CONFIG_HEAP_MEM_POOL_SIZE and k_malloc, k_free not working in nrf51_pca10028

[stephenmasih]

Describe the bug
I my application i am using the board nrf51_pca10028. I the prj.conf file I am defining a CONFIG_HEAP_MEM_POOL_SIZE=1024 for involving a k_malloc() and k_free(). Even when I define a thread in the kernel it doesn't seem to show any output. When I replace the entire thread code in the main thread it works fine in nrf52, not in nrf51. The code works fine with board nrf52_pca10040. But it shows no output in the console with nrf51.

To Reproduce
Steps to reproduce the behavior:

1. west build -b nrf51_pca10028 --pristine
2. west flash

Expected behaviour
There should be dynamic allocation of memory for my linked list in the Bluetooth application.
t_ble_scan() is a thread function and main() thread is also defined.

@joerchan could you try to reproduce this?

I tried debugging, any code defined inside a thread. The code gets compiled i am able to get the zephy.hex file. But the code does not work at all. The same code I tried with nrf52, everything seems to be okay. As you can see above in the screenshot t_ble_scan() doesnot work in nrf51 but it does in nrf52 boards. Please help.

@stephenmasih I have no way to reproduce this issue. Please update with a description on how I can reproduce it. I cannot really do anything with a screenshot.

You are not checking the returned value of k_malloc, you probably should check that it is infact non-zero before using it.

@stephenmasih I am closing this issue since there has been no activity on it for a while. Please reopen with guidance on how to reproduce if this is still a problem.
