Hello, some clobbering could indeed be the source of the problem, though I currently fail to see why that would happen. When running the objdump dance on the working u-boot 2022.10, this gives me the following address blocks: 0x802001a4 0x80200e60 0x80259bbc 0x80275a38 0x802769d1 0x802770c8 0x802778b8 0x80283d60 0x80283e70 0x80284628 0x80287f88 0x80288138 0x8029c2b0 0x8029d9a8 0x802a8008 On the non-working u-boot 2023.01 that is in unstable since today this gives me 0x802001a4 0x80200e70 0x8025a604 0x802762f4 0x802772e8 0x802779ec 0x802781f4 0x802847a8 0x802848b8 0x80285098 0x80288a08 0x80288bb8 0x8029cf40 0x8029e6b0 0x802a8d08 i.e. the used area is a little bit larger in the non-working case, but still way below one MB. On the other hand OpenSBI's ./platform/generic/config.mk contains FW_JUMP_FDT_ADDR=$(shell printf "0x%X" $$(($(FW_TEXT_START) + 0x2200000))) i.e. AIUI it reserves an area of 0x2200000 bytes (34MB) for it's payload, so there should be plenty of space and no clobbering should occur. I've also taken a look at the u-boot changelogs and there have been quite a few changes concerning u-boot's handling of device-trees between the working and the non-working versions. Unfortunately I'm not familiar enough with the inner workings of u-boot to understand the implications of several of these changes.
