LPC ISP Programmer

lorenzogalbiati — Tue, 27 Sep 2022 14:37:27 GMT

Hello,

for my job i have devoloped an electronic product with LPC1317 controller and unfortunately our LPC2K programmer from FDI has broken.

This microcontroller doesn't have a JTAG programming port, only ISP, and I can't find another usb programmer to be used with Flashmagic software.

Can anyone help me? I need to solve this big issue for my job; our production could be stopped because of this problem.

Best regards.

Hi @lorenzogalbiati,

I would suggest making your own SWD connections, since this board has the necessary pins for it, and utilizing any debug probe (MCU-Link, LPC-Link2) that supports SWD.

You can look into this community post explaining the Design Considerations for Debug.

I hope you find this helpful!

Best regards, Julian

Good morning, thanks for the answer but this is not possible on my board.

I have used SWD pins for another function and they are not connected in a SWD connector so I can't access them.

I have read that SWD is only for debugging while I need a flash programmer for production, not for debugging.

I suppose there are many other designers with my problem so I wonder if there is another solution.

Best regards.
