Subject: MX28 & finding out boot mode
Date: Thu, 30 Aug 2012 10:25:18 +0200	[thread overview]
Message-ID: <20120830082518.GA27306@pengutronix.de> (raw)

Hi,

is there a way to find out how the MX28 was booted? I could read out the
bootmode-pins for indication. Still, either by button or by empty NAND,
the CPU could have been booted via USB recovery mode. And going through
the docs and the bootlets code, I can't find a way to determine if USB
recovery was used.

So, can USB recovery mode be detected somehow? Then, this and reading
pins should be sufficent, no?

Thanks,

   Wolfram
