nRFgo Studio does not see my nRF51-DK anymore

[Emil]

I run a laptop which previously ran this fine on Windows 7 x64. I now run Windows 10 x64. I cleaned out j-link, nrfgo studio, libusb etc and reinstalled nRFgo Studio again to be sure. The version is 1.20.0. www.nordicsemi.com/.../65589710

This is how it looks now:

Before this I ran nrfjprog as usual, but the parameters have changed on the new version 7.5.2 (I tried the version shipped with nrfgo studio installer later):

nrfjprog.exe --reset --program ARM/Debug/nrf51422_xxac_s110.hex

ERROR: Two arguments were provided that cannot be combined. Use --help to read ERROR: about the valid argument combinations.

I tried running it with --chiperase --program instead, but then the LEDs and everything went black. Did that pulverize everything on the chip?

If I do not supply it: "The area to write is not erased."

Also it seems to flash it fine because I get no errors, but the LEDs are completely off, indicating that the code hasn't executed, and as mentioned nRFgo Studio does not display it.

Did --chiperase take the softdevice too? "If --chiperase is given, all the available user flash (including UICR) will be erased before programming*"

I guess the same case is with 7.5.0 which I am using now with --clean ?

This is my final build output:

1>  C:/Program Files (x86)/Nordic Semiconductor/nrf5x/bin/nrfjprog.exe --clean --program ARM/Debug/nrf51422_xxac_s110.hex
1>  Parsing hex file.
1>  Erasing code and UICR flash areas.
1>  Applying system reset.
1>  Checking that the area to write is not protected.
1>  Reading flash area to program to guarantee it is erased.
1>  Programing device.

I guess this means that my softdevice is gone... How would I get it back if nrfgo doesn't work? I hope it is not bricked!

Is it dangerous to do this in that case?

I guess that won't make a difference as for detecting it in nRFgo

I can't help you with nRFgo Studio but if you think that nrfjprog works then try to megre Softdevice,App,Bootloader and ValidSettings in one file and program it. Here is full guide

[Emil]

Thanks! But I do not have a bootloader. Does the device manager show any libusb devices?

You images are not included, so it is hard to say what is wrong there.

nrfjprog.exe --reset --program ARM/Debug/nrf51422_xxac_s110.hex

ERROR: Two arguments were provided that cannot be combined. Use --help to read ERROR: about the valid argument combinations.

Please see this.

I tried running it with --chiperase --program instead, but then the LEDs and everything went black. Did that pulverize everything on the chip?

Do you mean --eraseall? This will erase everything.

Do this:

nrfjprog -f NRF51 -e
nrfjprog -f NRF51 --program softdevice.hex
nrfjprog -f NRF51 --program application.hex

Oh you had imgurl problems, right? The programming worked! I now have a working chip again. But nrfgo studio does not work.

I have a build action that used to program and reset. How is this done now? As mentioned I get the error

I attached the image devzone.nordicsemi.com/.../3d87f4c30494943c1017fadf518deec6

There are no libusb drivers present in device manager. How does nrfgo studio communicate with my device? Have you tested it in win10?

Also, I did test with nrfjprog --program and then separate --reset. But I still get an error "The area to write is not erased".

Great! nRFgo Studio is not tested on Windows 10. nRFgo uses nrfjprog. Could you try to install an older version of nRF Tools? Try 6.2.2, here. If you get that error I guess you need to erase first.
