Problems with ColdFire_Lite.mcp for M52235EVB

[McGregor]

Hi,

I am trying to run ColdFire_Lite.mcp (I think it is a web server example) in my board but it is driving me crazy!! I am working with CW v6.3 for CF Special Edition, CF_Flasher and USB_ML_CF. In the last two days I think I have seen all the errors you can imagine.

First of all, I got the error "Exception vector name: Address Error" when I tried to debug the program. Thanks to a thread of this forum I realized that I had to use CF_Flasher to upload the *.s19 file that CW generates when you make the project (that I think is example_flash.S19).

While I was doing that I got the error "Could not initialize BDM device" and thanks to a thread of this forum again I fixed it by copying unit_cfz.dll in the folder windows/system32.

And after doing that, I got the error "PEMicroProtocolPlugin: No USB connection found". I had a look in the forum again and I read that I had to uninstall the drivers of the USB_ML_CF and install them again. I did it and then the USB_ML_CF worked pretty well but CW still gives me this error when I am working with this project (the "Hello World" project seem to work well although today CW has given me the same error when I have tried to debug this program!!).

Is there any documentation (a tutorial or something like that) about how to build and debug this project step by step?

Has somebody any idea about what I have to do to be able to test this project? And how can I do it?

Help me as soon as possible please, because we are loosing too much time!!

Thanks in advance!

Best regards,

Grego

Hi Grego

I can't help with the ColdFire_Lite.mcp but I (and other collegues) have experienced initial problems with the debugger, including the need to reinstall the driver. Once it is working correctly it is however a very good tool, as is CW6.3 so stick with it because it will be worth the effort.

What I can offer is the uTasker solution which is free of charge for educational and other non-commercial use. It is full supported by email and documented. Check out the tutorial to the demo project here.

http://www.utasker.com/docs/M5223X/uTaskerV1.2-Tutorial-M5223X.PDF

The demo project includes most things which are needed in a project (from IP through TFTP, dynamic HTTP, FTP, SMTP to high performance TELNET). It includes drivers for UART, I2C, CAN and various other things like high resolution timers and DMA integrated in the operating system. It has a file system in internal FLASH or external EEPROM via SPI and can be configured for immediate use of matrix keyboard and LCD displays. It can be fully simulated in the unique uTasker simulator and the project can be moved between the Coldfire M5223X and the HCS12 M9S12NE64 by setting one compiler switch. It also includes a powerful boot loader enabling complete software uploads to the board via the Internet. The debugger is in fact very rarely needed for normal development work...

You can find more details at the web site below.

Hi Mark,

thank you very much for the info!! We had been studying the option of start working with uTasker (and it seems really good!) but finally we have decided to check first this option.

Thanks anyway!
