On the U-Boot side, it's being looked in to. In fact, you're saying v2025.04 is working (current release) and v2025.07-rcX is failing. At this point in the U-Boot cycle I think we'll figure out the problem and fix it. If we can't figure out how to keep all the use cases working for v2025.07 then disabling BLOBLIST here in OE can be thought on, I would expect.
