Cannot update rootfs on rdb ls2085

[elishemesh]

Hi

I am working on LS2085A ear5.

I would like to add sftp server to the rootfs. I added the line "vsftpd" to "meta-fsl-networking/images/fsl-image-core.bb". After this I made "bitbake fsl-image-core" and then "bitbake fsl-image-kernelitb". In the deploy folder I opened the rootfs and I could find the sftp under "/usr/sbin/vsftpd". However when I down load the kernel.itb to the target (drb) I could not find the file in "/usr/sbin/vsftpd" and the sftp server did not work.

When I opened the file "tmp/work/ls2085ardb-fsl-linux/fsl-image-kernelitb/1.0-r0/kernel-rdb.its", I did not found the rootfs as part of the kernel.itb.

My question is: How can I update the rootfs and what is the correct way to add the sftp server?

Thanks,

Eli.

Hello Eli,

Probably you didn't use the correct file, I verified your procedure, and test the built image on ls2085 board, it works.

Add vsftpd in the recipe meta-fsl-networking/images/fsl-image-core.bb, then execute "bitbake fsl-image-core" and "bitbake fsl-image-kernelitb", after building please use the file "kernel-ls2085ardb.itb" in build_ls2085ardb_release/tmp/deploy/images/ls2085ardb/kernel-ls2085ardb.itb

IMAGE_INSTALL += " \

    gdbserver \

    packagegroup-fsl-core \

    packagegroup-fsl-dpaa2 \

    vsftpd \

"

Please refer to the following boot log on ls2085 target board.

Hello Yiping

Thank you for the quick test.

I tried your suggestion, and even I run the bitbake with the –f option. I copied the file "kernel-ls2085ardb.itb" to the target and I cannot find in target the files:

1. ./etc/init.d/vsftpd

2. ./usr/sbin/vsftpd

However when I opened the file "fsl-image-core-ls2085ardb.tar.gz", that located in deploy, in my x86 linux machine, I found those files.

Please reread what I wrote about the file "tmp/work/ls2085ardb-fsl-linux/fsl-image-kernelitb/1.0-r0/kernel-rdb.its". It looks that it will not work, because the its file do not pack the rootfs to the itb file.

Thanks,

Hello Yiping

Now I can find the sftp server in the target. The problem was that I have to update the kernel.itb when the bank in the rdb is 4. I have to use the command "qixis_reset altbank", in the target, prior to updating the kernel.itb in the u-boot.

However the sftp server did not work because I have to change the line "Subsystem sftp /usr/lib/openssh/sftp-server" to " Subsystem sftp internal-sftp" in file: " work/ls2085ardb-fsl-linux/fsl-image-core/1.0-r0/rootfs/etc/ssh/sshd_config".

The problem is when I run " bitbake fsl-image-kernelitb", the bitbake remove my changes.

What is the correct way to change files in rootfs and then to build with bitbake?

Thanks,

Eli Shemesh

Hello Eli,

The file sshd_config is generated when compiling the package openssh, please use the following method to add your modification into rootfs filesystem.

$ bitbake openssh -c cleansstate

$ bitbake openssh -c compile -f

$ cd build_ls2085ardb_release/tmp/work/aarch64-fsl-linux/openssh/6.7p1-r0/openssh-6.7p1/

Modify the file sshd_config as what you require.

$ bitbake openssh

$ bitbake fsl-image-core

$ bitbake fsl-image-kernelitb

Have a great day,
Yiping
