Reset when the log () function is executed;

agarcia — Thu, 06 Jan 2022 18:37:57 GMT

I am working with the MC9S08PT16VWJ microcontroller when I execute the following instruction:

b = (float) log ((double) c);

A reset occurs on my card when the value of c is greater than 150, I have wachDog disabled.

What I can do?

Can you please check the SYS_SRS register

I am thinking that you are running out of memory

Have a good day

Floating point support requires more stack space. Try increasing STACKSIZE in PRM file.
