MCP2515 can't receive data

[alfanrizaldy]

Hi, i’ve already followed some tutorials to interfaces the MCP2515 modules.
https://forums.developer.nvidia.com/t/unofficial-guide-to-using-the-mcp2515-can-module-on-the-jetson-nano-2gb/208818

The tutorial can help me until successfully initialized, but the data doesn’t shown. Here my configuration pin

|INT|31|
|SCK|23|
|SI|19|
|SO|21|
|CS|24|
|GND|GND|
|VCC|5V|

and this is my log

Any helps will be appreciated. Thank you

mcp251x: probe of spi1.0 failed with error -16

hello alfanrizaldy,

there’s probing failure.
please review your hardware wiring and also driver chagnes.
