Hi all,
At our company, we have two generations of motorcontrollers. The "old" using the F28062. We're currently using an Spectrum Digital XDS200 with a conversion board to program it.
For the "new" motorcontroller, we're using the F2800137. We've developed the code initially on the LAUNCHXL_F2800137, with of course using the onboard debugger.
Now, we've created a conversion print from the LAUNCH board to the actual hardware design of the F2800137 motorcontroller. Using a 12 pin jtag header.
The old controller uses a 10 pin jtag header. The conversion print from the LAUNCHXL is a direct connection from the 14 pin jtag header to a 10 pin, and 12 pin header.
Now here is the issue. Programming, debugging, reading memory, etc, works wonderfully and reliably on the F2800137 hardware design (the "new" motorcontroller).
However, it does not work with the F28062 board. All using direct JTAG connections.
What are we missing here? The JTAG connections can be direct right? Since that's how it was using the Spectrum digital probe, and the F2800137 probe.
Sometimes we get a 'SC_ERR_PATH_BROKEN', sometimes a reset error, and sometimes no connection at all. There is no real correlation. The F2800137 always works.
We're trying to resolve this since we want to use a single debugging probe for both devices. The LAUNCHXL board will also be used as a functional tester for the software department. So the DUI will be programmed using the on board XDS110, and tested using the actual F2800137 processor on the LAUNCHXL board.
Thanks in advance!
