Hai...,

I am using STM32F746IGT custom board (Waveshare) and 7 inch display (1024x600) with TouchGFX 4.17.0 and External Flash, SDRAM it all working fine. Display also shows fine.

I am using Touch driver (ft5336 or ft6x60 ) both are get from sample program.

If i int followed functions in STM32TouchController.cpp file

BSP_TS_Init(1024, 600);

or

BSP_TS_GetState(&state);

While Debugging time '' void MemManage_Handler(void) '' fault will occur display it shows RGB colors or flickering.

Just disabled this two functions display working normally.

What happen in BSP_TS functions. Where i need to manage the memory.

Please give me a idea for about this problem.

Best Regards.

M.Govind

Hello GMano.1,

You have access to the code of BSP_TS_Init(). You can see what it is doing for yourself.

Also your board is Waveshare and you have a custom display which could lead to some error I cannot guess.

If you post the code of BSP_TS_Init here, it will be easier to help you.

Moreover, if you could debug and tell us where exactly the fault occurs, this would also be helpful.
