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
