LPC-Link 2 not recognized any more...

I have this LPC-link 2 that suddenly doesn't work neither with LPCxpresso or Flash Magic.

On Device Manager it appears as just 'LPC' and curiously its PID and VID are:

USB\VID_0008&PID_000C&REV_0100

That I think is not the right values, VID for NXP should be 1FC9, right? Could it be that it got corrupted?

I am thinking now if there is a way of reflashing it

Hello Juan Abelaira,

About the lpcscrypt command, you also can refer to this document:

Have a great day,

Hello Juan,

   When you use the Flash Magic to download the debugger code, do you remove the block between JP1?

There is no jumper link on JP1, I have it on JP2 to power the target (sometimes)

Hello Juan Abelaira,

   Now, please follow my steps to check the LPCLINK2 detail problems:

1. Remove the jumper on JP1

2. Open Boot LPCScrypt under your lpcscrypt

3. Input: cd bin

4. input: lpcscrypt querypart

   just check whether the LPC4370 have problem or not.

5. input: lpcscrypt queryflash

   Just check whether the on board external flash have problem or not.

 This is my test result:

Please check it at first, and give me you screenshot.

Waiting for your reply!


Have a great day,
Kerry

Hi Juan Abelaira,

     When remove the JP1, and open device and printers in the control panel, can you find the LPC device?

If the LPCscript still useless, I think your on board LPC4370 maybe damaged, not just the software lost problem.


Have a great day,

I have a second Lpc-Link2, I'm wondering if it's possible to reflash the faulty one.

I learnt lpc-link2 gets a new firmware when connected to LPCXpresso, a physical disconnection when doing that may have left it with the flash corrupted.

Problems I have with this repair way:

- Can't find the firmware images for lpc-link2 (is it only the bootloader needed?)

- Can't choose LPC4370 as the device.
