LPC-Link2 not working

jameshsu — Mon, 07 Dec 2020 01:20:12 GMT

Hi NXP:

I have a broken LPC-Link2, with LPC4330FET100 controller, which can not be recognized on PC.

It seems the bootloader is broken, could you provide the bin file of bootloader and latest FW of this LPC-Link2 version?

Hello ,

To program a standalone LPC-Link2, first of all ensure that jumper JP1 is NOT fitted so
that the probe will be DFU bootable at power on.

Then connect the board to your host computer over the debug link USB connector and in
a command shell run either:
<LPCScrypt Install Dir>\scripts\program_CMSIS
or
<LPCScrypt Install Dir>\scripts\program_JLINK
Note: For Windows users, shortcuts to these scripts are available from the LPCScrypt entry

About detail, you can refer to User Guide for LPC-link2, part 5 Programming(LPC-link2), I also attach it

for you.

Regards,

Alice
on the Start menu.

Hi Alice , I already tried, but it dose not work.

I did not see any device when I plug LPC-Link2 to my PC, the USB function of LPC4330 is abnormal.

I think the last user had erased or program the LPC4330, so I need the bootloader srec file to program it again.

Hello

"I think the last user had erased or program the LPC4330"

-> I think it is impossible, because the this is ROM bootloader, customer can't access it, we also can't

program it.

If your board can't enter DFU mode, maybe your board is broken, you can check the DUF pin.
