MCP2515 crash after one message everytime
I recently made a pcb with multiple IC, an raspberry pi, an mcu and two MCP2515.
To bring up the MCP2515, I added these line /boot/config.txt
dtoverlay=mcp2515-can1,spi0-0,oscillator=8000000,interrupt=25 dtoverlay=mcp2515-can0,spi0-1,oscillator=8000000,interrupt=24 dtoverlay=spi-bcm2835-overlay after a reboot, i set up the bitrate to 500kbits with the command
sudo ip link set can1 up type can bitrate 500000 and when I try to send a message with cansend, The MCU catch it and the message receive is right, but after that the MCP2515 doesn't do anything (can't send, or receive anymore) until i reboot the board. Once i rebooted the board I can once again only send one message.
I was curious if anybody got the same problem before
