This makes mass production more ease and doesn't produce hight costs :) Dieter > > > > I'm willing to contribute some code if someone guides me a bit? > > > > You are most welcomed.... > > Pls feel free to raise your queries... > > Here they are :) > Thanks, > Dieter > > > Regards.. > > Prafulla . . > > > > > Thanks in advance, > > > Dieter > > > > > > _______________________________________________ > > > U-Boot mailing list > > > U-Boot@lists.denx.de > > > http://lists.denx.de/mailman/listinfo/u-boot > > _______________________________________________ > U-Boot mailing list > U-Boot@lists.denx.de > http://lists.denx.de/mailman/listinfo/u-boot _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
