Other Parts Discussed in Thread: CODECOMPOSER
Tool/software: Code Composer Studio
I've got new board in and I cannot get it CodeComposer to detect it. I'm jumping 3.3V on to the board, so the only parts populated are the JTAG connector and the MSP430G2755 microcontroller. The current draw looks reasonable, 84uA @ 3.3V. At first pin 1, TEST, was not connected, but I've jumped that to 3.3V to enable the JTAG pins 35-38.
I've double checked the following connections
Pin | Connection |
1 - Test | jumpedto 3.3V |
2, 16 - Vcc | 3.3V |
4, 15 - Vss | GND |
35 - TCK | |
36 - TMS | |
37 - TDI | |
38 - TDO |
I've hooked a scope up to the JTAG lines. TCK looks like a clock, and TDO has a burst of data.
What am I doing wrong? I need help.
Thanks
