Hello,

I want to create an MCU bootloader application using USB CDC and IAP on LPC5514.
Please let me know if you have any helpful samples.

Best regards,
yamakatb

Hi yamakatb

The demo code USB CDC is for on board USB0 or USB1. not USB debug interface via  LPC432x.

So you can use SDK CDC demo for reference.

Thanks,

Jun Zhang

Here is an open source example that uses USB MSC as another reference:

Hi

I suggest you referring 

https://www.nxp.com/docs/en/application-note/AN12327.pdf

https://www.nxp.com/docs/en/application-note-software/AN12327SW.zip

There are USB CDC demo code under SDK folder. It's good to refer it as well.

 

Have a nice day,

Jun Zhang

Hello, @ZhangJennie 

Thank you for the information.
This SDK recognizes that VCOM is reproduced by bridging USART to USB CDC with LPC432x of U2 of the development board.
My configuration connects the LPC5514 port directly to the connector, would that be helpful in that case?

Best regards,
