Resolved! Writing and reading to external NORFlash using QuadSPI on STM32H743 mcu and successfully test erase, write, and read the flash a few days ago but now only read works. What could cause the erase and write command to not fail but not work either?

A few days ago I successfully tested erasing the NORFlash as entire chip erase, block erase, and sector erase. I also was able to write a string to Flash and read the string back out of Flash into a buffer. After working on other development I came ...
