Hi,
I'm using Nuleo-H743Zi2 hardware. I have configured FDCAN1 with below configurations,
hfdcan1.Instance = FDCAN1;
hfdcan1.Init.FrameFormat = FDCAN_FRAME_FD_BRS;
hfdcan1.Init.Mode = FDCAN_MODE_NORMA...
Our issue is not with respect to CAN is not working. It works. But sometime the receive interrupts are delayed/not triggering even after packet is received in hardware queue.
Yes, CAN transmission and reception are working but these changes affected other functionalities(previously working at 48Mhz like packet fragmentation). The HSE is 8MHz .
Hi @SofLit,CAN is working at 100, 75MHz, but some of the other functionalities (working previously) got affected by these changes. Is there any known issues with the HAL/FDCAN peripheral for this H7 series?
Hi @Ozone ,We used CAN trace, the CAN messages are received at the Hardware queue, but the interrupt is not triggered or triggered late(>500ms). If the interrupt not triggered means, later when interrupt triggers, the previous message gets handled.
