Hello everybody,
I'm having the well-known, above mentioned error on a PCB with the MSP430F5438, some capacitors and a 3.3V LDO only (no external crystal). I also tried different version of the PCB with crystal, followed the exact guidelines in the JTAG manual, read all the posts about this error here and tested for weeks. Nothing works.
Here's the JTAG-part of my PCB:
The connection of J70 to the USB FET is a 1:1 connection (for the above connected signals only).
Here's what happens what I'm listening to the conversation between MSP and PC:
Unfortunately I'm not sure anymore about which channel is which signal, but D6 and D5 correspond to RST and Test, D4-D1 to the 4 data/clock/MS lines.
Everything works perfectly with the Experimenter Board, using the same debugger mentioned above!
I'm really frustrated and don't know anymore what to do - I even tried different board designs using both TQFP and BGA packages.
Thanks for your help!
