Hello All,

Can anyone tell me the technical reason behind not working condition of USB1 boot?

I was reading Errata for LPC4350 and i found out that USB1 boot is not functional and it is telling to USB0 instead of USB1.

I am very curious to understand limitation of booting with USB1.

Looking forward to reply

Thanks and Regards,
Sumit Nagar

Given that it is the errata, it is probably just a bug in the boot rom code. Afaik, the usb1 port works apart from this boot limitation.

Hello,

Thanks for your reply, it is understandable that there is a bug in BOOT rom code, but what is it? Why is it only on USB1 and not on USB0?

Is there any any future revision of MCU plan for resolving this BUG of Boot on USB1?

Thanks and Regards,
