How to program PCA10028 by drag and drop

[Andreas]

Hello,

I want to use the Segger drag and drop programming feature on the PCA10028. I have got a running application with the S120 softdevice. To use the mass storage drag and drop feature of the PCA10028, I merged my application .hex file and the sofdevice .hex file into one complete.hex file with the nordic mergehex.exe tool.

When I drop the new app.hex file to the mass storage device, It seems that nRF51422 chip gets reprogrammed, but the application doesn`t start execution.

Is there any thing wrong in my workflow?

Regards, BTprogrammer

What is the role of your application? if you program softdevice and application separately with nrfjprog does your application work? Are you able to debug your application, if yes, then find out where it fails.

1. erase your device -> nrfjprog -e

   2. flash softdevice -> nrfjprog --program S120_softdevice.hex

   3. read uicr -> nrfjprog --readuicr soft.uicr

   4. flash application -> nrfjprog --program application.hex

   5. read uicr -> nrfjprog --readuicr app.uicr

   6. both .uicr files should be same if your app is not writing anything to UICR
