Since the BDMA controller on STM32H7xx can only reach SRAM4 it would be great to have an easy way to disable caching for this region using a simple define at mcuconf.h. Very much like they are available for SRAM1, SRAM2 and SRAM3. Especially since talking to SRAM4 is very inefficient for most other subsystems i think most people will only use SRAM4 in connection with BDMA.
The attached patch uses the MPU region 5 to disable caching for SRAM4. It would be great if you would consider adding this patch or something similar to the STM32 HAL.
Use this forum for requesting small changes in ChibiOS. Large changes should be discussed in the development forum. This forum is NOT for support.
