This should be easy to fix. However, the fix might require rebuild of the driver? @ARMmbed/team-ublox Please advise.

I can see at least two functions, having default switch statement assert and no return.

This would be good to have in 5.13.0-rc2 - fix asap.

@0xc0170 we are working on ARMC6 support for driver but that is currently leading to hard-fault

we require support from u there is currently no label to mbed export -i eclipse_armc6
secondly i will need support regarding how u setup openocd debug agent in eclipse after mbed export - eclipse_armc5 using stlink?

Awesome, so should also fix this error about no return value.

In the meantime, use uvision6 for debugging with armcc6. Or make armc6 and add this to your eclipse project.

I havent used openocd for a while, pyOCD should work out of the box without any config.

Note, to have this fix in rc2, it should be sent for review latest tomorrow

Note that warning seen in the description should be solved by #10740

@aqib-ublox Is there any update for this issue?

[MarceloSalazar]

I confirm this is still an issue on Mbed OS 5.13.2
@aqib-ublox can you please investigate?

@0xc0170 @MarceloSalazar https://github.com/ARMmbed/mbed-os/pull/11370 generated please verify?

Tested locally, test compilation for ARM with release profile OK. I'll close this issue as resolved
