Enabling A-GPS with SUPL causes boot panic

[Samuel Pell]

Hi,

Turning on A-GPS (using the SUPL library) causes our application to encounter a boot panic ("unable to find bootable image"). Similarly, running the nRF9160 GPS example with SUPL both enabled and disabled causes a boot panic. Running the A-GPS example with SUPL enable does not cause a boot panic.  Any thoughts as to what could be causing these boot panics? What are your recommended next steps?

Thanks,

Sam

Hello Samuel,

Any thoughts as to what could be causing these boot panics? What are your recommended next steps?

which NCS and SUPL library version are you using? Are you running the application on a custom board or the nRF9160 DK?

Regards,

Markus

Hi Markus,

We are using the Thingy:91 with NCS v1.7.0 and SUPL v0.7.1.

Thanks,

Sam

Thanks for the feedback, Samuel!

How are you flashing the e.g. nRF9160: GPS with SUPL client library sample to your Thingy:91? Are you using USB or an external debug probe?

We are using an external debug probe and are programming it using the Segger environment.

Thanks,

Can you share the ../<build folder>/zephyr/.config file from the GPS sample build that doesn’t boot?

Thanks,

Markus
