Unable to connect to the nRF52811 via nRF Connect Programmer

[mdehrnsb]

I have a custom PCB that I designed for use with the nRF52811.  I have tried to connect to it using the nRF Connect Programmer to program a Soft Device but I am unable to connect to it successfully.  When I start the Programmer app, the Programmer is able to connect and identify the chip but hangs when trying to read beyond the ID.  See below:

The initial connection operation hangs and the selection buttons such as Read and Erase never become active.  I have built two identical boards with nRF52811 with the same results.  As a comparison, I built a third board but used a nRF52832 instead and the Programmer app connects and complete the initial connection.  I am able to program a soft device, erase, etc. I am using a nRF52840 DK as the debugger.  I have tried to update the J-Link firmware but the January 2019 firmware appears to be the latest that I can find.

Any help would be appreciated.

Hi Mark

What version of nRFConnect and the Programmer app are you using, and what J-Link firmware version is the latest one you found?

Please generate a system report (see picture below) when you try connecting your nRF52811 to nRFConnect and upload it here, so I can have a look.

You could also try using the nRF Command Line Tools to program your device to see if you have any luck with that.

Best regards,

Simon

Simon,

I am using the device on a Mac but I will try it on a PC . I have attached the log file as requested.nrfconnect-system-report-2019-08-20T01-48-12.394Z.pdf

I was able to connect it the target using J-link Flash Lite and program the soft device.  I will try on another PC to see if the results are the same.

Thank you.
