Amforth with Raspberry PI

No, this recipe is not abot using amforth on the Raspberry PI, but use the RPi as the development platform for the microcontrollers it supports.

Compiling amforth for the Atmegas requires the Atmel Assembler which runs only on some, widespread however, platforms like Windows and x86 Linux with wine. It is however possible to use the avrdude program to flash the controller.

The MSP430 variant got the full toolchain working. The necessary tools naken_asm and mspdebug work fine.


The setup has been tested with pidora, other linux’s should work the same way.

The mspdebug utility requires direct access to the USB port. This can be either achieved by running it as root or (better) by adding a file /etc/udev/rules.d/46-TI-Launchpad.rules with the content (a single line)

ATTRS{idVendor}=="0451", ATTRS{idProduct}=="f432", MODE="0660", GROUP="plugdev"

Restart udev afterwards and re-plug the launchpad. The user account you’re using has to become a member of the plugdev group. Check with id, re-login if necessary.

The naken_asm is installed from the sources. Just follow the instructions.

Other tools are the make utility (or ant), the editor and the terminal program.
