AHB write over flexSPI

Question asked by Jeff Hane on Aug 15, 2019

I'm looking at the linux driver for flexspi, fsl-flexspi.c and I'm working with an iMX8.   The reference manual states the following:  Memory mapped read/write access by AHB Bus.   However, the driver does memory mapped reads, it's still using the IP commands and TFDR register for writes.   


 Anyone know what this is the case?
