CM5 and LetsTrust TPM with u-boot and Linux

Hi, I'm working on getting Raspberry Pi CM5 with a source kit io board and LetsTrust TPM with u-boot and Linux working. I'm building a custom u-boot similar to the description here:  https://github.com/joholl/rpi4-uboot-tpm/blob/ad31306ce2f2d52f0572385bfc8bac33cb1f1f68/README.md#setting-up-and-con

Raspberry Pi Compute Module 5 support

Hi, I'm trying to boot openSUSE Linux on an CM5 using a sourcekit io board (https://sourcekit.cc/#/). u-boot seem to be stuck with the logo on the upper right corner, no text. I re-built u-boot using the latest source from git from the next branch and also set CONFIG_LOG in make menuconfig, but sti

Re: u-boot on raspberry pi with secure boot

Hi, I have produced a signed linux UKI image. But I need to build u-boot to only allow booting with the signed certificate. So I need a ubootefi.var for (EFI_VAR_SEED_FILE) according tohttps://github.com/u-boot/u-boot/blob/ee2af844ba1b27b2e959c4e649e4b769fbeb4074/lib/efi_loader/Kconfig#L146 How

u-boot on raspberry pi with secure boot

Hi, I have a custom installation of openSUSE Tumbleweed which uses u-boot and Grub. To use secure boot on the RPI, one creates a boot.img containing the kernel and other files which is signed, and the eeprom is locked to only allow booting with this signature. (https://github.com/raspberrypi/usbbo

silent u-boot not working

Hi, I'm running openSUSE Tumbleweed on an RPI CM4, I'm trying to silence u- boot boot messages, with the default configuration there is an u-boot logo on the top right corner and boot text, I'd like to get rid of the logo and all text if possible. The keyboard is not working before the Linux kerne

TPM setup on a RPI Compute Module 4

Hi, I have a CM4 with a sourcekit io board and a pi3g lets trust TPM. It's running Raspberry Pi OS Bookworm. tpm2_pcrread shows zeros for all pcr's. My understanding is that the tpm needs to be setup on boot so the pcr values are populated. So how can I best fill in the values for the TPM?
