nRF51822 QFAA s110 to s130 softdevice upgrade using B.M probe?

[nar0909]

Hi Nordic and fellow developers, I have been working on upgrading the nRF51822 QFAA s110 and upgrading the softdevice to work as s130 for its (simultaneous Central/Peripheral/Broadcaster/Observer) advantages. The client wants the s130 for a project and wants to use them as a simultaneous master/slave mode. I used rogerclarkmelbourne and Nordic developers references and using the gcc-arm cmd the BMP discovers the target as ARM CORTEX M0. I tried mass_erase and target doesn't seem to accept it and tried cd c:/blah/blah/blah/nRF51_SDK_8.1.0_b6ed55f/components/softdevice/s130/ and then load s130_softdevice.hex and it was successful. But I get a warning under that for target "" missing stuff ?? and followed by the below 0x0001193e ??Capture-nordic.JPG Please refer the cmd snaps and help me through it.

But i have gone through [mem-location-nordic.JPG](/attachment/cf259e03049a8307994254e37a9265b3) mem location as s110 starts the flash from 0x18000 and s130 starts the flash from 0x1c000 but I have nothing in both locations?? So, please advice on what can be done to get this operating in master/slave mode like the s130. And I will be using an Arduino micro for the clients project (gas sensor project- master sensor in display panel and slaves responding their status when called by their UUID). I have a few hundred s110's but need atleast a dozen master s130's. Comments/ideas/gcc-cmd codes/ greatly appreciated. Thanks and Regards Nar P

Did you flash the application after erasing the chip and flashing the softdevice? What is the RAM and FLASH settings in the linker-file you use? Have you tried one of the s130 examples in the SDK?

hi joh2, well can u pls describe the process how to flash and flash settings?? I have tried using an example (ble_central_and_peripheral) but the I tried generating the makefile into .hex and merging the softdevice with makefile.hex and then loading that up into the nrf? Pls advice if this is the way/is there a simpler way? Thx nar0909

You can merge the application and softdevice hex-files using mergehex and flash it all at once, but since softdevice and application is separated in flash, you can also flash it separately. The following nrfjprog commands should work:

nrfjprog -f nrf51 -e
nrfjprog -f nrf51 --program /path/to/softdevice/softdevice.hex
nrfjprog -f nrf51 --program /path/to/application/application.hex
