How to program the ProStart LPC1114 with LPC's FlashMagic

Hi all,

I hope I posted to the right forum, but I was given a ProStart LPC1114 (https://www.coridium.us/coridium/shop/b ... 0-prostart), and I am having a hard time of programming a piece of firmware using LPC's FlashMagic tool.

The ProStart LPC1114 does not come with a USB-serial chip. So, I basically hook it up with a USB-serial breakout board. The FlashMagic tool recognizes the USB-serial's COM port immediately/automatically.

But when I attempt to program a piece of firmware, I always get connection error that fails to autobaud. I went to the web site that FlashTool suggests me to go to and read the reasons of failure autobauding.

I checked my RX/TX connections. All is good. So, I added a button (S1) to the board.

It looks like I need to get the bootload started somehow!

Thanks for any help!

There is a 'loadC' hole near the corner - it needs to be connected to GND to program/receive the data. the hole next to it iwth the thick trace
Are you doing Basic or bare metal?? - sounds like bare-metal,

Thanks for the answer. Attached is the image. I drew the red line to the Load C hole/pin. You are talking about that pin, correct? That pin is traced to the Cn pin of the 6-pin header which I drew the other red line pointing to it. So, then I connect the Cn pin to GROUND then?

And I do bare metal stuff with the LPC1114.

Thanks!

Woot! That did it! Connect the "Load C" pin to GND pin will get the LPC1114 programmed at 115200 baud via FlashMagic successfully!

THANK YOU @olzeke51!!!

Thanks olzeke for answering the question, did not see it go by.

How are you generating the hex file? Just curious.

BTW that load C pin is also driven by our serial USB dongle, so that the load hex of MakeItC handles the boot mode automatically. You can also modify other USB dongles to connect RTS to load C
