Hello!
How can we set the hardware filters on a i.MX 6ULL which is running Alpine Linux? One of the devices in the CAN bus can sometimes generate sustained high loads of traffic, which although not meant for the iMX, the i.MX still processes them.
Now, the setup is the following: the i.MX actually runs Docker, where an application uses CAN via SocketCAN and does configure the CAN filters, but the bare-metal Linux still processes the IRQ of the CAN traffic. Is there a i.MX-specific can driver that allows us to configure the Hardware filters on the i.MX physical CAN transceiver? As per the datasheet, this is obviously possible, but using cangw or modprobe can does not support setting of filters.
Thank you!
