tftp boot of lsdk2004_ubuntu_main_LS_arm64.itb

[karlgilkey]

I used flex-builder to build lsdk2004_ubuntu_main_LS_arm64.itb 
I am able to tftp the file in uboot but I an error when the kernel boots. 

This is how I am attempting to boot:
setenv bootargs 'console=ttyS0,115200 root=/dev/ram0 earlycon=uart8250,mmio,0x21c0500 earlyprintk' 

bootp 0xA0000000 169.254.0.100:lsdk2004_ubuntu_main_LS_arm64.itb 
bootm 0xA0000000#ls1046afrwy

Is there an issue with my bootarg? Why is this error happening.

[karlgilkey]

Thanks I have managed to build and boot ubuntu:lite and yocto:tiny.

I have tried adding additional packages to the file system of both images with no luck.

I need to add the nfs helper files. I tried to add nft-utils as an additon package. I don't see any change to the filesystem

In the end I also need to add Python3 as well. 

I added the packages to additional_lite_packages_list

and the local_arm64_tiny.conf but don't see a change. What do I need to rebuild.

[yipingwang]

Please add "nfs-common" to "additional_lite_packages_list" in configs/ubuntu/additional_packages_list 

Then execute the following command.

$ flex-builder -i clean-rfs -r ubuntu:lite

$ flex-builder -i mkrfs -r ubuntu:lite

$ flex-builder -i packrfs -r ubuntu:lite

[karlgilkey]

So I am able to build and boot using buildroot:tiny.

How do I add packages to a buildroot filesystem?

When the build root image boots it does not bring up the network interface via dhcp. What do I need to change to get that to work on boot.

[yipingwang]

1. add new “BR2_PACKAGE_NFS_UTILS=y” in configs/buildroot/qoriq_arm64_tiny_defconfig

2. rebuild it

$ flex-builder -i clean-rfs -r buildroot:tiny

$ flex-builder -i mkrfs -r buildroot:tiny

I am runing flex-builder in a virtual box vm on a Windows 10 host.

When I run: flex-builder -i mkrfs -r ubuntu:lite 

It fails with this error.

gpgv: Good signature from "Ubuntu Archive Automatic Signing Key (2012) <ftpmaster@ubuntu.com>"

I believe this is an error running qemu? Should I expect flex-builder to run in a VM?

According to your following log, it seems that you didn't download the rootfs filesystem completely. As normal, the date size of ramdisk Image should be 600-700M.

   Trying 'initrd' ramdisk subimage

     Description:  initrd for arm64

     Created:      2021-03-23  22:10:05 UTC

     Type:         RAMDisk Image

     Compression:  uncompressed

     Data Size:    138956800 Bytes = 132.5 MiB

     Architecture: AArch64

 You could regenerate the itb image with the following procedure.

$ flex-builder -i clean-rfs

$ rm packages/rfs/initrd/rootfs_lsdk2012_ubuntu_main_arm64.cpio.gz

$ flex-builder -i mkitb -r ubuntu:main -a arm64

In addition, the ubuntu:main rootfs is too large to run on LS1046AFRWY, you could use Ubuntu-based lite rootfs filesystem(Include Ubuntu 18.04 base packages and part of NXP's packages), it is about 180M, you could generate the itb image with the following command.

$ flex-builder -i mkitb -r ubuntu:lite -a arm64

Now I am having problems build ubuntu:lite

I am running flex-builder in a virtual box vm instance of Ubuntu 18.04

When I try to run

flex-builder -i clean-rfs -r ubuntu:lite -a arm64
flex-builder -i mkrfs -r ubuntu:lite -a arm64

I goes all along and runs into this error.
