nRF52 PCA10040 Bossa Program Port

[Sugitani]

Sorry for being funny English because I am using translation software.

Hello, I am using PCA 10040.Version is V1.1.0. I am in trouble because it is recognized as "Bossa Program Port" when I connect it with PC.

For reference, the environment construction procedure is as follows.

1. Install Keil
2. Download Software Development Kit(nRF5-SDK-zip Version 14.0.0)
3. Install nRFgo Studio-Win64 with full installation(Version 1.21.2)
4. Open blinky in SDK and initial setting

However, J-Link does not seem to recognize it as shown in the figure below.

At this time, it appears in the device manager as shown below.

Originally "JLink CDC UART Port" should be displayed.

"nRFgo Studio" will also be disconnected.

The correspondence we tried is below.

1. Replace J-Link with the latest version 6.20a.
2. Hold down the "BOOT / RESET" button on the PCA 10040 and turn on the power. Nothing happened.
3. I tried connecting "PCA 10040" purchased at the same time. It was recognized normally without any problem.

Is there a solution?

Thank you for reading it until the very end.

You should also see a "JLink Driver" under the "Universal Serial Bus Controllers" in the device manager, and also a (D:) or (E:) drive in the windows explorer. Which windows OS are you using?

Hi,

We see this issue from time to time, but we haven't figured out why it happens yet. If you open a support case in MyPage we can help you out though. Please refer to this devzone thread in MyPage.

Best regards

Thanks for your comment. My development environment is windows 10 Pro 64bit. The device does not appear in windows explorer. I want to solve this problem. However, I do not want to spend too much time. In parallel, we will proceed with another "PCA10040" which works without problems.
