How to realize touchgfx display in stm32l4r9 using OSPI memory mapping mode?
- The flash loader has been successfully made.
- The OSPI memory mapping mode has been verified successfully.
Question:
When touchgfx designer selects extflash, the screen is black, and it is normal to switch to intflash。。。。
I feel incredible，can't find out the cause of the problem:tired_face:
Do I need to modify any files of touchgfx?
