Reply To: SD Card "RAW" Clone
Hi Thank you, yea I was still unclear in my post about the “Master” concept. I used that term NOT in the context of ths SPI bus but as my Master SD card, with the information on to be duplicated in it’s entirety.
I will use two SD card sockets and one SPI port. The pic I’m using have 3K Ram for buffer purpose.
So we are clear that I can do a sector read to buffer, sector write from buffer to unformatted SD card for cloning/duplicating.
To format a blanc SD card, just clone a formatted SD card to a unformatted SD card in that way, right ?
