I'm trying to run linux arm64 kernel on fast model. I followed the page https://wiki.linaro.org/HowTo/BuildArm64Kernel
After all steps, I had got linux-system-foundation.axf and linux-system.axf.
then I use command as below:
The console complained that I didn't indicate a right root path. I had download the pre-built root filesystems
from Linaro Releases, But I don't know how to use it.
Cound anyone help me? thank you!
----
VFS: Cannot open root device "vda2" or unknown-block(254,2): error -6
Please append a correct "root=" boot option; here are the available partitions:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(254,2)
Call trace:
After all, I had find a solution:
model_shell \
cadi_system_Linux64-Debug-GCC-4.1.so \
linux-system-foundation.axf \
-C motherboard.virtioblockdevice.image_path=block.img
But still I want to use mmc parameter..
Assuming your model is based on the FVP_VE platform with a single cluster, you need to use the img.axf from Linaro Releases , instead of the img-foundation.axf if you want to use the MMC instead of the VirtioBlockDevice.
In this image, the bootargs are set to use the filesystem from the MMC (root=/dev/mmcblk0p2 instead of /dev/vda2)
The MMC model does not support images larger than 2GB, so you would not be able to use some of the pre-built filesystem images from Linaro with it, you would need to follow the instructions to rebuild a filesystem image (from the same page) and use linaro-media-create --dev fastmodel --output-directory fastmodel --image_size 2000M --hwpack <hwpack filename> --binary <rootfs filename>
linaro-media-create --dev fastmodel --output-directory fastmodel --image_size 2000M --hwpack <hwpack filename> --binary <rootfs filename>
with --image-size smaller than 2GB
