nRF9160 Dynamic Threads

[AMG]

Hi,

I trying to integrate a thread inside a function to run in parallel with the main program.

I have tried the THEAD_DEFINE function and it works but it is static and has to run at the start of the program run time.

K_THREAD_DEFINE(thread1,STACKSIZE,funcation call,NULL,NULL,NULL,PRIORITY,0,0);

I am also trying with thread_create but when I flash the dk it goes in a dump and keep looping. I am not sure what is the problem there.

//k_thread_create(&my_thread_data, my_stack_area, K_THREAD_STACK_SIZEOF(STACKSIZE), funcation call, NULL, NULL, NULL, PRIORITY, 0, K_NO_WAIT);

Is there another thread call function that will run inside a function.

Hi,

Have you followed the documentation on how to set up the stack area and thread?

Best regards,

Hi Didrik,

Yes, followed the documentation and got a dump as I mentioned. If I try to run a gps thread this is how I have it.

#define STACKSIZE 4096
#define PRIORITY 7



K_THREAD_STACK_DEFINE(my_stack_area, STACKSIZE);
struct k_thread my_thread_data;
extern int gps(void *, void *, void *);

k_thread_create(&my_thread_data, my_stack_area, K_THREAD_STACK_SIZEOF(STACKSIZE), gps, NULL, NULL, NULL, PRIORITY, 0, K_NO_WAIT);

You should have K_THREAD_STACK_SIZEOF(my_stack_area), not STACKSIZE.

If that doesn't help, could you try to enable logging (CONFIG_LOG=y), or use a debugger to try to see what is actually causing the crash?

When enabling logging, you might also need to set CONFIG_RESET_ON_FATAL_ERROR=n and/or CONFIG_LOG_IMMEDIATE=y.

Hi Didrik,

I don't know how I missed that thanks for the help.
