Hooray, changing SYS_CAR_ADDR to 0x1 in arch/x86/cpu/qemu/Kconfig does the trick. Bin, what do you think about it? Best regards, Anton Gerasimov On 11/10/2017 06:25 PM, Anton Gerasimov wrote: > Yes, apparently 0xdfffc is in ROM area for QEMU (0xc -- 0xe, > defined in include/hw/loader

Re: [Qemu-devel] [U-Boot] Support of latest qemux86-64

Yes, apparently 0xdfffc is in ROM area for QEMU (0xc -- 0xe, defined in include/hw/loader.h). The next thing to figure out is why u-boot uses it as a stack area. Best regards, Anton Gerasimov On 11/10/2017 06:04 PM, Anton Gerasimov wrote: > New guess: > > in the most safe configuration of

New guess: in the most safe configuration of u-boot (CONFIG_SMP=n, lacpi disabled) with Igor's patch applied `qemu-system-i386 -bios /path/to/uboot.rom` fails on the first 'ret' instruction. GDB shows that memory at $esp (0xdfffc at the entrance to board_init_f_mem) and everything around it is zer
