k_msgq_put returning EDEADLK

[ibiglari]

Hi,

I am modifying the code to asset_tracker_v2 on Thingy91 to send data to my own server instead of Azure / AWS / Nordic Cloud. I am getting error code -35 (EDEADLK) when k_msgq_put() is called in modules_common.c in module_enqueue_msg(), but a quick look at Zephyr documentation shows that k_msgq_put() only returns ENOMSG or EAGAIN, so I am a little lost. Has anyone come across EDEADLK being returned by k_msgq_put()?

I'm using SDK v1.6.1 at the moment, trying to download v1.7.1 to see if I'll be facing the same issue there.

Cheers,
Iman

Hi,

 

If you are using newlib c, the errno is different. -35 is ENOMSG:

Kind regards,
