Subject: [pasemi] problem with i2c-pasemi
Date: Mon, 1 Aug 2016 11:01:04 +0200	[thread overview]
Message-ID: <dd444219-28f9-4fb9-a258-5131695abba1@xenosoft.de> (raw)
In-Reply-To: <20160801073227.GA1691@katana>

Hello Wolfram,

Many thanks for your explanation. Olof knows the PASEMI platform very 
well. Maybe he could explain more. Adrian has also a good knowledge 
about the Nemo board.

Cheers,

Christian
