Hi. That sounds like a good fix.

Hi. I found a solution. I suppress initial reset and halt command in startup page of debug configuration (I use Eclipse). If you think is a good fix, you can close the question. Thanks a lot.

Strange. Can you try to do a HW reset of your board?

Hi, I try to powering my board without D+ and D- signal and, of course, I can't enabled USBD. But there is infinite loop too. I try to powering NRF only with VDD (no VBUS), I disable USB power detection, and I have the same result. Perhaps USBD can't be enabled without VBUS. I use SDK 14.2.

How are you powering your board? Can you try to power it by a sepparate supply (not by USB)? Our developers recommend doing this while developing.

If this isn't working, what SDK version are you using?

Hi, Yes it is the same code.

Are you using the exact same code on your PCA10056 and your custom board? If not, have you tried?

Hi,

On my Own board, I use SWD port with J-Link Jtag Ultra.

What do you mean by JTAG? The PCA10056 supports SWD, but not JTAG.
