LPCXpresso 54608 not recognized

[yashbohra80]

I'm using LPC 54608 board for the first time, Initially out of the box demo was working fine, and also only for once it worked as mass stoarge device using Full speed port then as per instructions i deleted the firmware file and while copying the other file , all of a sudden one dialog box appeared saying that device disconnected and some malware issue ..something like that . After that i am connecting board via usb cable neither demo is running nor it is recognized as mass storage device.

Hello Yash, I hope you're doing well!

To use the Link2 debug probe you need to make sure J1 is in the correct setting, if you're trying to debug the using the on-board Link2 Debug Probe or an external debug probe, you should leave it open. If you instead want to debug an off-board target MCU, you should shunt the jumper. For more information, you can check Table 1 of the LPCXpresso546x8/540xx/54S0xx Board User Manual, located here.

If you have any further questions, please feel free to ask.

Best regards,

Sebastian
