Hello I have successfully built u-boot and launched qemu with the flags proposed by the patch. My problems start when I try to boot the kernel What is the linux kernel defconfig that should be used to boot this machine? I tried the versatile one but they are different in some key places like the sd card. The end result is that I can only see Starting Kernel, and nothing else. What bootargs do you pass to the kernel to have the serial output in qemu? Paulo Neves ___ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot

Since qemu-x86 is put there.

[U-Boot] [PATCH 2/2] ARM: Add a new arch + board for QEMU's 'virt' machine
This board builds an U-Boot binary that is bootable with QEMU's 'virt'
machine on ARM. The minimal QEMU command line is:
qemu-system-arm -machine virt,highmem=off -bios u-boot.bin
(Note that the 'highmem=off' parameter to the 'virt' machine is required for
PCI to work in U-Boot.) This command line enables the following:
- u-boot.bin loaded and executing in the emulated flash at address 0x0
- A generated device tree blob placed at the start of RAM
- A freely configurable amount of RAM, described by the DTB
- A PL011 serial port, discoverable via the DTB
- An ARMv7 architected timer
- PSCI for rebooting the system
- A generic ECAM-based PCI host controller, discoverable via the DTB
Additionally, QEMU allows plugging a bunch of useful peripherals to the PCI bus.
The following ones are supported by both U-Boot and Linux:
- To enable a Serial ATA disk via an Intel ICH9 AHCI controller, pass e.g.:
-drive if=none,file=disk.img,id=mydisk -device ich9-ahci,id=ahci -device
ide-drive,drive=mydisk,bus=ahci.0
- To enable an Intel E1000 network adapter, pass e.g.:
-net nic,model=e1000 -net user
- To add an EHCI-compliant USB host controller, pass e.g.:
-device usb-ehci,id=ehci
