peer manager init returns fatal error

[Sascha Schmidt]

Hi,

I've tried to implement the DFU_buttonless example to my development board. I programmed the bootloader and the settings-page. The bootloader detects the application and starts it, but then when peer manager is initialized, it returns a fatal error.

Does anybody know this problem or have a hint where my problem is?

Thanks in advance!!!

I'm using SDK15 SD 6 and the gcc compiler (if that helps)

Kind regards

Hi Sascha,

Please check if the bootloader start address is correctly stored at address 0x10001014 (is in UICR section). The Peer manager's flash data will overlap with the bootloader code if the UICR register is not set. You may use nrfjprog to read out the register: nrfjprog --memrd 0x10001014

Kind regards,

Vidar

Hi Vidar,

I checked that and the start address is correctly stored

Thanks for confirming. I can't think of any other obvious reasons for this error, but would helpful to know what the error code is, and from what function call it was returned.You can get this information from the debug log if you have compiled your project with the 'DEBUG' flag added to your list of pre-processor definitions.

I have not managed to reproduce this error here. I used the bootloader and buttonless template example with GCC.

Hi, thanks for your help in advance. I've checked the error code. The function pm_init returns error code 3 (INTERNAL_ERROR). I checked inside pm_init which function returns an error code and found out that pds_init() returns error code 134. Inside pds_init() the function fds_init() returns error code 11 (NRF_ERROR_INVALID_DATA or NRF_ERROR_STORAGE_FULL). Could it be thatI haven't enough flash assigned to the softdevice?

Ok, that confirms that there is not enough flash for FDS. FDS will attempt to allocate 3 flash pages below the bootloader by default (number of pages is configurable, see FDS_VIRTUAL_PAGES in sdk_config.h). 

Please check if the application code is possibly overlapping with the application data section (memory layout).
