Bug ID: 15191
Summary: pc_x86_64_efi_defconfig doesn't run on real hardware
Product: buildroot
Version: 2022.08.1
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]Target Milestone: ---
I have been trying to get a Buildroot image to run on an x86_64 machine but I'm not having much luck. The generated image boots fine on QEMU but if I try to run it on real hardware, I just get a blank screen after the GRUB menu.
I have tested running on a couple of different machines with the same result and have confirmed that I can boot a standard Linux distro on the target hardware successfully.
# Steps to reproduce
git describe:
2022.08.1-38-b44e2cf19a
make clean && make distclean
make pc_x86_64_efi_defconfig
make -j(nproc)
# Running in QEMU (works)
qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd -drive format=raw,file=output/images/disk.img -m 4096M
# Running on Hardware (doesn't work)
* Flash image to USB stick
* Boot from USB stick
* UEFI works
* GRUB menu displayed
* Select boot option
* Blank screen, no further progress

--- Comment #1 from Thomas Petazzoni <[email protected]> --- Could you give more details about what hardware you are using, especially which CPU you have ?

Resolution|--- |FIXED--- Comment #2 from Sam Bristow <[email protected]> --- Sorry for the delay in replying. I tested this on a couple of different machines, an Elkhart Lake Atom board and a random other intel box from around the office.
I think the issue was that I wasn't getting a framebuffer to display anything after grub.
Now that the EFI framebuffer is enabled by default the pc_x86_64 config works out of the box.
