I´ve bought the TWR-S08DC-PT60. So far I tested it as standalone board and it works. After a quick look at the schematics at http://cache.freescale.com/files/soft_dev_tools/hardware_tools/schematics/TWR-S08DC-PT60_SCH.pdf?fpsp=1
I am not shure if it is possible to connect it to the TWR-S08Univ board without doing some solder work to populate or depopulate some Resistors.
The next question is which OSBDM to use for the Daughtercard ?
Any help is recommended.
