Missing Softdevice call to nrf_fstorage_sys_evt_handler

Hi,

I didn't do the test but I found the reason.

Inspired by this: https://devzone.nordicsemi.com/f/nordic-q-a/29137/fds-not-able-to-write-in-sdk-14

I add this to <sdk_path>/components/softdevice/common/nrf_sdh_soc.c:

void
workaround_init() {}

And call that function from my code where I initialize the memory.
That solve my problem,

More in general the problem is in final elf file (the one that I convert to IHEX and than flash on device are missing all objects (variable/struct/function) from the file above. I check that using:

arm-none-eabi-nm main.elf | grep sdh_soc

Going further I found they are present in an intermediate file nrf52832.a but where removed when linked with the rest of my code.

While the workaround I report above above force last step of compiler/linker to include them.

I'll going to investigate if there is an option or a parameter to put in Makefile that force the copy of those object.

Any suggestion still welcome 🙂

BR,
Davide

Run through the test description of the example, and make sure that you get it to work.

The test description is found on:

Thanks for the advice. I'll try.

Can You recommend to me good way to use the debugger to find the problem?

I mean something to watch or where to put a breakpoint or similar?

We are really short on staffing this month due to summer holidays in Norway, so I can't familiarize myself with your setup.

[quote user=""]We use gcc as compiler and, what make found the problem difficult, we use Contiki. That means we don't have a simple c application but it is spread in different C and makefile divided for platform/cpu, modules and applications.[/quote]

I suggest you start by checking out the SDK example SDK\examples\peripheral\flash_fstorage\pca10040\s132\<any IDE>\

to see how the callbacks work with the softdevice. When you are familiar with it, you can start implementing that to your Contiki project.

I also suggest using an IDE for debugging. You can use Segger Embedded Studio(SES). It is free. Nordic has fixed full licenses for customers developing on Nordic products. Please see:
