STM32H743 FDCAN Message RAM Configuration

[jerry2]

There are several FDCAN peripheral registers on the STM32H743 that hold the starting address of various elements used for FIFOs and filters. Are these addresses relative to 0 or to the physical address of the FDCAN message RAM (0x4000AC00)? The Reference Manual doesn't make this clear.

Hello @jerry2​ ,

Please refer to this AN5348 "FDCAN peripheral on STM32 devices", in the section "4.2 RAM management ", this will help you on RAM configuration.

Best Regards,
