LPC11Ux DFU capabilites

gionaimperatori — Fri, 02 Dec 2016 16:01:29 GMT

Hi,

where can I find information about the LPC11Ux DFU capabilities?

And about DFU in general?

The information about DFU on this site are poor.

The LPC Scrypt would work with such a device as well?

Thank you in advance.

Hi Giona Imperatori,

The attachment illustrate the image creator tool and DFU utility programs to help facilitate the use of a DFU SBL with an LPC11U3x/2x application to enable firmware updates in the field.

The LPC Scrypt doesn't support to work with the LPC11Uxx, as the LPC11Uxx can't boot from the USB which the DFU class is used to download a boot image.
Have a great day,

Hi Ping,

again thanks.

I'm still a bit confused.

The AN uses the image creator tool to use the DFU on LPC11U3x/2x.

As far as I understood, this tools has a pre-compiled SBL which allows to download an image via DFU drivers.

Does this tools support only LPC11U3x/2x ? What about LPC11U6x ?

Regards

Hi Giona Imperatori,

The application is suit for the LPC11U68, the biggest difference between the LPC11U68 and LPC11U2x/3x is the kind of Cortex core, the LPC11U68 use the Cortex-M0+ versus the LPC11U2x/3x use the Cortex-M0.
Have a great day,
