Pi2 error on login

[johnvick]

Just done a fresh install on a Pi2 to test a new Pi cam.

Was working well on wired connection.

I setup a WiFi connection and that was working fine for a while and then I started to get this error on login using WinSCP and then PuTTY:

-bash: /DietPi/dietpi/login: cannot execute binary file: Exec format error.

This happens with wired and wireless connections.

Reflashed the SD and did and set it all up again - all working for a while and then same error ocurred.

Couldn't find a solution with Google - any ideas?

-bash: /DietPi/dietpi/login: cannot execute binary file: Exec format error.

Hi John,

This could indicate either a incorrect architecture for the bash binary (would be very strange), or, a corrupt filesystem.

Can you try running the following and paste results if it fails:

Code: Select all

 /bin/bash /DietPi/dietpi/dietpi-cpuinfo

Edit:
and please paste results of:

Code: Select all

echo -e "$PATH"

Hi Fourdee,

/bin/bash /DietPi/dietpi/dietpi-cpuinfo - gives:

/DietPi/dietpi/dietpi-cpuinfo: /DietPi/dietpi/dietpi-cpuinfo: cannot execute binary file

echo -e "$PATH" - gives:

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/binecho -e /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/binls

It's looking like the system is stuffed - I cannot run dietpi-software or the other utils on the home page.

I am wondering about an inadequate power supply - it was good enough for the Pi on its own but add a camera and wifi dongle maybe not so.

I'll get a better one today and try again.

Hi John,

Looks like the PATH is broken in /etc/profile. Please backup the current file

Code: Select all

/bin/mv /etc/profile /etc/profile.bak

Then select all, copy and paste the following code over SSH:

Code: Select all

/bin/cat << _EOF_ > /etc/profile
# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).

if [ "`id -u`" -eq 0 ]; then
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games"
fi
export PATH

if [ "\$PS1" ]; then
  if [ "\$BASH" ] && [ "\$BASH" != "/bin/sh" ]; then
    # The file bash.bashrc already sets the default PS1.
    # PS1='\h:\w\\$ '
    if [ -f /etc/bash.bashrc ]; then
      . /etc/bash.bashrc
    fi
  else
    if [ "`id -u`" -eq 0 ]; then
      PS1='# '
    else
      PS1='\$ '
    fi
  fi
fi

if [ -d /etc/profile.d ]; then
  for i in /etc/profile.d/*.sh; do
    if [ -r \$i ]; then
      . \$i
    fi
  done
  unset i
fi
_EOF_

Reboot the system and let me know if the issue still occurs.

[Fourdee]

Also, can you paste output of:

Code: Select all

/bin/cat /etc/bash.bashrc

Hi Fourdee,

Jumped the gun a bit and decided to reflash and start again - sorry if this has not helped your debugging exercise.

I've borrowed a better power supply from another device and so far so good - wifi and cam working.

And the shell login is back as it should be.

Thanks again for your help.

Hi John,

No worries, reinstall never fails . If it happens again, please let me know, would like to debug it

Hi Fourdee,

After a few days of trouble free use a similar problem has arisen and now when I login I get:

-bash: /DietPi/dietpi/login: No such file or directory

The dietpi folder is empty.

Any ideas? There is not much on the system so I plan to rebuild on a new SD card - I'll keep the existing one as is if you want to debug.

Hi John,

Very strange. It could be a filesystem corruption (PSU/SD issue).
Yes, worth trying a new card and stable PSU if possible. If you dont have one already, the official RPI PSU's are extremely good, I use them for all microUSB powered boards and i've never had an issue with them. Worth every penny for that peice of mind and stability.

Did you manually install/config any programs on the device? Or solely using dietpi-software?

[johnvick]

Hi Fourdee,

All I did was install PHPMyAdmin, MySQL - through your interface.

I suspect the SD card as dietpi has worked very reliably on a Pi 1 and XU4 here.

The PSU is an Apple 10W which I would have thought good enough for a Pi 2 with USB wifi and Pi Cam?
