USB DFU UUID or OTP Access

[travis_scott]

We are using LPC54616 MCUs in a product. We want to enable field upgrades of these devices using USB DFU. Is it possible to read the OTP (which is set with serial number during production) or the MCU UUID through the USB DFU bootloader in ROM? That way we can uniquely identify the product.

Thanks

Hi Travis,

The only options you have to read the UID is the IAP ReadUID command or the USART ReadUID command through ISP.

I recommend you to check chapter 5.6.9 and 5.4.5.15 respectively in the User Manual.

I hope this helps you.

Have a great day,
Felipe
