My statescript start with the following
if [ ! -x /sbin/fw_printenv ]; then
echo “printenv not found” >&2
exit 1
fi

And I get this from my log:

If I go into the directory /sbin the file fw_printenv is there but if I am in home and do ls -l /sbin/fw_printenv it returns that it cannot be found. Does anyone know what is going on here? Thank you for your help :blush:

Hi @davidlekve,

Maybe a couple more details?

  • is the /sbin/fw_printenv binary executable? What is the output of ls -alh fw_printenv while you are in /sbin
  • which OS is this? How did the Mender integration happen?
  • can you drop the output of mount?
  • does the root filesystem update work?

I found out the problem. It never was in sbin, the binary just worked there because then i didnt write a path in front of it… :expressionless: which fw_printenv returns /usr/bin/fw_printenv.

A rookie mistake, but I think I was too locked in on that the binary should be in /sbin because of the example. Sorry to bother you @TheYoctoJester

Just to be sure, do you think there is any problem with changing the path to /usr/bin/fw_printenv or should I instead try to make the yocto project build/move the fw_printenv file in sbin. I am building for the pi5.

Hi @davidlekve,

Great thanks for pointing it out, we definitely should fix the example. Not a problem per se, but I think checking through which would be the best approach. Analogous example: mender/support/modules/rootfs-image at 0fb14b44e131ab7186bb86fe486332d420821de5 · mendersoftware/mender · GitHub
