A real simple questoin here,
I'm a hardware guy...
Looking at the stm32F7 data sheets, and using the fmc in NOR flash mode.
From the software perspective, would you have a lump of code that does the sequence of instructions to do the write to the NOR ?
I have a off the wall idea to use the NOR interface to access to an FPGA If I can have the NOR flash bus timings, without the overhead of the write instructions and poling , then that would be faster / lower latency than a SRAM interface due to the lack of synchronization needed.
