Re: [U-Boot] standalone application for ppc internal registers access

Hi eija_flight,

I am using GCC inline assembly in standalone applications to access my cpu (ppc) internal registers. And it seems some of the registers were needed by U-boot to run, because when I am accessing some of these registers via standalone applications, the board will go reset or hangs.

Is there any method to avoid this reset/hangs matter and peacefully back to U-boot after exiting the standalone applications? because I need to use each of registers, respectively.

There once was the extraordinary idea of saving registers before usage and restoring them on exit.

Cheers Detlev
