Subject: NVRAM access on Raspi
Date: Mon, 10 Aug 2020 20:14:12 +0200	[thread overview]
Message-ID: <20200810201412.3bcc6b9d@gmx.de> (raw)

Hello,

after I finally managed to get a Raspberry running some more than the
original install image, a few more problems arise.

When trying to auth/wrkey I only get an error that accessing the nvram
is to an unknown device. src auth/nvram shows me that only readnvram()
is called there, but the man page doesn't even mention arm systems, and
what's stated there seems to indicate that the correct location,
/dev/sdM0/nvram isn't even tried.

So is there a trick to work around that? Could I simply dd to the
device, if I knew the correct format (I still don't) or bind /dev/sdM0
to /dev/sdC0 or the like?

Another point: as I have an SD card larger than the decompressed SD
image, how is it possible to expand the HJFS (or at least be able to
use the rest as file system space)?

Thanks in advance && best regards
Eckard
