3. When we read/write SPI, we use memory read/write instead of sending SPI command.
We have to be careful with SPI write. Some chips only support single-byte write, others allow 128-byte write and even others allow 256-byte write. I have a small patch which will allow using 8-byte writes on selected chips with SPI commands on SB600 and will send that patch soon. Regards, Carl-Daniel -- http://www.hailfinger.org/
