Hello,
I'm trying to use the GPU2D on the STM32N6570-DK, with NemaGFX.
However, the GPU hangs on random functions.
Well actually every time the same funtions, but depending on the number of functions to be executed, so it seems it can only execute a limited number of functions, and the it hangs.
And many of these doen't even complete the drawing of the shape.
The nema_vg_draw_circle doesn't complete drawing the circle and hangs.
When only drawing the rounded rectangle results in an incomplte draw and hang of the function:
If I remove some functions, the app hangs on nema_cl_wait.
I think it might be related to the buffer initialization in nema_hal.c, or that nema_hal.c contains other errors.

I noticed that the m55 NemaGFX works well with NEMA_RGB565, but not at all with NEMA_BGR565, which also took me a while to figure out. So there could be more surprises why it's not working right now.
I probably forgot something important.
Any help is appreciated.
BTW, on a STM32U5G9J-DK2 (m33) all works fine!
I posted my test project on hithub:
https://github.com/AngryCarrot61/STM32N6-digits-lcd
I noticed the versions below:
STM32U5x9 v3.5.0 - Works fine, no problems at all
STM32H7RS v1.3.0 - Reveals rendering issues with the vg libraries
STM32N6 v1.3.0 - Reveals rendering issues with the vg libraries
So I assume the NemaGFX v1.3.0 versions for the m7 and m55 aren't finished yet, regarding the vg libraries.
I also noticed the STM32N6 has a bug when using the NEMA_BGR565 format, while NEMA_RGB565 works fine.
