Flash Issue

[Nagma]

Hi Nordic Team,

My dev environment is as follow:

nRF52832(ble central)+ S132+ SES

We are using BLE Chip on a custom board.

When we flash hex file ( softdevice hex file and application hex file) through nRF connect Desktop App, we are unable to establish ble communication.

But when we flash the code through Segger Embedded studio , we are able to establish communication. However when we turn off the power supply and turn on again, code is not booting from flash.

Kindly help me resolve this issue . Thank you.

Hi there,

Do you have onboard LFXO crystal? If not, have you configured the board to use the RC oscillator instead?

We are using onboard oscillator. 

Also, we are using elf file through the ide, if we use hex file it doesn't work

So it works if you build the project in your IDE and then flash the IC, but it doesn't work with the pre-compiled hex? Could try to use nRF Command line Tools and flash the ble_app_blinky_pca10040_s132 hex located at: Your_SDK\examples\ble_peripheral\ble_app_blinky\hex:

nrfjprog --program ble_app_blinky_pca10040_s132.hex

All the precompiled hex files available in hex folder are working completely fine but when we are building our integrated ble central project in segger ide the hex file generating in the output folder is not working at all.

And this is a modified example? How are you trying to flash your hex file, via nRF Command Line tools?  

[Nagma]

Yes our project basically is the integrated project consisting of ble uart multilink central example project with our own custom services + nfc writable ndef msg project+ spis. 

We are flashing hex file generated after building our project through nrf connect desktop tool.

Hi, 
Have you also remembered to flash the Softdevice hex?
