Retropie 4.0 - "Illegal Instruction" on Pi2, but OK on Pi3?

[BuZz]

nothing I know of has changed - the pre-made image works fine on rpi2/rpi3

Perhaps you can give me detail about the error - any other text shown ?

Do you have overclock settings in the config.txt that would be unsuitable for the rpi2 ?

@BuZz

Standard Config text, with the only change being the addition of "disable_audio_dither=1"

Just drops to terminal with the message.

[BuZz]

and what if you do on the rpi2 - sudo ~/RetroPie-Setup/retropie_packages.sh emulationstation install_bin and reboot ?

[BuZz]

oh you installed kids mode emulationstation ? That is a source install - and it will be built for the rpi3 target.

@BuZz

I'll try that and come back to you (In work at moment so will be later when i try it)

@BuZz said in Retropie 4.0 - "Illegal Instruction" on Pi2, but OK on Pi3?:

sudo ~/RetroPie-Setup/retropie_packages.sh emulationstation install_bin

Could it be kids mode that is messing with it as i presume that overwrites various parts of ES?

[BuZz]

No - I wrote what the problem is above. You installed the experimental "Kids Mode" emulationstation - which is compiled from source for the machine you were on - the RPI3 so it won't work on the RPI2. You will need to re-install it on the RPI2 (it will also work on the RPI3 then).

[Chillimonster]

@BuZz

BINGO!

That will be the issue then - so carrying out the instruction above will sort it?

[BuZz]

the instruction above will reinstall the standard emulationstation binaries.

if you want the kids mode es - you will have to re-install it from retropie-setup sudo ~/RetroPie-Setup/retropie_setup.sh

Excellent - Thanks for your help.

Makes perfect sense.

I'll re-install ES on the Pi2, then Re-install Kids Mode on the Pi2 and all should be good to go.

Thanks again.
