"K26" is the name of the SOM (System-on-Module). "KV260" is the name of the SOM + Base board.
I am guessing the Base board overlay was applied on Jammy, but not on Focal. I think Jammy is correct. Better to check U-Boot applied the overlay before booting the kernel. BTW, I checked the focal kernel tree, but did not find "K26". Where did that device tree come from? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-xilinx-zynqmp in Ubuntu. https://bugs.launchpad.net/bugs/2021962 Title: F/xilinx and J/xilinx uses different keyword in /proc/device- tree/compatible Status in ubuntu-kernel-tests: New Status in linux-xilinx-zynqmp package in Ubuntu: New Bug description: While testing J/xilinx, I noticed that the keyword we use to grep from /proc/device-tree/compatible has to be changed into kv26 instead of k26 that we used for F/xilinx J/xilinx: $ cat /proc/device-tree/compatible xlnx,zynqmp-sk-kv260-rev1xlnx,zynqmp-sk-kv260-revBxlnx,zynqmp-sk-kv260xlnx,zynqmp F/xilinx: $ cat /proc/device-tree/compatible xlnx,zynqmp-smk-k26-rev1xlnx,zynqmp-smk-k26-revBxlnx,zynqmp-smk-k26-revAxlnx,zynqmp-smk-k26xlnx,zynqmp From what I can found on the Internet, KV260 is "a vision application development platform for Kria K26 SOMs (system-on-module)". But it's better to let the kernel maintainer (Portia) to answer that if this difference is expected.
