Hello,

I am new to LPC boards and LPCXpresso. I am trying to program a simple example project to the LPC1788-32 Developer's kit board. I am following this tutorial: http://mc2.unl.edu/2013/10/04/lpcxpresso-hello-world-and-breadboard-led-blinking/#fn1-154

Unfortunately, I am getting this error message:

[img]http://s16.postimg.org/b6gu2iwb5/Screen_Shot_2014_05_23_at_9_45_33_PM.png[/img]

I have tried both USB ports of my Macbook Air and also an external 5V power source.
Additionally, as I have not found the information about which micro-USB board port I should connect to power/program the board, I have tried all possible combinations on the three micro-USB board ports (see image bellow)

I have no idea why it is not working. Is there need for installing any drivers? If not, what could I do to get this to work?

Thank you all,
Enzo

I could now find which micro-USB is used to power/program the board. In fact, I downloaded Flash Magic and I was able to program the LCP1788 board. But I still can't program the board using the LCPXpresso software. Any idea?

Which LPC-link are you using and how did you connect it?

Did you read the User Manual?

4.23 SP13: Power Supply

The power supply on the board is straight forward. There are three powering sources:
1. +5V DC via 2.1mm power jack (J24). Center pin positive. There is also an alternative connector (J23) for this powering option.

2. USB powering via the USB-to-UART Bridge connector (J25).

3. +5V DC power form the PoE (Power-over-Ethernet) connector (J12)

Yes, I have took a time and read about how to program the board. But unfortunately, the User Manual only shows how to program using Flash Magic tool. And I do not see it informing about LPC-link. What would be that? Is it necessary for the programming step?

This boards are available since 2011 and this manual isn't very up-to-date....

Chapter 5.4 is talking about SWD interface.

What you need to use LPCXpresso as Debugger is a LPC-link or LPC-link2 and a ribbon cable for J7 :)

How about reading the LPCXpresso manual?
