Schematics of the Olimex MSP430-H2618 Board


The 64 pins on the edges of the PCB are connected to the corresponding MCU pins. Hence, the following pinout of the naked MSP430-F2618 MCU chip matches the pinout of the header board:

Connect the board to a JTAG debugger supported by mspdebug; by default the Olimex MSP430-JTAG-Tiny (as shown in the picture above) is assumed, which is among the less expensive options.

If you are not using the Olimex MSP430-JTAG-Tiny (or a compatible programmer), set MSPDEBUG_PROGRAMMER to the correct value via an environment variable or as parameter to make. E.g. use make BOARD=olimex-msp430-h2618 MSPDEBUG_PROGRAMMER=bus-pirate to flash using the bus pirate.
You can power the board via the JTAG programmer by placing a jumper at P_IN. However, the JTAG programmer will only be able to provide a limited current. You may want to disconnect the header board from devices consuming a lot of power prior to flashing.
If the board is powered externally, make sure to place the jumper in P_OUT position, not in P_IN position.
A jumper in P_OUT is mutually exclusive to a jumper in P_IN. Never connect both at the same time.
Pin 1 on the JTAG connector has a small white triangle next to it and square pad, compared to the round pad used by all other JTAG pins.
The Olimex MSP430-JTAG-Tiny will fail to flash or debug the board until the latest firmware is installed. For that, install the Windows-only programmer software and update the DLLs files to contain the latest firmware as described in the website. The software will update the programmer upon launch.

Once the jumper is correctly placed in either P_IN or in P_OUT and the JTAG cable is connected just run

make BOARD=olimex-msp430-h2618 flash

Using the shell

stdio is available via the UART interface with TXD = P3.6 (pin 35 on the header) and RXD = P3.7 (pin 34 on the header) at 115,200 Baud.

The easiest way is to connect an USB TTL adapter (such as the cheap cp210x or ch341 based adapters) as follows:

TTL adapter Olimex MSP430-H2618
----------- -------------------
GND --- 63 (DV_SS)
TXD --- 35 (P3.7)
RXD --- 34 (P3.6)
