Hello Everyone,
I tried the GFX02Z1 "HelloWorld" firmware example on the Nucleo H723ZG. Apparently the example does not work in DMA mode but alway gets stuck in DMA_TxErrorCallback. When switching to No DMA mode it works perfectly well.
Did anyone encounter the same problem? Due to performance issues I'd really like to have the DMA mode running.
I appreciate any help :)

Hello @meltabomeltabo,
Did you follow exactly the readme file, how the hardware connections?
It maybe the problem is related to memory layout and internal data cache (D-Cache) of the Cortex-M7 core.
