LPC1549 USBSerial is not working

I tried to use USB serial with LPC1759 but it did not work. Using the interface MCU on the LPC expresso board is not the case. I am trying to use target MCU's ( lpc 1549 ) USB as a serial gate but I couldn't make it work. Please let me know if you guys have any idea about how to make it work.

Hi,

Did you use sample code of the USBSerial?

https://developer.mbed.org/compiler/#import:/users/samux/code/USBSerial_HelloWorld/

You have to enable "Update all libraries to the latest version" check box when you import the sample code and change the target to LPCXpresso1549. Also, please make sure you are using correct USB connector on the board which marked as "Target".

I didn't see any problem about USBSerial on the LPCXpresso1549.

If you are using LPC1759 (not sure it is your typo), LPCXpresso1549 USBSerial shouldn't work because their peripherals are not identical.

Accepted Answer

Thanks for help. I didnt updated last time now it works fine.Really appreciated Toyosama it would be a great debugging gate for my custom board.
