3. DFU Bootmode does not work with E1 version board - Any thoughts
Thank you,

3. DFU Bootmode does not work with E1 version board - Any thoughts?
The E1 board USB0 doesn't support USB device mode because of the on-board usb hub...
Please refer below in the EVM user guide: 3 Known Issues and Modifications section
3.3 Issue 3 - USB Boot descoped on E1
Applicable EVM Revisions: E1
Issue Description: Due to the USB0 port being routed through a Hub IC to the Type-A connector, USB boot cannot be supported on E1 boards.
Fix: E2 boards and newer use USB1 to the type-A connector and have moved the USB0 controller used for boot to the second USB Type-C port so that both DFU and MSC boot can be supported. The USB hub IC has also been dropped to simplify board layout and BOM.
