hi, yes i did this added https://www.element14.com/community/community/project14/visionthing/blog/2019/11/16/beagleboard-ai-brick-recovery-procedure
performed To enable it set a line in the /boot/uEnv.txt: + expand source <https://www.element14.com/community/community/project14/visionthing/blog/2019/11/16/beagleboard-ai-brick-recovery-procedure#>view plain <https://www.element14.com/community/community/project14/visionthing/blog/2019/11/16/beagleboard-ai-brick-recovery-procedure#> 1. dtb = am57xx-beagleboneai-roboticscape.dtb 2. when i did that , beagle bone doesnt boot up. hence i reflashed the fresh image and reverted all changes to the boot file. Updating the device tree Out of the box the BBAI pins do not support the SPI bus. So why not? To fix this one has to edit the device tree. Checking under boot/dtb where the compiled device tree file are shows there are 2 dtb for BBAI. One is for the plain BBAI, the other for BBAI robotics cape. To make sure I checked the dts file on github which confirms that the vanilla DTB on the BBAI does not have any configurations for the SPI bus. After overwriting the BBAI with the BBAI robotics cape .dtb and rebooting there are now two SPI busses available as shown on the photo below.
