nRF52840 Overlapping .hex data & Soft Device match error

[Chiprobot]

I am new to the Segger Studio and nRF52840 . (However not a Newbie to Microprocessors)

Off the Bat :- Blinky example works fine...

.....however when I try to get the PWM_driver example I get these errors below in picture.

The example is for "pca10056" which is why I followed the dongle guide below, adjusting predecessor to the nRF52840 and memory macros.

 https://devzone.nordicsemi.com/nordic/short-range-guides/b/getting-started/posts/nrf52840-dongle-programming-tutorial

however when I port across the program .hex file and the Soft Device .hex file ( S140) there is a memory clash. I have also tried S132 (also errors).

If I place just the program .hex and write to device a window pops up asking for a soft device selection !!! It does not matter which I choose (I went through all).

My Questions are :-

1. Is there a specific soft Device for the nRF52840 ... (I could only find the recommended s140_nrf52_7.2.0_softdevice.hex ) ?
2. How Can I tell which Soft Device is needed (i.e. from the examples). ?
3. Can the Soft Device be Merged into code somehow in the Segger Studio ?

Any pointers would be greatly appreciated.

The confusing part for me is that other Project Example's (not all though) are contained with-in a folder "named" with the actual Software device required, the pwm-driver example i want to run just gives a folder marked "blank" ! no indication of SD required.

Yes, which means that the example doesn't include a softdevice. All of the "blank" examples are under the peripheral folder which doesn't include any softdevice. The softdevice examples are found under the ble_central, ble_peripheral or ble_central_peripheral folder. 

The peripheral only examples are meant to showcase how to use the peripherals on the nRF without implementing the Softdevice.

Thats what I was led to believe (no Softdevice required), however when I Port over just the program .hex ---- its still asking me for which Softdevice is installed !   (need user input popup)

[Chiprobot]

Which means the upload cancels.... (its still asking for Softdevice even though as you say one is not necessary)

Hi,

I think I've misunderstood your intention. I thought that you wanted to merge the SD and the PWM example together. But you're saying that the programmer app is asking you to flash a softdevice even when the pwm example doesn't use one?

however when I port across the program .hex file and the Soft Device .hex file ( S140) there is a memory clash. I have also tried S132 (also errors).

 This sentence got me confused.

Thanks for your input's BTW .. it has deepened my understanding of the nRF's playing field .

Yes indeed the same goes for the temperature example... although it should not need a SoftDevice... this also ask's you with a "PopUp" which SoftDevice you are using!!! . i.e. thats using the nRF Connect to port just the program file across.

I am using the "latest" SEGGER Embedded Studio for ARM
Release 5.20a  Build 2020110401.44169 and latest SoftDevices (to date S140 and S132)

I have had success with the BLE heart rate monitor (talking to my Garmin bike computer) ... as that uses the S140 Soft device, so I am currently checking that against the PWM and the Temparture project... there must be a difference I can ferret out.
