Laird BL620 - how to load softdevice?

[the_purple_pig]

I am trying to use the laird BL620 module not for the smartBasic, but to run my own firmware. I have just set it up, connected to my old segger JLink debugger. In Keil I connected to the device and erased it. Now I am trying to program in the softdevice, but in nrfGO Studio I cannot find anywhere to program SoftDevice.

The ability to program softdevice is normally under the 'evaluation boards' bit in the Device Manager, but of course that isn't there when I am connected to the BL620.

How can I do this?

It's really strange, if I program the ble_app_hrs that I know works on the PCA10001 eval board into the BL620 and set a breakpoint in the first lines of code in my main function, it never even makes it there. I thought maybe the Keil 'Erase Device' function perhaps left the softdevice in, but now I have no idea if the softdevice is there or how to put it back again.

OK, I'm certain the softdevice is there because if I compile the simple uart app to start at IROM 0x0, then erase fails when I try program, but it works when I start at 0x1D000.

But still, my debugger never makes it to the main finction when running code on the BL620, it is doing my head in.

Code is working fine now - it was the wrong version of softDevice in the BL620 compared with in my project.

I would still like to know how if I can program softdevices into custom boards using nrfGo Studio, or how it is best done. Thanks,

Try to use nrfjprog command tool

nrfjprog --programs <hex_file>
