nRFgo Studio and nRF52840 programming

[vard]

Hi Everyone,

I just purchased an nRF52840 PDK and I am trying to program it via nRFgo. I erased the flash, selected the latest s140_nrf52840_5.0.0-3.alpha_softdevice.hex and using the soft device tab I try to program it on the PDK. I get this "The flash is not erased" message which is strange because I just erased the flash and the flash erase operation was confirmed:

Any suggestions are greatly appreciated!

Thanks!

Hi vard!

Do you have the latest version of the nRF5x-Command-Line-Tools installed? If you don't, you should try updating and trying again.

If that doesn't work, try using nrfjprog to flash the softdevice to your board.

Let me know if none of the above helps, and we will try to find another solution for you.
Best regards,
Joakim.

Also, I cannot upgrade the JLINK firmware:

New firmware: J-Link OB-SAM3U128-V2-NordicSemi compiled Jul 24 2017 17:30:12 Current firmware: J-Link OB-SAM3U128-V2-NordicSemi compiled Feb 12 2016 12:15:53 Starting bootloader... Waiting for emulator to detach... OK after 182ms. Waiting for emulator to attach... Timeout. ERROR: Communication timeout. Emulator did not re-enumerate. ERROR: Firmware update failed.

Tried in boot mode too, it looks it is programming it, but it is not.

Thanks!
