USB and BLE - IRQ Enable

Andrew

I am trying to use both USB and BLE on an NRF52840 using SDK 15.  It hit a hard fault during initialization, specifically when it tries to enable the USBD IRQ.

It looks like it is happening on line 1850 uf nrf_drv_usbd.c:  NRFX_IRQ_ENABLE(USBD_IRQn);

Does anyone know what might be going wrong?

    I had the wrong system config files included.  I had the generic ses_nrf52_Vectors.s and system_nrf52.c files.  Now I am using the ses_nrf52840_Vectors.s and system_nrf52840.c files.

    It had been looking liked it worked because I hadn't been using any NRF52840 specific features yet.  Then when I added USB it finally didn't have enough information to make things work.  But now with the the right files in place the interrupts can get enabled correctly.
