Then how we supposed to switch the POST_SLOWTEST mode? Is the proprietary HW button scanning implemented in post_hotkeys_pressed() of some boards contradicting with "NOT interactive" claim? > In such an envrionment, handling of ^C makes no sense.

Ok, at least in the ppc branch the interactive input is available before the first POST ROM test is executed. >> The value of ctrlc_disabled variable defined as static in the console.c >> file is lost after code relocation. > > Actually you cannot modify it before relocation. Correct, so I added it to the global data structure in such a way that its size was not affected. > >> By adding the ctrlc_disabled to global data gd structure the problem was >> solved. > > It makes no sense to add all sort of random data to gd. gd should be > kept strictly minimal. Agree, the structure should be as small as possible. Please read the question #2 of my original posting where I addressed this issue. > Best regards, > > Wolfgang Denk Thanks, Michael _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
