So, i want to program a msp430g2553 microcontroller with raspberry pi 2. Since i don't want to use any IDE i would like to do it with clean C and terminal, without any external libraries like wiringPi etc. , just the microcontrollers one.

My questions are:

  • Can i do this with common interfaces like I2C or SPI?
  • Or should i use the JTAG interface to do this?

This is the first microcontroller that i am trying to program.I've seen that you can program an ATtiny85 with raspberry over SPI. Does all the microcontrollers have this functionalities or it is device specific.

  • \$\begingroup\$ You mean directly instead of using a programmer via usb? \$\endgroup\$ – Passerby Mar 2 '16 at 11:35
  • \$\begingroup\$ Yes, I want to do it directly without any external programmer device. Just by wiring the raspberry pi and the msp430. \$\endgroup\$ – Aleksander Dashov Mar 2 '16 at 11:40

    \$\begingroup\$ If mspdebug has been ported to the R-Pi, then I'd look at the EZ-430 or the G2553's Launchpad as a sub-$10 adapter between USB and the MSP430's SBW interface (a 2-wire subset of JTAG). \$\endgroup\$ – Brian Drummond Mar 2 '16 at 14:54

You can flash it via serial port, as @pjc50 suggested. Here is a part of a makefile I used for a msp430 project:

msp430-gcc -Wall -mmcu=msp430g2553 -o foo.elf some.c files.c and.c headers.h
msp430-objcopy -O ihex foo.elf foo.hex
msp430-objdump -DS foo.elf > foo.lst    # produces an assembler listing, optional
python2 -m msp430.bsl.uart -e -p /dev/ttyUSB0 -PV foo.hex -r

This requires the packets msp430-gcc,-binutils,-mcu,-libc and python-msp430-tools to be installed. You will need to connect RST and TEST lines to DTR and RTS as described in slau319 or this related answer.
