Part Number: CC2640R2F

Hi.

I use CC2640R2F LaunchPad

CCS-C Compiler Version : TI v16.9.3.LTS

I use Task_sleep.

LED and UART Message in Thread, it always work!! but BLE is not work.

first :

I create user_task and stack size 512 -> it working BLE with android phone.

just increase stack size 1024 -> it not working BLE with android phone.

second :

I made global value char array [1024] for OLED display -> it not working BLE with android phone.

third :

some code size increase -> it not working BLE with android phone.

I think code size & ram size was no problem.

Hi Jjang,

It's possible you're running out of ICall Heap. Profile the ICall Heap usage with : software-dl.ti.com/.../gen-debugging.html

You can try using Cache as RAM to get perhaps get more ICall Heap space.

Thank you.

Do you have any idea how to check heap memory usage in ccs-c ??

ccs-c I'm not sure if I want to check the heap memory usage in the map file.

Could you tell me if heap has information on where you can check the overloaded information?

So that can check the heap memory usage and make sure do not overflow.

Hi Jang,

The instructions I posted earlier work for all versions of IDE, CCS and IAR.

When HEAP_METRICS are enabled, they allow you to see when a HEAP allocation fails - which I believe may be what your issue is.

Give it a shot, let me know if you run into problems!

Rebel
