Hi,
I followed the instructions for importing the Thing:52 firmware into SES and managed to get the firmware compiled and loading, and the code reaches the main function without any apparent problem. When it gets to the application though I get an error in m_ble_flash_init. The problem is in the structure returned by FS_SECTION_ITEM_GET(i) within fs_init (called within m_ble_init->m_ble_flash_init->fsd_init) - particularly in these lines (fstorage.c:363) : -
p_config_i = FS_SECTION_ITEM_GET(max_index);
p_config_i->p_end_addr = p_current_end;
p_config_i->p_start_addr = p_current_end - (p_config_i->num_pages * FS_PAGE_SIZE_WORDS);
The write of p_current_end to p_config_i>p_end_addr doesn't happen and the value remains 0. The same is true for p_config_i->p_start_addr.
p_current_end is 0x00080000, i.e. the end of the flash section - as expected. The p_config pointer is pointing to 0x5beac.
Of course what then happens is that p_current_end gets update to 0x0: -
p_current_end = p_config_i->p_start_addr;
This causes problems later on.
There are earlier warnings which Iooked into. The first on happens because all the structure values are 0, so the drv_ext_light_off driver tries to setup a timer with timeout_ticks = 0, so this generated an NRF_ERROR_INVALID_PARAM error.
It seems these errors could all be down to the same root cause - the inability to write to these structures.
Any idea what I am doing wrong?
Thanks in advance for any help.
Phil.
p.s. If it is useful - here is the trace from the debug console.
