Hi @rdunkle !
Works with U-Boot v2025.10 and OpenSBI higher than v1.7 for me:
U-Boot SPL 2025.10 (Nov 06 2025 - 07:48:41 +0100)
DDR version: dc2e84f0.
Trying to boot from MMC2
OpenSBI v1.7-71-g38a6106

With OpenSBI version 1.7, when building with FW_START_ADDR, the parameter will be ignored. So it defaults to address 0x0 instead of 0x40000000 which raise an exception. That’s might be a bug. But with the current sources in the main/master branch from OpenSBI it works.
Hope this helps.
