0 SWD devices found lpc802

[karmit1998]

I am using the lpcxpresso802 board. Everything was working perfectly fine until I got the "0 SWD device found error". Now, I cannot access my device through the debugger. I tried restarting the device, the software and even the PC but does not work. Now the device is stuck in the previous configuration. 

I also tried to switch laptops and different projects. But nothing works.

Is there a way to solve this either by resetting the device or some other way?

Hi Karmit Patel,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
According to your introduction, it seems that the LPC802 be locked, I'd like to suggest you to try to erase the whole flash via ISP mode to recover it.
Flash Magic is a PC tool for implementing a variety of flash operations on NXP's MCU via using a serial or Ethernet protocol, so please give a try.

Have a great day,
TIC
