So I rebuilt the image, applied a patch to integrate the tpm into the dts during the build and it works. I still need to figure out how to make overlays work with GRUB in case we need them. Thank you for your support

Hello, Thank you for your answers. I decided to recompile the whole image with the correct configuration to be sure I did not mess up anything when updating my kernel (following this https://github.com/armbian/build/commit/54c896e0298a441338cd7d29f312ca590304f120 , using BRANCH=vendor RELEASE=noble) I was able to get the boot logs (see attached file). It seems since I'm using UEFI it completely bypasses the U-Boot applying the overlays ( i can see EFI stub: Using DTB from configuration table inside the logs but no Applying device tree overlay...) . I'll try to recompile the image while integrating my overlay directly into it to see if it works. boot.logs

Hello, I've been using https://joshua-riek.github.io/ubuntu-rockchip-download/boards/orangepi-5-plus.html with a custom kernel that I built to activate my TPM2.0 device and it works. Now I'm asked to use an UEFI compatible image with my Orange Pi 5 Plus. So what I did is more or less the same thing that in here But instead of the legacy kernel I used the 6.1.115-rockchip-vendor-rk35xx kernel and my device booted, I got an HDMI output, etc. And then I updated it to my custom kernel (6.1.0-1027-rockchip) that has the necessary configurations to allow TPM over SPI. Now I'm trying to activate my TPM2.0 as I did before. To do that I added my compiled *.dtbo (rk3588-spi0-tpm-cs1.dtbo) to /boot/dtb/rockchip/overlay and activated it with armbian-config. After reboot this is my /boot/armbianEnv.txt orangepi@uefi-arm64:~$ cat /boot/armbianEnv.txt verbosity=1 bootlogo=true console=both extraargs=cma=256M overlay_prefix=rk3588 fdtfile=rockchip/rk3588-orangepi-5-plus.dtb rootdev=UUID=3e555b58-fdf4-4e2f-a3af-a8ecfd8034b6 rootfstype=ext4 overlays=spi0-tpm-cs1 param_spidev_spi_bus=0 However I still can't see my tpm under /dev/. I don't know what I'm missing, I'm quite new to this sorry Thank you for your time
