You may have to press them a while, just before the init message comes. I.e. approx. 5 seconds after booting. What I have found in addition is that the /proc/powerdown does not work anymore. But this may be due to a different PIC in my two machines. The bricked one did immediately switch on the LCD while the other one keeps the screen black for approx. 1 second. So I assume that this is the PIC. And, it may communicate differently (there are #ifdefs in the source file). Maybe, we can find a way that the driver applies both methods (because I don't know how to detect the PIC version).

What I really don't understand why a fresh yaffs2 already puts aside approx. 2 of the 5 MByte even *after* flash_erase which should wipe out any debris from jffs2... > > So far this kernel 2.6.24.3 and the updated sources are very usable now. ;-) > > Grt Ruben. > > > > Subject: Re: [Mipsbook-devel] yaffs2 > > From: h...@computer.org > > Date: Wed, 16 Jun 2010 08:44:33 +0200 > > CC: r_vi...@hotmail.com; mipsbook-devel@linuxtogo.org > > To: h...@computer.org > > > > > > Am 16.06.2010 um 08:31 schrieb Dr. H.
