Hi, I increased my WORKQUEUE stack size than It worked. Didrik Rokhaug

Thanks

The log shows that it is the system workqueue that runs out of stack. I assume you are sending the data from a work item?

You can increase the stack size of the system workqueue with CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE.

Hi,

Can you set CONFIG_THREAD_NAME=y and CONFIG_LOG=y and send me the log?

Best regards,

Didrik
