NXP usb secondary bootloader LPC51u68

[BetoGreen]

I am looking for example code for a secondary bootloader for 51u68. Anyone got there yet?

- I am using the the internal MSD for now but my customer wants a secondary bootloader.

- I tried AN12689,  the mcu-boot middlewhere does not show up in mxuxpresso when I modify the sdk as per AN12689 . I guess its for Keil...

I tried the Keil example. It is too difficult for me to convert to MCUxpresso and I don't want to spend weeks getting it going only to find its not what I wanted. They do things in a completely different way.

I have started to write my own.  Do you have any bootloader example code in MCUxpresso or LPCXpresso for any LPCxxx controllers you can share?

There is an application about USB Secondary bootloadr for LPC11u6x, you can refer to it : https://www.nxp.com/docs/en/application-note/AN12037_LPC11U6x.zip  

The demo can run under MCUXpresso IDE.

Hi BetoGreen 

There is no USB secondary bootloader demo code based on MCUXpresso IDE.

User needs to import Keil demo to MCUXpresso IDE by self.

Have a nice day,
