Heap logging

Hi Michal,

I worked on SDK v6.0.18 and the ble_app_peripheral example.
I replaced the da14531.lib with da14531_with_heap_logging.lib on the sdk_arch folder as shown below:

Then I compiled and I attach the debugger to run the project:
Stop the program from running and type disp_heaplog() in the Keil Command window:

It works as expected on my side:

Hi,

as I mentioned I am using GCC not KEIL. I read in of the other thread in the communicty that I should be able to simply print heap values using arch_printf().

Best regards,
Michal

Hi Michal,

Thank you for the reply.
The CFG_LOG_HEAP_USAGE definition is designed to work with Keil IDE.
In order to do that with GCC you will have to implement your own disp_heaplog function.
The disp_heaplog function uses the following structs to print the Heap usage:

// Heap logging structs
struct mem_usage_log heap_usage_env     __SECTION_ZERO("retention_mem_area0");
struct mem_usage_log heap_usage_db      __SECTION_ZERO("retention_mem_area0");
struct mem_usage_log heap_usage_msg     __SECTION_ZERO("retention_mem_area0");
struct mem_usage_log heap_usage_nonRet  __SECTION_ZERO("retention_mem_area0");

Hi,

as I wrote, I defined this struct with "extern" keyword, assuming that they are defined elsewhere and that I will be able to use their content. However that is not a case, all struct's fields are always 0. Any idea?

Best regards,
Michal

Hi Michal, the heap logging works identically to Kiel with GCC.  You need to replace the :da14531.lib in properties->c/c++ general/Libraries tab (if using eclipse, if not then in your lib linking in your makefile) with the da14531_with_heap_logging.lib

Double check your configuration file, the CFG_LOG_HEAP_USAGE gets undefined later down in the file.

Then make your heap log variables as extern in the file you wish to print them. 

This should work from here.  You should see a warning from GCC about this this flag being set, for confirmation.

I am using GCC with these steps, and successfully printing them during run time:

Hi,

that is exactly what I did. However to print diferent params of heaps structs I was accessing them directly and then printing using `arch_printf()` eg `arch_printf("%d", heap_usage_env.max_used)`. Are you using different API ? I guess that should not matter? I will double check my configuration again.

Thanks,
Michal
