MCP2515 can't receive data

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

But when i candump can0, nothing shown
Any helps will be appreciated. Thank you

hello alfanrizaldy,

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

I’m sorry, my problem is with can0 which is successfully initialized but when i candump can0, it doesn’t shown anything. And i’m not using can1

try to refresh your network settings
