Thanks Marek and Biju. The current state is still that people will take the forked Renesas TF-A, the mainline U-Boot with the renesas_rzg2l_smarc_defconfig configuration and expect things to work out of the box. Currently, before figuring out that the TF-A needs to be patched manually, U-Boot is just crashing without outputing anything, which is painful to debug. As the only RZG2L supported by U-Boot is the r9a07g044l2-smarc, and we are not receiving any blob from the TF-A, I think it is fair to assume that we are booting from the platform we are compiling U-Boot for. I have proposed a patch here: https://lists.denx.de/pipermail/u-boot/2025-September/598712.html Thanks, Mathieu
