I have a question about those binaries provided in Recovery package, such as cmnlib.mbn, emmc_appsboot.mbn, gpt_main0.bin, patch.xml, etc.
I understand those are proprietary and needed for some low level things, but I am not clear about how they affect the system configuration.
We use one of the D820 SOMs. We were struggling to re-configure a BLSP, then the SOM vendor provided us a different set of binaries, and then it worked.
This was a surprise, because my understanding was, BLSP could be configured by Device Tree and/or kernel patch, but it doesn’t look like that way.
I am still puzzled, but does this sound correct? To re-configure BLSP, you need to change something in those binaries in addition to DT/kernel change.
Sorry for an obscure question and thanks,
