The NFC I am using doesn't give read/write access to spare area. 2. I have to write 512 bytes at a time or read 512 bytes at a time. 3. I don't have access to status, ready/busy pin. Please tell me what auto placement strategy I need to adopt. What ECC scheme I need to use. It has a HW ECC Generator but I don't have access to the value of ECC. I only get an interrupt if there is a ECC mismatch. Best regards Ranga Raju B
