MIPI DSI Clock not starting

[DAllo]

I've configured a skeleton CubeMX project upon which ive enabled the DMA2D, DSIHOST and LTDC IPs for a custom board. The boards test okay, access to the MCU, programming, sane registers, but upon flashing the CubeMX generated firmware the DSI clock signal doesn't present itself on the oscilloscope.

Am I missing something simple?

Still battling this, and yet to see a clock output from the CubeMX generated configuration. It's somewhat frustrating, i've tried emulating as best I can what I see in the DSI examples, but nothing seems to work. Is there some undocumented magic?

Were you ever able to get anywhere with this? I know it's a few years old at this point but I'm having the same problem right now on a STM32U5 board.

If anyone has come across this problem before and solved it, could they post the solution here? We are facing this problem now using the STM32F769.
