hii tried with macronix_ram mode there the entire data is corrupting. but when i configure on regular macronix mode and tried to write and read from the particular addresses its working fine ( addresses - 0x90000000,0x90000020,0x90000040...etc. manu...

i think am facing issue while using memory mapped mode. I assume it will be issue with the address bit assignment, in most of the example application from ST I can see some linear address mapping likeAPS1604M- IS66WVS4M8ALL/BLL But in my case the f...
