I am currently working for the interface controller and it interface the two different CAN speed.But sometimes the received CAN buffer looks is overwriting with new messages under high CAN messaged load conditions.These are FDCAN1 and FDCAN2 setting ...
Hello EveryoneI am struggling to get STM32G474 FDCAN working, especially error handling. Normal transmission works fine. I use TXQueue (not TXFifo) mode. I can write messages to each of the 3 message buffers. Messages are sent, I get a Transmit Occur...
The configuration:STLINK-V3SETConnected the two PCBs together via the three connectors (page 11).Attached jumper JP7 CAN_ON on MB1440 PCB (page 18).(STLINK-V3SET pages 17 & 23) & (NUCLEO-H723ZG page 37) & (Bootloader AN page 199) & (STM32H723 Manual ...
I have been simulating errors on the bus by removing the other node (a motor controller). As expected I see a number of failed transmissions. I can see that the FDCAN peripheral signals an Active Error on the bus (presumably as a result of not gettin...
Hi,I've tried finding a document that would describe what do the different error codes mean for the CAN FD module.Does anyone have a link or an idea where to search from?My CAN FD peripheral ends up in error status 516 at some point and I can't find ...
I was trying to use FDCAN when I came across a problem where FDCAN_CCCR.Init bit is not getting cleared. The CCE bit gets cleared when setting INIT to 0, but INIT stays unchanged. Any ideas what could be wrong? I came across this topic where they had...
I am using CAN bus on my project and I am using NUCLEO-H753ZI board. The second board is nvdia orin nx. I also using CAN to USB converter to monitor the frames. When STM32 send the frame it is received on CAN to USB converter software without error ...
Hello, I am trying to make FDCAN work but I am not receiving any messages. The TX is working fine but when trying to receive messages the interrupt is not triggered. I am using STM32H7 series with freertos. I have set the filter, started FDCAN, enab...
Hello, I am trying to use FDCAN but for some reason interrupt is not triggering. Im using PEAK CAN to send and recieve messages. With osciloscope I can see the data being transfared to the STM board but the interrupt doesn't trigger. The speed I wa...
Hi AllI'm having a problem with FDCAN transmissions and would appreciate any insights. I have a pair of H563ZI Nucleo boards, and am transmitting FDCAN messages, but the 20th of the 29 bits in the FDCAN extended identifier is always received as 1, r...
