Hey I want to communicate with my jetson nano and mcp2515 can module over spi. I have read a lot of guides, but with no luck. can anyone give me a step by step guide from scratch Thank you

Hi xudonglei2020, I have a working dts file modified from Linux_for_Tegra and Seed-Studio’s MCP implementation. I got it working on my Jetson Nano with an MCP2515 board from Joy-It (SBC-CAN01) running a 16 MHz oscillator. Feel free to try it. To use: Clone the Seeed-Studio github repository as st…

GPIO07(168) and GPIO11(200) are just the names of pins on SODIMM connector.

If you do not have oscilloscope but have some other device (ex. multimeter), can you tell me if INT pin is going low on the MCP chip when you send the message from MCP?

Hi shgarg, I will measure and inform you. But for god result I don’t have analog multimeter. The other situation is I download the source code for JP4.5 and check the mcp251x.c file.The patches which you give us was not implement on the driver file. I change the source code according your patch fi…

Why are you applying the patches? You do not need to modify driver. DTB is already present , just run with jetson-io

The new develeoper kit is not same as previous one. https://developer.download.nvidia.com/embedded/L4T/r32-3-1_Release_v1.0/Jetson_Nano_Developer_Kit_User_Guide.pdf?nxWSAnHlLttZWf06L5-hfMiBj4S4fXAnLsigT4QCsuoYV_OXLAIIj8NbFvzxYbaYGxKX5K5QuqupPE8zFkpRfPlXuADjlbzr63-WxVVrnce5yq71G61uuuQP4DkxWBUjFjc1wHq…

According to new manual my carrier board is B01. It is not A02 or B00. Jetson Nano User Manual When I save the configuration on jetson-io it return me with B00 . Configuration saved to file /boot/kernel_tegra210-p3448-0000-p3449-0000-b00-mcp251x-can-controller.dtb.

Hi Shgarg , Ther is no activitty on CAN H and L pins. It is always 2.65 V . I also check PIN31 interrupt pin and it is always 5.1 V

@ Hi all, with all of your discussion below, i was able to understand some of steps and able to see CAN0 in my network. However, when i run command, ‘cansend can0 123#xyz’ or ‘candump can0’. I do not see any activity. I am sending data continuously through can on Jetson nano. and running candump c…
