Do really exists a TWR-S08DC-PT60_LAB document which is cited on TWR-S08DC-PT60 Quick Start Guide?
More than 3 years later this original question, I was still unable to find it on the Freescale/NXP site nor elsewhere on the web.
I was pretty able to find the sw code project with no explanation on it and it was almost useless untill I succeed to find a video demo at:
http://www.nxp.com/video/an-introduction-to-twr-s08dc-pt60-demo-board:S08P-Eng500_VID
Fortunately the video was enlightening to understand the way of operation of the board with the Demo_lab code on it. In no other way I could imagine how to get information on the status via the PE Terminal Window or how to switch lab1 to lab2 and lab2-1 to lab2-4 through the potentiometer or the different operation of the accelerometer unit.
Really someone at Freescale made so much effort to design such a pretty complex little board with such a complicate demo Lab program without making a short manual on how to operate them? How did other peoples who acquired this board to operate it?
After studying the board schematic diagram also the question on how to connect the TWR_S08DC-PT60 daughter board on the TRW-S08UNIV module does not seem so obvious as in the answer on https://community.freescale.com/message/320591#320591.
In fact on the diagram there are components which may be supplied at +5 or +3.3V, jumpers to be inserted or not and at least 2 resistors which are warned they must be alternately populated in case of connection to 3.3 or 5V:
Really is it all so simple you have to do anything other than remove J10 BKGD jumper?

HI ECKHARD/All,
I've problem with debugging TWR-S08DC-PT60 board, when I was running sample code this was working properly. I wanted to test how Watchdog resets once timeout happens, so enabled WDOG and gave value to TOVAL as below. Once I tried to load this i'm getting attached errors,I'm not getting what mistake I did....
