[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

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,,,
