Secure Bootloader for DFU support on nRF52805

[swanav]

I am developing a firmware for the nRF52805 SoC with a nRF52 DK. I want to implement the DFU support on the same. The secure bootloader example in examples\dfu\secure_bootloader for the pca10040e_s112_ble works properly and I am able to test out the DFU on the nRF52 DK. But I am not able to figure out what changes need to be done to make it to work on the nRF52805.

OS:

   Windows 10

SW Version: 

   nRF SDK Version: 17.0.2 (d674dde)

Hi Hung!

Changing these additional macros seems to have made it work. I can see the advertisement DfuTarg now!

#define NRF_SDH_CLOCK_LF_RC_CTIV 10

#define NRF_SDH_CLOCK_LF_RC_TEMP_CTIV 2

#define NRF_SDH_CLOCK_LF_ACCURACY 1

I will run some more tests and let you know if it worked!

Please also configure other LFCLK parameter. If you select NRF_SDH_CLOCK_LF_SRC  you need to configure other parameter, same as in your application (if the application run on your custom board)
Please try :

NRF_SDH_CLOCK_LF_RC_CTIV= 5

NRF_SDH_CLOCK_LF_RC_TEMP_CTIV = 0 

NRF_SDH_CLOCK_LF_ACCURACY = 1

Hi Hung!

It does work after these changes!

Thank you so much for all your help!
