PIC18F & SD Card
I am trying to write SDHC EVO 32Gb with PIC18F without success.
Initialization, reading without problem.
My write sequence:
CMD16, 512byte, CRC 0x81
CMD24, Addresse, CRC 0x6f //WRITE_SINGLE_BLOCK
Send 512 byte data
Wait for 0x05 answer
0xE5 answer is coming (0xE5 & 0x1F = 0x05) but SD Card is blocked.
No more reading & initialization only after cut from supply.
Thanks for help.
