Dear @Tesla DeLorean
I am using NUCLEO-G491RE board and i want to create external flash loader for W25Q64JVSSIQ QSPI flash memory. I used external loader files from Github and build the .stldr file and placed in CubeProgrammer. when i try to read from 0x90000000 location, i am getting read failure error. I used the below path to create external loader for W25Q64JVSSIQ QSPI flash memory,
Driver code is working fine since I am able to see the data in memory mapped mode with test code provided in the github link.
But, when create a external loader using github files and placed .stldr file into cubeprogrammer and working on read/write/erase and these operations are failing.
Could you please check my project and do needful. PFA for my loader project
Thanks
