Black screen on display after writing user program to flash for STM32F469I DISCO board
After compiling and programming in the flash memory using the STM32Cube IDE application of my application, most of the time after writing completely without having the well-known issue (error at the start or/and end of the flash memory that I don't understand why it is not solved) instead of displaying on the screen what I defined in the TouchGFX app, a black error is displayed. I have tried countless times to rewrite after doing a full erase but in vain.
I used the debugger and the program execution stops after 'osKernelStart()' in main.c with this error:
well-known issue
well-known issue
I have to rebuild the application again by deleting and drawing in TouchGFX and then opening in STM32CUBEMX and then in STM32CubeIDE, blah blah> . If I'm lucky enough not to get the flash programming error, very often encountered and discussed on this forum and for which I notice that no solution has been found, everything works fine. But sometime I need to modify the program and after reprogramming in flash I get the error, all my work is gone and I have to create a new application. Can you help me with this issue, is there something wrong with the STM32F469I DISCO board?
Has anyone else had this problem?
