Hello
We are working on a project with mifare card. After to buy the product "Pegoda Evaluation Kit MFEV710", we try debug the project that comes in the CD (pegoda2_fw_src_v2_2.zip) on the IDE "LPCXpresso v6.1.0", but we can't do it. Apparently the file is downloaded to the micro (LPC1769) , but when we try debug it appear the message "No source available for "0x1fff0ba4".
Best regards, Mauricio

... now i can debug the code.

Good to hear that...

Hello,
I modified the linker scrip (rom (rx) : ORIGIN = 0x00000000) and now i can debug the code.
Thanks, Mauricio

Could to be that this project was thinking for download it in a microcontroller with an bootloader, and not over an empty?

Yes.

Does your project use 'managed linker script'?

That's the best way to define your memory (and start with flash address=0).

I am following the application note "AN11002 Pegoda Toolchain Information" ("http://www.nxp.com/documents/application_note/AN11002.pdf"). In this application note explain two option of programing enviroment, LPCXpresso and OpenSource. When I import the project "pegoda2_fw_src.zip" over LPCXpresso, appear two option for compiling:
1- Pegoda 2 (LPCXpresso 4)
2- Pegoda 2 (Open Source)
Then I select the option 1 and the project compile is OK (apparently).
I don't know is the problem is:
1- The configuration is for LPCXpresso 4 and not for LPCXpresso 6.1
2- In the project have prohibited the ejecution step by step of the code.
3- Like you said, the configuration of the project is wrong.

Could to be that this project was thinking for download it in a microcontroller with an bootloader, and not over an empty?

So which file did you flash? pegoda3_fw.hex?

Your linker script is starting where?

Quote:
MEMORY
{
rom (rx) : ORIGIN = 0x00005000, LENGTH = 512K
ram (rwx) : ORIGIN = 0x10000000, LENGTH = 32K

ram1(rwx) : ORIGIN = 0x2007C000, LENGTH = 16k
ram2(rwx) : ORIGIN = 0x20080000, LENGTH = 16k
}

That's obviously wrong. Flash is starting at ORIGIN = 0x00000000.

This is no LPCXpresso project, so I'm not sure what you are doing. (Would suggest to create a new LPCXpresso project and add required files there).

Anyway, if you flash this file the required vector table (starting at address 0) is empty and debugging will fail because LPC1768 will start in ISP mode without it....

I attached the project that come with the development board.

Either your vector table isn't valid or there's no checksum.

Read UM: 32.3.1.1 Criterion for Valid User Code

Perhaps you want to post your project or at least your AXF file....

Hi,
The debug log it is the following:

In effect, when the load is finished, the microcontroller remains in bootloader mode. I no clarified that i'm working on a alone board LPCXpresso1769 without other aditional hardware (not in the "Pegoda Evaluation Kit MFEV710").
Now, I connected the port pin 2-10 with a pull up resistor to 3,3V and the result is the same.
sugestions?
Thanks, Mauricio

I'm not familiar with this kit or its demonstration code. But it sounds like the download is not succeeding and you are ending up stuck in the LPC1769's bootloader.

Can you please post the debug log that is generated when you try to start a debug session….
