nrf_fstorage_init() gives hard fault

I compared your flash_placements.xml file with the one in the fstorage example in the SDK. By removing the line you have under FLASH:

<ProgramSection alignment="4" load="Yes" name=".fs_data" />

And replacing it with the line from the example, below ".nrf_sections":

<ProgramSection alignment="4" keep="Yes" load="Yes" name=".fs_data"  inputsections="*(.fs_data*)" runin=".fs_data_run"/>

I no longer get the hardfault. I do however get errors from the first call to nrf_fstorage_write, but this is caused by the address to be outside the fstorage address area that you defined in your application.

Best regards,
Jørgen

Jørgen, here is the file, thank you very much! I worked on it inside examples/proprietary_rf folder.

I removed everything non related to fstorage from project and observed the same behavior.

Hard fault happens inside nrf_fstorage_init() at last line inside: return (p_fs->p_api)->init(p_fs, p_param);

Hi,

I cannot see any obvious mistakes in your code. Could you debug a bit more to determine exactly which function call in nrf_fstorage_init function that generates the hardfault?

Could you also post the full project for us to reproduce and debug this?

Best regards,
Jørgen
