Can not enable USBD

[moon.kim]

Hi.

I am developing using nRF52820 with SDK 17.0.0 .
I test the USBD using the example code(\nRF5_SDK_17.0.0_9d13099\examples\peripheral\usbd_hid_generic), but the problem occurs in the part below.
nrfx_usbd_enable cannot be done.

 nrf_usbd_enable();
/* Waiting for peripheral to enable, this should take a few us */
while (0 == (NRF_USBD_EVENTCAUSE_READY_MASK & nrf_usbd_eventcause_get()))
{
    /* Empty loop */
}

HID is normally operated in Hex file included in SDK, but in dubug using IAR, a problem occurs in this part.

I use segger J-link.

Hi

Seeing as you're using SDK v17.0.0, I suggest trying out the project in SDK v17.0.2, as there were some issues with how some errata are applied in the 17.0.0 version that may cause the issues you are seeing.

Best regards,

Simon

Hi.

Thanks. It seems to have been corrected in SDK 17.0.2.

It works normally even when debugging.
