[CAN BUS support orange pi zero]

There was a new problem.
The system worked with a flash drive.
I transferred to internal memory. And orange stopped booting!
If I disconnect the interrupt pin, orange is loaded ...
In what there can be a problem, how it to win?

I'm glad to see that it every thing worked out !

I have some of those MCP2515 modules on my desk since more than a month, but  never got chance/time try them out ...

 

If you find the time, try different pins for interrupts, for me it is not entirely clear why it was PA2, but when connected to other pins, orange could not reboot

[CAN BUS support orange pi zero]

Everything worked!

I tried various pins to interrupt and with PA2 worked without errors. Thank you all for the help!

[CAN BUS support orange pi zero]

After all the fixes, errors ceased to appear and the interface can0 appeared! Thank you!

I connected the interrupt pin to PA7, orange is loaded normally, but when I execute the reboot command, orange does not load. When the interrupt terminal is connected, the orange can not normally reboot.

What can be done about this?

 

If I disable the interrupt pin, the orange is loaded and the can-modules also.
Next, I connect can0:
Ip link set can0 up type can bitrate 250000

 

I try to forward the message:
Cansend can0 100 # 43414e2054650000

 

I see this message on another device connected to another computer.

 

But the re-sending does not work and command "candump can0" does not show anything either. Perhaps this is due to the disconnected interrupt pin. But when the output is connected it is not possible to restart the orange. In what here there can be a problem?

Leave the PA13 as SPI_CS, and choose any other free GPIO for the IRQ, could be the original PA7.

My connection with the module:

4 VCC

6 GND

19 - GPIO 15 - MOSI
21 - GPIO 16 - MISO
23 - GPIO 14 - CLK
24 - GPIO 13 - CS0

It's right?

Is it necessary to connect a pin-INT on the module mcp2515, or without it to worked?

PA13 : single pin cannot be IRQ and SPI_CS at the same time ...

What pin should I choose?

On Zero SPI bus 0 is wired to the SPI flash pads (even if the flash itself it's not soldered), and SPI bus 1 is wired to the pin headers, so it should be

target = <&spi1>;

instead

Corrected

Need help!

I'm trying to connect the mcp2515 module to the Orange Pi Zero 2+ H3, but I can not. Dmesg wrote:
[8.572220] mcp251x spi0.0: Can not initialize MCP2515. Wrong wiring?
[8.572248] mcp251x spi0.0: Probe failed, err = 19

 

The OS is assembled from a night assembly with CAN-BUS support:
Root @ orangepizeroplus2: ~ # uname -a
Linux orangepizeroplus2 4.11.9-sun8i # 17 SMP Sat Jul 29 00:21:32 CEST 2017 armv7l armv7l armv7l GNU / Linux

I connect modules without problems:
Modprobe can
Modprobe can-dev
Modprobe mcp251x

I use this overlay (PA7 is replaced with PA13 according to the pinout: this and this):
https://github.com/armbian/sunxi-DT-overlays/blob/master/examples/spi-mcp251x.dts

What else do I need to do to make the mcp2515 module work?
