I/O SPI interface between STM32 and NAND flash but when I cannot f_mount() even though I use f_mkfs() like your code. Can you help me with my situation and have you tried using f_write and f_read with this code? Thank you.

FRESULT res = f_mount(&fs, "", 1);
if (FR_OK == res) {
shell_prints_line("f_mount succeeded!");
}
else {
shell_printf_line("f_mount failed, result: %d.", res);
}
// if filesystem mount failed due to no filesystem, attempt to make it
if (FR_NO_FILESYSTEM == res) {
shell_prints_line("No filesystem present. Attempting to make file system..");
uint8_t *work_buffer = mem_alloc(FF_MAX_SS);

shell_prints_line("Unable to allocate f_mkfs work buffer. File system not created.");

res = f_mkfs("", 0, work_buffer, FF_MAX_SS);
