I see where the confusion is, I have the nRF52832 and nRF52840 chips available, nRF52832 lacks the USB peripherals to support USB Mass Storage while nRF52840 does.

I believe nRF52833 is fairly new chip that also support USB natively and other cool concepts.

The USBD peripheral is the same on nRF52833 and nRF52840. It can support any USB class that nRF52840 will support. Our USB device library implements support for the following USB classes:

The usbd_msc example in the SDK does not provide a project for nRF52833 DK (PCA10100), but this is mainly because this chip does not support QSPI, which the example utilizes for one of the mass-storage disks.

I think the USBD interface will create a COM port and not a mass storage which I need. If that's true, nRF52840 is the next level.

Thanks,

In case you do not need the additional features of the nRF52840 (1MB Flash/256kB RAM, Cryptocell, QSPI), the nRF52833 also includes the USBD interface.

I am going to pretend I never ask that question. It makes total sense, I am looking at upgrade the chip to an nRF52840 to take advantage of the USB interface.

Thank you

Hi,

This firmware is running on the Interface MCU/J-Link On-Board debugger on the DK. Are you planning to include this chip on your custom board?

The nRF52832 does not have a USB interface, so there is no way to make it into a USB mass storage device on its own.

Best regards,
Jørgen
