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.
