Hi,
We have a problem when we debug SPI-CAN on Jetson nano.( 2-Channel CAN-BUS(FD) Shield for Raspberry Pi (MCP2518FD) /https://www.seeedstudio.com/CAN-BUS-FD-HAT-for-Raspberry-Pi-p-4742.html )
Can you help to check about this bug(hw or sw) on jetson nano? Thanks so much.
dmesg log: (boot up)
mcp25xxfd spi0.0 can0: MCP2518FD rev0.0 (-RX_INT -MAB_NO_WARN +CRC_REG +CRC_RX +CRC_TX +ECC -HD m:20.00MHz
r:18.50MHz e:0.00MHz) successfully initialized.
$sudo ip link set can0 up type can bitrate 1000000 dbitrate 8000000 restart-ms 1000 berr-reporting on fd on
We got a dmesg log and after a few minutes, Jetson nano rebooted as:
mcp25xxfd spi0.0 can0: Controller failed to enter mode Mixed (CAN FD/CAN 2.0) Mode (0) and stays in Configuration Mode (4).
