plz save me, Keil don't find my soft device...

ParkJS

Actually, I'm not good at using English. So I'll try to struggle to type this question...

Sorry, Last week. My boss gave me a Nordic Mouse to develop some embedded one.

Then I tried to join the mouse with My computer... I did install the program, called Keil.

and I used J-link from "segger ",,, then, i tried to control the mouse...

but I didn't understand the flash memory of the debugging option...

I did "Erase Sectors" nRF51xxx External Connection

Oh My Jesus,,, after that, the mouse did not work...

Next day, I tried to fight to recover it, but even In the debugging option, My Keil can't find SW device,,,

So, I searched that symptom in google, but they said tuning speed,,,

then I believe that, but It is still not working,,,

Plz save me

    It is possible that the softdevice was erased (normally it shouldn't be erased when uising "erase sectors").The softdevice will have to be programmed separately from the application. The softdevice comes with the mouse firmware (nRFReady Desktop 2 reference design).

    You can program the softdevice to the nRF51822 using nRFgo Studio. You can download the nRFgo studio from the nRF51822 webpage --> "downloads" tab --> "software" section. Remember to program the softdevice before programming the application.

    Update 02.03.16:

    This tutorial shows how to program the softdevice using the nRFgo Studio.

    For programming of the firmware, you can also do that through Keil. If you program the application through Keil, you can use debug mode and check where the code stops running. After trying this, could you let me know where in the code the problem is?

    nRFready Desktop 2 v.3.0.0 uses S110 v.8.0.0. In Keil "Project --> Options for target --> Target" make sure that ROM/RAM settings are set correctly. They should be the same as in the figure below:

    I got the mouse firmware, so I have installed nrfgo studio.

    then, I try to download the firmware to the mouse which it was erased from firmware.

    but, I don't know what i do.

    first when i click [Device Manager] - [Motherboards], it says Latest motherboard firmware : 7000 Boards connect : (Blank)

    second when i click [Device Manager] - [nRF5x Programming] I select "nrfready_desktop_2_v3.0.0/softdevice/s110_softdevice.hex" to program on tab [Program SoftDevice] then I select "nrfready_desktop_2_v3.0.0/precompiled_hex/desktop_mouse_release.hex to program on tab [Program Application] third I select "nrfready_desktop_2_v3.0.0/precompiled_hex/bootloader.hex" to program on tab [Program Bootloader]

    but it still not work,,,
