Hi nikhilmishra 

There are several possibilities that cause the issue, please check following two points.
- LPC1768
Where did you purchase the part?
Please provide the silk print picture of both your current LPC1768 and 2020 manufactured part.

- PCB
Is the PCB manufactured in 2020 the same as the current one?
To identify if the problem is caused by PCB circuit or LPC1768, do LPC1768 A/B swap on old and new PCB. How is the LAN working?

 

Thanks,

Jun Zhang
