Device Firmware Upgrade (DFU) over USB on LPC54114

Haider_Ali — Tue, 19 Mar 2024 19:04:27 GMT

Hello, I'm new to NXP controllers and need help in knowing if LPC54114 supports upgrade of flash via USB using DFU class?

In the datasheet, for ISP modes only USB mass storage device class (MSC) is mentioned.

Where as in USB section it says that it support DFU.

Appreciate if can share any example or where to get further information on above.

Is there any utility or software which can be used to upgrade the firmware?

thank you

Hello @Haider_Ali

1)Table 2 ISP mode means:

If use ISP mode to update firmware, supports USB mass storage device class ( MSC) mode. Not supports USB DFU.

2) 34.2 &34.3 (in your screenshot ) means:

USB driver in iLPC54114 ROM can implements DFU. If you want to use DFU update firmware, can write application based on the USB driver. For ISP mode update firmware, no need add application code.

Thank you.

Regarding DFU update firmware, is there any example code or library to implement it?
