Running self-build image on QEMU arm64

[AlexK]

Hi!

 

Currently try to figure out how to run my freshly builded Armbian using QEMU arm64.

According to this tutorial: https://docs.armbian.com/Developer-Guide_Build-Preparation/  I prepare clean Jammy VM.

Build using this CMD: 

./compile.sh BOARD=qemu-uboot-arm64 BRANCH=current RELEASE=bookworm

 

Build process was going smoothly i pick up two files from output folder: 

1) Armbian-unofficial_24.5.0-trunk_Qemu-uboot-arm64_bookworm_current_6.6.29_minimal.img.qcow2 2) Armbian-unofficial_24.5.0-trunk_Qemu-uboot-arm64_bookworm_current_6.6.29_minimal.u-boot.bin

 

Currently boot up process stucked, i can run U-boot and mount qcow2 image using this CMD:

qemu-system-aarch64 \
-machine virt -cpu cortex-a57 \
-netdev user,id=net0 -device e1000,netdev=net0 \
-serial stdio \
-bios Armbian-unofficial_24.5.0-trunk_Qemu-uboot-arm64_bookworm_current_6.6.29_minimal.u-boot.bin \
-drive if=none,file=Armbian-unofficial_24.5.0-trunk_Qemu-uboot-arm64_bookworm_current_6.6.29_minimal.img.qcow2,id=mydisk \
-device ich9-ahci,id=ahci \
-device ide-hd,drive=mydisk,bus=ahci.0

 

U-boot see the drive with rootfs, but during boot process i had this error:

Failed to load '/boot/uInitrd'
Wrong Ramdisk Image Format
Ramdisk image is corrupt or invalid
Boot failed (err=-14)

Any ideas what i'm doing wrong?

The problem was with -m flag, i forget to allocate enough memory for VM to start, so working CMD:

qemu-system-aarch64 \
-machine virt -cpu cortex-a57 -m 512 \
-netdev user,id=net0 -device e1000,netdev=net0 \
-serial stdio \
-bios Armbian-unofficial_24.5.0-trunk_Qemu-uboot-arm64_bookworm_current_6.6.29_minimal.u-boot.bin \
-drive if=none,file=Armbian-unofficial_24.5.0-trunk_Qemu-uboot-arm64_bookworm_current_6.6.29_minimal.img.qcow2,id=mydisk \
-device ich9-ahci,id=ahci \
-device ide-hd,drive=mydisk,bus=ahci.0
