Why not install Midnight Commander ?

Append followng line to file: Zybo-Z7-10/project-spec/meta-user/recipes-core/images/petalinux-image.bbappend

IMAGE_INSTALL_append = " mc"

Then run petalinux-config -c rootfs and select mc

[Victor]

Hello @lonel,

I have done it  and got the messages:

..............................................................

[INFO] succesfully configured rootfs

Please suggest what necessary to do after that ?

Thank you,

Best regards,
Victor.

I have got the error:

root@victor-System-Product-Name:/home/victor/Zybo-Z7-10# petalinux-build
[INFO] building project
[INFO] sourcing bitbake
INFO: bitbake petalinux-user-image
ERROR:  OE-core's config sanity checker detected a potential misconfiguration.
    Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
    Following is the list of potential problems / advisories:

    Do not use Bitbake as root.

Summary: There was 1 ERROR message shown, returning a non-zero exit code.
ERROR: Failed to build project

 

I do not understand this error.

Please help to do this command without errors.

Best regards,
Victor.

Do not use Bitbake as root.

You stared petalinux-build as root (SUPER USER with full system permissions #).

Do NOT use root user(sudo) casually. Sooner or later you will mess up you system and loose important data.

[Ionel]

Are you familiar with Linux file permissions?

Are you familiar with Linux file ownership?

[Victor]

Error again:

victor@victor-System-Product-Name:~/Zybo-Z7-10$ petalinux-build
[INFO] building project
[INFO] sourcing bitbake
ERROR: Failed to source bitbake
ERROR: Failed to build project
victor@victor-System-Product-Name:~/Zybo-Z7-10$ 

[Victor]

Yes I am familiar with Linux file permissions  and Linux file ownership.

Now I am running this command not under root.

But I have got error again.

Please help to complete this.

Thank you.

find project-spec/ -user root

dose above command has any output?

[Ionel]

Please attach Zybo-Z7-10/project-spec/meta-user/recipes-core/images/petalinux-image.bbappend file

 

[Victor]

No.

It seems as command hangs.

 

[Ionel]

Try remove build and components directories, then run a petalinux-build. If this fails please attach above mentioned file.

[Victor]

I have done it.

Then I erased files   BOOT.BIN  image.ub  from SD   and wrote there new ones. 

Anfortunately loading from the new SD gives  errors.

Please look the file "messages" in the attachment.

Thank you.

it doesn't work anymore in PetaLinux 2020.2 ☹️
I appended to file project-spec/meta-user/conf/user-rootfsconfig
the line CONFIG_mc
then I ran petalinux-config -c rootfs and selected the mc checkbox
when running petalinux-build I get the error:

ERROR: petalinux-image-minimal-1.0-r0 do_rootfs: The postinstall intercept hook 'update_gio_module_cache' failed, details in /project/test/build/tmp/work/zynq_generic-xilinx-linux-gnueabi/petalinux-image-minimal/1.0-r0/temp/log.do_rootfs

note that if I uncheck the mc checkbox it builds and runs fine
I get the same update_gio_module_cache error when I try to build other PetaLinux standard packages that used to build ok before updating to 2020.2

is there any workaround for update_gio_module_cache errors ?

Thanks!
Cris

Hi @Cris ,

Have you tried a clean build after upgrading to 2020.2 ?
If not, try removing everything in build directory except downloads directory. Also remove components directory. Finish work in progress with petalinux-build -c {component} -x finish before removing components directory.
