Hi,
I'm testing #3162 "Flash driver for QUADSPI interface in various STM32
variants." on stm32f7discovery board,
however I can't neither program or erase the QSPI flash.
Here the output of program:
openocd -f board/stm32f7discovery.cfg -c "program
Debug-MB1191B-0/Demo_Slider_Hor.elf verify reset exit"
