Hello,
I am trying to reconfigure my STM32H735G-DK to use HSI instead of HSE for a TouchGFX based application.
The Default config (at a high level):
HSE Source, main CPU at 550 MHz and peripheral bus at 275 MHz or 137.5 MHz; OSPI at 200 MHz and LTDC at 9.6 MHz
The HSE custom clocked (this worked):
HSE Source, main CPU at 400 MHz and peripheral bus at 200 MHz or 100 MHz; OSPI at 192 MHz and LTDC at 10 MHz
Next I replicated the same clock output as the HSE custom setup, but using HSI as input.
This time the code build okay, but each time I flashed, all I got is a blank screen on the LCD.
Is there any limitation where the clock has to be HSE to use with LCD/TouchGFX or am I missing something?
Thank you for everyone's time
