FDS not working after SD initialize

[Maidu]

HI, I have nrf52832 and I am using latest SDK 14.2.0. 

I am using FDS and the problem is that before setting up BLE fds_record_write works fine but after setting up BLE all data using fds_record_write goes to dirty records. My ble part is just simple central what scanns advertisements and creates connectioin. Here is my main code.

ret_code_t ret;

ret = NRF_LOG_INIT(NULL);
APP_ERROR_CHECK(ret);

NRF_LOG_DEFAULT_BACKENDS_INIT();

ret = app_timer_init();
APP_ERROR_CHECK(ret);

NRF_LOG_INFO("RUN\r\n");

//INIT FLASH
fds_register(fds_evt_handler);

NRF_LOG_INFO("Initializing fds...");

ret = fds_init();
APP_ERROR_CHECK(ret);

wait_for_fds_ready();

fds_stat_t stat = {0};

ret = fds_stat(&stat);
APP_ERROR_CHECK(ret);

NRF_LOG_INFO("Found %d valid records.", stat.valid_records);
NRF_LOG_INFO("Found %d dirty records (ready to be garbage collected).", stat.dirty_records);

fds_gc();

//When I call here fds_record_write it works fine

ble_init();

//When I call here fds_record_write it goes to dirty records

Nordic guys, 

I discovered the exact same problem that Maidu is talking about.
With the 32k crystal all is working fine, but without it the FDS_EVT_INIT (or any other FDS handler event) is not trigger. Never.

That is a huge problem for me. Now I'm with 25 not working (custom) PCBs.
And I repeat. The previous version of that mainly same PCB, had a 32k crystal and there the (FDS) code is working without any problem.

Any solution for that? (SDK 14.2)

For both:

Have you tested this setup on an nRF52DK?

I just did a test with the same settings as described above on the DK, using the same example that I sent in a previous reply in this post, and it seems to work fine.

Is it the FDS that does not work when you try the PCBs without the Xtal, or is it the entire application (advertising etc.) that is not working?

 

BR,

Hi, it is only FDS what is not working. I run BLE in central role and works fine.

I did some debugging and looks like after setting up central then fds.c don't get in any fstorage events anymore fs_event_handler

Solved my problem followed this post

Just added nrf_sdh_soc.c to my project
