I have been using TI's ezMSP430 USB emulators. For only $20 they're a terrific way to get started. Along with that, getting the IAR Kickstart IDE with in-circuit debugging and C/C++ is great.
But, I decided to upgrade to the Olimex MSP430-JTAG-ISO since I fried at least one of the ez's.
I could not find any documentation at the Olimex site for the MSP430-JTAG-ISO. Ok, maybe it's new and I should just go look at one of their other devices, but to no avail. So for those of you who are wondering about this, I suggest going to TI and downloading their document: SLAU138E. (Note to self: maybe this is telling you something)
The TI document does very well to describe their similar product and shows schematics for interfacing the standard JTAG connector (14 line ribbon cable terminated with 2x7 plug) to both the newer Spi-Bi-Wire "2 wire" interface (Vcc, Gnd, Clk and Data) like the little ez430 uses or the older JTAG interface with more signals.
That solved, I obtained the drivers for the Olimex ISO (version 1.011) and installed them without any issues.
When I plug the device in, my PC recognizes it.
PROBLEM
After carefully checking and rechecking settings in IAR Kickstart, I am unable to get the Olimex MSP430-JTAG-ISO to work at all. It's Green LED is on. When I attempt to go into debug mode, IAR always gives the message "FATAL ERROR Failed to initialize device. Session aborted!"
The settings in IAR I am using are:
Connection: TI USB FET
Can anyone offer any ideas as to what I am doing wrong?
To Olimex: maybe writing English language documentation is not your strong suit, but that's OK. Here's your chance to shine at customer support.
