I am trying to and read and write to a mico SD card via SPI using the UCANS32K146 development board and the Fatfs driver, but I get an error at CMD17 (read single block).
This is the process:
1. Send CMD0.... receives 0x01
2. Send CMD8.... receives 0x00
3. Send CMD17.... and receives 0xC0 (with a 2GB card) and 0xFF (with a 16GB card). This is where it fails as it is expecting a value of zero.
This is happening during when the 'f_open' function is called from main()...
LPSPI0_init_master();
f_mount(&FatFs, "", 1); /* Give a work area to the default drive */
fr = f_open(&Fil, "newfile.txt", FA_WRITE | FA_CREATE_ALWAYS); /* Create a file */
if (fr == FR_OK) {
f_write(&Fil, "It works!\r\n", 11, &bw); /* Write data to the file */
fr = f_close(&Fil); /* Close the file */
}
The SD card board is a Digilent 410-380 connected to SPI0 on the NXP board...
The code is attached for reference and code originally came from this post...
