New to freescale programming MC56F8013

Hi

I've been working at a company for the last 8 month and have just been asked to finish a project that somebody else started sometime ago. I'm have never programmed a freescale device before but I'm quite interested to learn to see what advantages/disadvantages the device has to offer over other microcontrollers that I have experence working with. The guy who started the design has moved on and

left some information which I gone through.

The hardware has been designed which is working correctly

Some software has been written for the device which I wanted to test. But I cannot communicate with the device. The device is soldered to a built pcb and commnicate via the RS232 connection on the device.

The error message is:-

"CCS Protocolplugin: CCS : Cable disconnected"

The serial port is working on the laptop ok as there is another programm for downloading values to the device which is working correctly. But I cannot program the device via the "codewarrier devlopment enviroment "

There is no one with any device programming in the company and the laptop was wiped, of any previous project.

What I/O setting do I need in code warrior to commnicate with the device via RS232 ??

All help greatly recieved Dave !!

Thanks Tom for the quick reply

I've fixed the problem now. It is connected via a jtag 25 pin connector and now programmes the device correctly. The RS232 is only being used for transfering variable between a small program on a laptop and the host device.

I found a load of connector in a box along with a training kit for the device. !! which will come in useful

Cheers Dave

How does the "program that downloads other values to the device" accomplish this? Through what sort of cable? Is it a Flash programmer program?

What are the settings for ColdFire debugger? Type Alt-F7 in CodeWarrior, which should bring up the project's settings panels. Click on a debugger panel on the left-hand side of the settings window to bring up the chosen settings panel. Study these settings. In particular, you want to check the Remote Debugging settings panel and see what's selected under the Connection option.
