please note, same hardware(jetson), I used the 4.6.1 version before, which spi is working, but not stable, but after I update to 4.6.4, then spi is not working anymore, even I go back to 4.6.1, still not working.
I justed checked with Yahboom engineer, they also tried on their own jetson nano b01, the spi is nor working in loop back mode.
Could you please help check on your side, 4.6.1 or 4.6.4, any is ok, if it’s working or not?
If it’s working with some modification needed, could you please help prapare a shell script or something similar that user can easily do the changes, or you can share the correct dts/dtb file?
Because we are application developer, we really don’t have much know-how on linux device driver/ device tree staff.
All we need is a clear step on what ever jetson pack, to make the SPI and mcp2515 working, could you please help check and support to provide a detial guideline, thanks.
