Hi Bin, I am putting down the steps below as to how to debug u-boot bare-metal on qemu.
*git clone git://git.denx.de/u-boot-x86.git <http://git.denx.de/u-boot-x86.git>cd u-boot-x86export BUILD_ROM=ymake qemu-x86_defconfigmake allqemu-system-i386 -nographic -bios u-boot.rom -net nic -net user,tftp=/tftpboot* We will have a u-boot prompt at this instance as shown below. *=>Terminal-* *U-Boot 2015.07-rc1-20475-g257e98e (May 13 2015 - 23:35:32)CPU: x86, vendor Intel, device 663hDRAM: 128 MiBUsing default environmentVideo: 640x480x16Model: QEMU x86SCSI: controller reset failed (0x1009)scanning bus for devices...Invalid port number 1Found 0 device(s).Net: e1000: 52:54:00:12:34:56 e1000#0Warning: e1000#0 using MAC address from net device* In order to boot Linux, the kernel image and rootfs should be present in the /tftp directory. Note /tftpboot is the root directory for QEMU's tftp server. You will need to setup U-Boot network environment variables before 'run ramboot' to boot linux. *#u-boot> dhcp* *#u-boot> run ramboot* Regards, Saket Sinha On Sun, May 24, 2015 at 7:54 PM, Bin Meng <bmeng...@gmail.com> wrote: > Hi Saket, > > On Tue, May 5, 2015 at 10:11 PM, Saket Sinha <saket.sinh...@gmail.com> > wrote: > > Hi, > > > > I am trying to run u-boot as a coreboot payload on qemu-x86.Currently > > facing some difficulty in the process. > > > > Has anyone tried running u-boot bare-metal or as a coreboot payload on > > qemu-x86 before? > > > > Reply this thread for completeness in case someone else wants to try > U-Boot on qemu-x86. > > The latest U-Boot git repo > (http://git.denx.de/?p=u-boot/u-boot-x86.git;a=summary) contains > U-Boot bare-metal support for QEMU x86 targets (i440fx and q35), as > well as being loaded from coreboot. > > Regards, > Bin >
