@tinnedkarma , after testing, I encounter this weird issue with corrupted frame received from upperhalf. I would say about 10% defection. The CAN ID is always either corrupted to 0x0 or 0xC2008020. I initially tried with netpkt_copyout and current use netpkt_getdata but both have the same issue. ``` saluki> ifup can0 ifup can0...OK saluki> cansend can0 123#deadbeef [CPU2] mpfs_transmit: TX Frame: ID=0x123, DLC=4 [CPU2] mpfs_transmit: TX Debug: cf.can_id=0x123, msg_id=0x48C0000, shifted=0x24600000, DLC=4 [CPU2] mpfs_transmit: TX HW Write: addr=0x2010C020, ID_reg=0x24600000, data_high=0xDEADBEEF, data_low=0x0 [CPU0] mpfs_transmit: Sending CAN message (ID: 0x123, DLC: 4) via buffer 0 saluki> saluki> saluki> saluki> saluki> saluki> cansend can0 123#deadbeef [CPU0] mpfs_transmit: TX Frame: ID=0x0, DLC=0 [CPU0] mpfs_transmit: TX Debug: cf.can_id=0x0, msg_id=0x0, shifted=0x0, DLC=0 [CPU0] mpfs_transmit: TX HW Write: addr=0x2010C020, ID_reg=0x0, data_high=0x0, data_low=0x0 [CPU1] mpfs_transmit: Sending CAN message (ID: 0x0, DLC: 0) via buffer 0 saluki> saluki> saluki> cansend can0 123#deadbeef [CPU1] mpfs_transmit: TX Frame: ID=0x123, DLC=4 [CPU1] mpfs_transmit: TX Debug: cf.can_id=0x123, msg_id=0x48C0000, shifted=0x24600000, DLC=4 [CPU2] mpfs_transmit: TX HW Write: addr=0x2010C020, ID_reg=0x24600000, data_high=0xDEADBEEF, data_low=0x0 [CPU0] mpfs_transmit: Sending CAN message (ID: 0x123, DLC: 4) via buffer 0 saluki> saluki> saluki> cansend can0 123#deadbeef [CPU0] mpfs_transmit: TX Frame: ID=0x123, DLC=4 [CPU0] mpfs_transmit: TX Debug: cf.can_id=0x123, msg_id=0x48C0000, shifted=0x24600000, DLC=4 [CPU1] mpfs_transmit: TX HW Write: addr=0x2010C020, ID_reg=0x24600000, data_high=0xDEADBEEF, data_low=0x0 [CPU0] mpfs_transmit: Sending CAN message (ID: 0x123, DLC: 4) via buffer 0 saluki> saluki> cansend can0 123#deadbeef [CPU0] mpfs_transmit: TX Frame: ID=0x123, DLC=4 [CPU2] mpfs_transmit: TX Debug: cf.can_id=0x123, msg_id=0x48C0000, shifted=0x24600000, DLC=4 [CPU3] mpfs_transmit: TX HW Write: addr=0x2010C020, ID_reg=0x24600000, data_high=0xDEADBEEF, data_low=0x0 [CPU3] mpfs_transmit: Sending CAN message (ID: 0x123, DLC: 4) via buffer 0 ``` <img width="710" height="672" alt="image" src="https://github.com/user-attachments/assets/b13ce31c-84b0-4278-9618-d9367d03ae30"; /> -- This is an automated message from the Apache Git Service.
