Heap overlaps absolute placed section stack issue

[Kashinath]

Hi all,

I am Using SDK15, chipset is nrf52810 , In ble_app_uart application  i have added the BLE_NUS_C and TWI application code , before this i have added only TWI to ble_app_uart application then its working fine, but later when i combined the ble_nus_c to the same application,  then i am getting following error:

Error message :section .heap overlaps absolute placed section .stack  

can anyone suggest me for this, 

Thanks in advance

Hi,

What IDE/Toolchain are you using ?

What are __HEAP_SIZE and __STACK_SIZE set to in your project?

Could you try to reduce the heap size?

Hi Sigurd,

I'm having this same issue. I tried reducing my heap size from 1024 to 1000 bytes. This worked temporarily, but when I started writing more code, the same error in the authors post occurs. Is there a better solution than just continuously reducing the heap size? 

Thanks.

Hi scla,

There is no heap required by nRF52 SoftDevices, so if you are not using dynamic memory allocation (malloc/free) in your application you can set the heap size to 0. Depending on how much RAM your application uses, you could maybe try to increase the stack size also.
