How do I trace all LTDC signals in STM32F746NG discovery board

[n.serina]

Hi,

ST's discovery boards usually have debug pin headers, but interestingly ST has removed it in the STM32F746NG-DISC board. I want to debug all LTDC signals by connecting to the oscilloscope. How do I go about that? Please help. Thank you.

The CAD files are available for that board. You can trace them from the MCU or from the display and find appropriate spots to tap into the signal. Won't be easy, but is doable if you have the tools (especially) and skill.

Should be able to get the display up an running using existing examples rather than doing low level debug. Might be easier and simpler.
