http://events17.linuxfoundation.org/sites/events/files/slides/An%20Introduction%20to%20SPI-NOR%20Subsystem%20-%20v3_0.pdf WebI'm using two different SPI Flash memories with a TM4C129X. Same problem with both chips. I want to read, erase and write the whole chips in bulk. I have some problems with the SPI it seems. I suspect it's a /CS signal problem. Flash command, Address and Datavector, needs to be read/written in one frame while /CS is contiguously low.
