Failed to compile the blinky example

[lpcware]

Content originally posted in LPCWare by xultz on Mon Apr 14 05:22:13 MST 2014
Hello.

I'm new to LPCxpresso, I have some experience working with LPC2106 using GCC as a compiler.
I downloaded the LPCxpresso for Windows, and downloaded the examples. I would like to compile the blinky example and try to run it on a mBed LPC2168 board, just to test it.
I didn't change anything in the code. What am I doing wrong?
Thanx for any help!

The compilation failed, with the error messages:

Thank you very much, R2D2, I'll test it (tomorrow)!

Another question I have, the compiler generates a .axf file. If I click on it I have the option to create a binary file with .bin extension. Is that the file I must copy to mBed so it can run the firmware?

Unfortunately this bin-file  isn't checksummed.

You should use post-processing to generate a bin with checksum.

See: http://www.lpcware.com/content/faq/lpcxpresso/post-processing-linked-application

Your 'Post-build steps' should look like:

arm-none-eabi-size "${BuildArtifactFileName}"; # arm-none-eabi-objcopy -v -O binary "${BuildArtifactFileName}" "${BuildArtifactFileBaseName}.bin" ;[color=#f00] # [/color]checksum -p ${TargetChip} -d "${BuildArtifactFileBaseName}.bin";  

Just remove the '[color=#f00]#[/color]' and the correct bin file is created...

You got it! I don't know how and when, I compiled the blinke in Release mode, and the libraries where set to Debug mode. I did a make clean in all the three projects, switched all to Release mode, and recompiled them, and now it worked.

Thank you so much for your help!!!

You're building your project in Release mode, did you build your libraries in Release mode also?

If so, check your Libraries->Settings again...

It all worked for me. Suggest you read the section on manually creating links to library projects in the FAQ:
http://www.lpcware.com/content/faq/lpcxpresso/creating-linking-library-projects

Thanx for the reply

TheFallGuy, yes, I did read the documentation and I followed the steps there, and I am stuck in the step "Building an Example" when I try to build the Blinky example. It is not my intention to waste anyone time, I'm seraching for help here because I followed the tutorial and it didn't work, and I don't know what to do.
R2D2, yes, I imported both libraries, and built them, without errors. But when I try to build the example code, it fails.

On the link below it is possible to see an screenshot of the LPCxpreso with the error, and it is possible to see that I imported all libraries from LPCOpen.

If you follow that, you won't waste your time, our ours.

What's not clear there  :quest:

Your linker isn't finding this 2 linked libraries.

Did you import and build them?

Thank you very much for the reply.

Maybe I'm drinking too much coffee, I though LPC1768 as the mBed processor, and type LPC2168, and I have no idea where that code come from :)
I understand that probably (I didn't check it yet) I'll need to modify the code to change the port for a led in the mBed board. My first duty was trying to compile the example code as it is, and is successful, modify it to work on the mBed, but it failed on the first step.
So, I downloaded all the LPCOpen examples.
I built the lpc_board_nxp_lpcxpresso_1769 code, and here is the result:

There is not an mbed "2168" board. I assume you mean and mbed LPC1768 board.

It looks like you have tried to import the LPCOpen "periph_blinky" application. A few things to note:

[list]
  [*] When using LPCOpen, you must also import the "chip" and "board" library projects from the zip file: lpc_chip_175x_6x and lpc_board_nxp_lpcxpresso_1769. This is described in the documentation.
  [*] LPCOpen does not explicitly support the mbed board. Basically this means that the pinouts used by the examples may not actually match your board - in other words, the blinky will probably not blink the LED on your board. You will need to modify the "board" library to define what the pinouts are. The "lpc_board_nxp_lpcxpresso_1769" project is setup for the LPCXpresso 1769 board (OM13000).
[/list]

Your target MCU is a LPC2168 and you are compiling for a LPC175x or LPC176x.

You used a wrong sample.

Anyway it should compile so check if include path's are correct within LPCXpresso.
