Hello,

I don't know which H5 part number you are using. Let's assume you are referring to the STM32H56x/57x.

If you look at the reference manual RM0481 rev 2/ Table 134. Programmed GPDMA1/2 request: there is no DMA requests from FDCAN peripheral(s). So the answer is no, you can't use GPDMA with FDCAN.
