USB does not enumerate after moving to SDK 15.2

[Boaz]

I'm building a project on top of cli examples:

• <SDK>\examples\peripheral\cli
• <SDK>\examples\ble_central_and_peripheral\experimental\ble_app_interactive

My goal is do an interactive CLI session over USB, including BLE commands from the second example. I'm using nRF52840-PreviewDK

While CLI over USB for SDK15.0 (nRF5_SDK_15.0.0_a53641a), the same example does not work for me in SDK 15.2 (nRF5_SDK_15.2.0_9412b96). I assume this has to do with USB errata (e.g. here).

Anything I can do other than using an nRF52840-DK instead?

Device information: 52840_eng_a ((0x10000130UL == 0x8UL) and (0x10000134UL == 0)).

Hi,

 

From SDK 15, the support for engineering A devices were dropped. I would strongly recommend that you develop on a nRF52840-DK, as this is the production silicon.

Kind regards,
