Hi,
The genmask of regsiter SSCR, BPCR & others were setted accordly to
the chipset stm32f4.
So that means:
F4 -> 2048x2048 framebuffer
H7/MP1 -> 4096x4096 framebuffer
?
Worse
F4 is 2048x2048
F7 is 4096x2048

MP1 is 4096x4096
and there is no IDR

Hi Marek,
The genmask of regsiter SSCR, BPCR & others were setted accordly to the
chipset stm32f4.
You can see more details on page 493 of reference manual RM0090:

With future hardware, all of these registers will aligned on
Hi Marek,
thanks for the patch.
