Previously, the UART output stopped right after switching to a 64-bit core. Now I am getting some further messages, but nothing for the 64-bit U-boot itself: U-Boot SPL 2026.01 (Apr 18 2026 - 14:03:05 +0000) SYSFW ABI: 4.0 (firmware rev 0x000c '12.0.2--v12.00.02 (Clever Cat)') Changed A53 CPU frequency to 1400000000Hz (T grade) in DT SPL initial stack usage: 13416 bytes Trying to boot from MMC2 Authentication passed Authentication passed Authentication passed Authentication passed Authentication passed Starting ATF on ARM64 core...

I pointed both the 32-bit and the 64-bit U-boot build to it via the BINMAN_INDIRS variable. I am using the most recent OPTEE (tag: 4.10.0) and TF-A (dated April 9). Initially I was copying the file tiboot3.bin from my build container. I tried to mimic your script and switched to copying tiboot3-am62x-hs-fs-evm.bin instead (named tiboot3.bin on the MicroSD card), but it did not make any difference to the above output. The U-boot source I am trying to build is your clone ef03e35488377a32cdd4f76d1a03ef7f60c798ef (January 30). Can you give any hint where it could be stuck or how to enable the UART output in U-boot? As far as I can tell, my build is passing similar options to the U-boot build as yours, with the main one being am62_pocketbeagle2_*_defconfig. I'm editing a build script that was working for the PHYTEC phyBOARD Lyra. I see that your script is setting CONFIG_BOOTCOMMAND in the USB DFU version. I am attempting to build the normal version. With best regards, Marko
