Can someone tell me how to use the command 1-2-2, 1-4-4 to read flash data of FU540 board ?
At present, I can read flash data through 1-1-1, 1-1-2, 1-1-4 commands,
But reading data with 1-2-2 and 1-4-4 is wrong.
Does there need any special settings for these two commands ?
I set up Frame Format Register(0x40) to change SPI protocol.
