LPC-Link 2 not recognized any more...

juanabelaira — Mon, 11 Sep 2017 09:18:56 GMT

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,

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

Have a great day,
Kerry

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

Hello Juan Abelaira,

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

Chapter 4.

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.

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,
Kerry
