If that's what you mean, then I already have DEBUG_LL, but that doesn't answer my question, as DEBUG_LL stops spitting logs after the decompressor, and the errors I want to trap are between end of decompressor and drivers probe. And my question about earlycon remains, DEBUG_LL is not earlycon. Cheers. -- Robert
