PCA10059 USB nRF52840 Dongle Direct Mode Test Inquiry

[ywmw]

I am all new to nRF52480 dongle, would like to use Direct mode test getting error message in Direct Test Mode software (v2.0.3).

Can not communicate with device. Make sure it is not in use by another application and that it has a Direct Test Mode compatible firmware.

During testing, only run Direct mode test software. Dongle information as below:

PCA10059

2.1.1

Please kindly help to advise where I could get direct test mode firmware or other fixes can resolve this issue.

Thanks a lot!!

Hello,

Could you please download the nrf commmand line tool and run "nrfjprog --recover" before programming? The error you are seeing  might be because of the access port protection enabled in nRF boards. After running the command, you try programming the dongle again.

Kind Regards,

Dear Abhijith,

Having tried to use j-link debugger and "nrfjprog --recover" command to recover the dongle and got "[SeggerBackend] - JLinkARM.dll reported "-1", "An unknown error." message.  (see attached log)

6320.log.log

Besides, we found the following Direct test mode example files in SDK 17.1.  Please help to advise which one may compatible with PCA10059 nrF52840 dongle?  If not, is there available BIN for PCA10059 for Direct test mode.

Thanks in advance for your kind help.
