Z Spin Lock with Threading

cchoi22915

Hi All,

I am able to send data by creating a thread in the nRF. The reason for this is every once in a while the send() command hangs and trips the watchdog.

I have a separate timer that triggers the thread to abort, but when I attempt to create a new thread, I get the following:
.ASSERTION FAIL [z_spin_lock_valid(l)] @ WEST_TOPDIR/zephyr/include/spinlock.h:129

I believe this to happen as it is a blocking send and a spin lock is applied and valid. Is there a way to remove the spinlock before aborting the thread or to reset this behavior and create a new thread to send data?

Thanks,
Chris

In other words, is there a “cleanup” function before killing a thread?
