standard_init_linux.go:211: exec user process caused "exec format error"

[pro-sumer]

Nice project!

Hope I can get it to work on one of my Raspberry Pi's (currently tying wired on a 3B), but I don't see my Pi as an AirPlay receiver. Instead I see this error (repeating over and over again) on my Balena dashboard:

standard_init_linux.go:211: exec user process caused "exec format error"
Service exited 'rpiplay sha256:<redacted>'
Restarting service 'rpiplay sha256:<redacted>'

I can't access the rpiplay terminal (also repeating over and over again, except for the first line):

Connecting to <redacted>...
Spawning shell...
Error response from daemon: Container <redacted> is restarting, wait until the container is running
Error response from daemon: Container <redacted> is restarting, wait until the container is running
SSH session disconnected
SSH reconnecting...

What can be wrong here? How to fix it?

(Note: I'm completely new to balenaCloud; apologies upfront if I make a rookie mistake)

Hello,

Thanks for trying the project!

Can you please share more details on how you deployed the app? The err looks like an architecture incompatibility.

• Which device-type are you using for your fleet?
• Are you using Raspberry Pi 3 32-bit or 64-bit OS image?

[pro-sumer]

Initially I tried joining the balenaHub openFleet without creating an account. That got me to seeing an AirPlay receiver on all of my Apple devices, but none could connect to it. Since I did not know whether I could check any logs, and wanted to learn more about balenaCloud anyway, I decided to try the second suggested path as well. I created an account, installed balenaOS 2.83.21+rev1 (without even noticing that there are 32-bits and 64-bits versions) and used your "1 click" button. Since this attempt did not result in seeing an AirPlay receiver on any device, I looked at the logs, which are the ones I posted in this issue.

• My dashboard displays my Pi as "Raspberry Pi 3"
• I have no idea which OS image I installed and I can't see it on my dashboard either...

[pro-sumer]

Looks like the default balenaOS is 32-bits.

Should I try the alternative 64-bits version?

(Which one does RPiPlay need?)

[tecandrew]

yup, seeing this issue too. running on pi zero w. some exec prob isn't compatible

I was able to reproduce it. Looking into it. Thanks for reporting

[rahul-thakoor]

hey @tecandrew @pro-sumer I added a fix. Can you please deploy the app with the latest changes?
Cheers

[tecandrew]

looks like the service executes now (no error message) and I can see it on my network. doesn't mirror anything, but might be because i'm running development OS or the pi zero can't keep up

[rahul-thakoor]

Hi @tecandrew you have to use screen mirroring from the control center. Casting music only is not supported. If you want to only play music please consider balenaSound.
