Altera Angstrom on jffs2 Init boot

Hello guys,

I am trying to run my own scripts on Angstrom after boot.

I figure out here I cant use the /etc/init.d but I has to use systemd services.

So I create my own systemd service

$ cat /lib/systemd/system/my_script.service

Description=Setting environment after boot

ExecStart = /etc/init.d/ start


So I run to enable this service:

$ systemctl enable my_script.service

And I get This Error:

$ systemd-gpt-auto-generator[259]: Failed to verify GPT partition /dev/mtdblock3: Invalid slot

I am running Angstrom on NOR Flash with jffs2.

Does Any one has any Ideas How to Start My own scripts after Angstrom boot-up?

Thank You for all info.
