Hello, I want to integrate the Beaglebone AI with the Xavier AGX bus using CAN interface. I am using “MCP2515 CAN Bus Breakout Board With SPI Interface” for this. The JetPack version I am using is 4.4. Can anyone please help me with the steps to enable the SPI interface on Xavier AGX board? Thanks…

You need to replace the Image to apply the customized kernel Image too. spidev_test -s should be able to set the speed.

Have a reference to below link for SPI pin configure. [image] SPI1 not work on Xavier Jetson AGX Xavier I enable the spi1 and add spidev device node in dts. I can find the /dev/spidev0.0, but I can’t detect the signal with Logical Analysis. So, I want to kno…

“Please modify the pinmux for spi1 like spi2 does. file name: tegra19x-mb1-pinmux-p2888-0000-a04-p2822-0000-b01.cfg” I cannot find the tegra19x-mb1-pinmux-p2888-0000-a04-p2822-0000-b01.cfg in the BSP source code.

The cfg file gen by the sdkmanager. Please download the sdkmanager to check it.

Thanks for the update. I have applied the Rt linux patch to make the kernel real time. I did this by downloading the BSP source code (on Nvidia AGX board)and then compiling the kernel image using Rt linux patch. How can I flash the Jetson xavier with RT linux patch and the SPI interface enabled?

Have a check below link to update the dtb and just replace the /boot/Image for the customized kernel Image.

Hi Shane, I don’t see the link. Are you referring the link you posted earlier?

Sorry, Please check below link. https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fkernel_custom.html%23

I did the pinmux configuration for the SPI1 device. What are the steps to create the corresponding device tree file? Should that be done on host machine or target Nvidia device? I found this post to modify the device tree [image] ADC using SPI on Xavier Jetson AGX Xavier …

The reference link is update the cfg file and update the image from host machine. download skdmanager. Using sdkmanager to download and install the image. Modify the cfg file that gen by the sdkmanger. You can find the path from the sdkmanager GUI modify the cfg file flash the Image again.
