Hello friends, I am developing a project and I'm using two CAN. The Can one is working, but the CAN 2 is not, i 'm recompile the kernel enabled the can 2, but I can not make it work. Scenario: - I can print the frames in CAN 2, I get in the kernel log (dmesg) and the frames are correct. - CAN 2 works normally if I disable the CAN 1 and recompile the kernel.
Problem: In the "rtcan_raw.c" in function "void rtcan_rcv (struct rtcan_device * dev, struct rtcan_skb * skb)" there is a verification "while (recv_listener! = NULL) " and the problem is that the variable "recv_listener" is equal to NULL . This variable comes from the function "static int rtcan_mscan_interrupt (rtdm_irq_t irq_handle *)" (which is on file rtcan_mscan.c) this function passes a struct as a parameter "dev = (struct rtcan_device *) rtdm_irq_get_arg (irq_handle, void)" to "rtcan_rcv" and it contains the recv_listener = dev-> recv_list. Soon the CAN2 is working but there are some configuration issues in this code. Can anyone help me with this problem? Thank you.
