I know this has been beaten to death, but I still can't resolve this issue!
I have used these interface to program the chip on the target previously.
Now I get programming errors (code 0x03) every time I ask it to do something.
Weird thing, if I ask it to read the voltage, it fails. But if I ask it to read the device ID, it successfuly reads the voltage, but not the device ID!
It's almost like (in simplistic terms) there is a missing CR (or other terminator) at the end of the data, and the software times out.
I'm running Win7 professional. Same results on two different PCs!
Has anyone reliably solved this problem??
