Hey there
I am using an custom board which has a stm32h743. I want to send data to an fpga with FMC bus. I know that FMC in stm32h7 is a 74-bit bus. In stm32cube I have configure 8-bit data and 8-bit address in SRAM mode. when I issue a 8-bit write it performs sequentially 8 time write. but I only want to do write only once. could you please tell me how I can do that?
I also have another question, When I enable Dcache and Icache, the FMC does not write to external device. is it possible to disable the cache of FMC?
thanks in advance.
