Yes, you can track this down. Just locate the .dll file referenced in the above register dump (well, in fact, the same pathname with the .debug suffix might be even better), and then with the help of "objdump", you can tie the crash site to the source code: http://thread.gmane.org/gmane.comp.bios.tianocore.devel/7300/focus=7305 Thanks Laszlo > > Note that on qemu the coreboot hardware initialization is alot simpler > than on real hardware, so it could simply be that CorebootPkg expects > some information from coreboot which simply isn't there in the qemu > case. > > Given that CorebootPkg seems to crash in cpu initialization you might > want to have a look at the very simple coreboot cpu driver for qemu, in > src/cpu/qemu-x86/ > > cheers, > Gerd > > ------------------------------------------------------------------------------ _______________________________________________ edk2-devel mailing list edk2-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/edk2-devel
