Question

STM32CubeMX STM32H750 Ethernet DMA Address warning incorrect.

Minor bug, but it threw me off for a bit. When selecting ETH for the STM32H750, in the Parameter Settings there is a warning that ETH can only work with address 0x2400_0000. That is actually D1 SRAM which is not accessible by the Ethernet MAC, it needs to be D2 SRAM. The actual settings below (0x3004_0000) are correct, but the warning is incorrect.

I don't have Ethernet working yet, but hopefully soon...

...and forgot to also mention that those RAM settings get ignored anyway with Atollic/CubeIDE. For Kiel/IAR the generated code puts those buffers in the designated areas, but for Atollic/CubeIDE it just creates the data structures without any location overrides, so they get thrown in the default area which is DTCM.
