      I have the same issue. I had a working RPi2 with Retropie 4.2 (all manually installed and updated). I decided to update Jessie to the actual build (via apt-get update / apt-get upgrade) und Retropie to the actual version 4.3.1.
      Now I get "illegal instruction" after trying to start Emulationstation.
      I tried to re-update Emulationstation but this didn't helped.
      What went wrong? Is my SD card corrupted? Any dependencies missing?

        @jimbo27 Did you also upgrade Jessie to Stretch ? I've seen this 'Illegal instruction' in ES when the wrong GLES libraries are installed and ES thinks it's running under X11 instead of the framebuffer.

          @mitu hm, I just made an update via apt-get update/upgrade and got a new kernel. I thought I'd stay on the Jessie path if I did a normal update. Did I accidentally installed Stretch over Jessie? How can I check this?

            My kernel is Linux 4.9.35-v7+

            cat /etc/os-release:
            PRETTY_NAME="Raspbian GNU/Linux 8 (jessie)"
            NAME="Raspbian GNU/Linux"
            VERSION_ID="8"
            VERSION="8 (jessie)"
            ID=raspbian
            ID_LIKE=debian

              @jimbo27 No, you didn't upgrade - as you mentioned below, to upgrade you need to change the distro release in the sources.list and then do a apt-get dist-upgrade. Just wanted to check that you didn't accidentally upgrade to Stretch, since it's still unsupported.

              Can you run EmulationStation via SSH (should work) and paste the complete error message ? What does ldd $(which emulationstation) show (paste here the output) ?

                @mitu said in "Illegal Instruction" on previously working RP:

                ldd $(which emulationstation)

                Starting Emulationstation via SSH results in:
                Illegal Instruction

                Using ldd $(which emulationstation) results in:
                not a dynamic executable

                  @jimbo27 Then it's not the same error as I've seen before. I'm at a loss.

                    @mitu Thanks anyway. I will restore my backup and install all updates step by step. Let's see at which point Emulationstation will break.

                      I made a fsck on the partition which contains Retropie. There were several errors. :(
                      So it seems my SD card is corrupted.

                        I can confirm it was the SD card. I bought a new one and made all updates. After that everything runs as intended. :)

                        PS: I buyed a more expensive SanDisk Extreme. Much faster than the SanDisk Ultra I had before!
