Ideally, your U-Boot port should set the correct value for port config. If you are unable to modify U-Boot, then you can clone arch/powerpc/platform/52xx/mpc5200_simple.c for the tqm5200 board and put the port_config fixup in there. arch/powerpc/platform/52xx/lite5200.c exists for the exact same reason. Look at the lite5200_fix_port_config() function. g. > > BR, > > Jani Särkijärvi > > -----Original Message----- > From: Juergen Beisert [mailto:[EMAIL PROTECTED] > Sent: 19 September 2008 16:58 > To: linuxppc-embedded@ozlabs.org > Cc: Särkijärvi, Jani > Subject: Re: TQM5200 I2C Second bus > > On Freitag, 19.
