Recans A0 has two controllers, one is based on RP2040, the other on MCP2515.
To bring up the RP2040 CAN controller:
sudo ip link set can0 type can bitrate 1000000 sudo ip link set up can0 sudo ifconfig can0 txqueuelen 128
The MCP2515 CAN controller
sudo mount -o remount,rw /boot sudo armbian-add-overlay /boot/overlay-user/sun50i-a64-mcp251x.dts sudo mount -o remount,ro /boot
sudo ip link set can1 type can bitrate 1000000 sudo ip link set up can1 sudo ifconfig can1 txqueuelen 128
Interrupt: STEP7 = PL11
Errata
- SPI_CLK and SPI_MOSI are interchanged and need to be fixed.
- /RESET is floating.
