Yes, but only the first 4K is used. What’s needed is to check whether or not the rb_hardconfig driver will successfully process a 4K-only block from an 8K partition. I *think* it should, but haven’t looked back at the code or tested that yet. If that’s the case then adapting routerbootpart is relatively trivial. > Note that the device for which I have the issue is an "old" one from 2019, > it's still using a single tag for the ERD data (LZO + RLE). > > I'll send a RFC patch to give an idea of the change I have in mind (there > are a few more changes needed than just setting the size in the DTS). > >> Can you provide me with a dump of the Routerboot partition? >> >> I’ll take a look at what can be « sanely » done. > > Sure, here it is. Thanks, I’ll take a look soon.
