WebJul 1, 2012 · You copy the data from block 1 with the ECC BUT when you write the data to a new Nand-flash device, you are cloning the data. If that new nand-flash device has an error in position 1. Then the data you write back will be wrong on the following read, because position 1 is bad. WebSPI NAND Flash supports Quad SPI operation when using the x4 and Quad IO commands. These commands allow data to be transferred to or from the device at four times the rate of the standard SPI. When using the Quad SPI command the SI and SO pins become bidirectional I/O pins: SIO0 and SIO1, and WP# and HOLD# pins become SIO2 and SIO3.
