LTDC getting underrun interrupt when not enabled

[PCevo.1]

Trying to bring up a bootloader. On the last step and having difficulty getting the screen working. All the LTDC initialization looks ok and am enabled the line interrupt and the transfer error interrupt. When enabling the LTDC getting slammed with underrun interrupts. Even if tweaking the handle to automatically clean the underrun interrupt they just keep coming. Anybody run into this or any suggestions?

Hello @PCevo.1​ ,

Could you please provide more details on the issue:

• Which STM32 product you are using?
• Are you using an ST example?

If not, I advise you to start with an available example in the package.

Thank you.
