Define msp430 toolchain for raspberry pi

[isman7]

Hi!

We are running on a robotincs Hackathon this week in Barcelona and we want to use platformio to quick prototyping of a given robot which has to boards, an MSP430F5529 based custom board, given to us by the organization and a Raspberry Pi 2.

Our idea was to use the Raspberry Pi 2 to cross-compile the firmwares for the MSP430, then the first idea was using PlatformIO, but this error came:

Error: Could not find a version that satisfies the requirement '~1.40603.0' for your system 'linux_armv7l'

Is it possible/easy to add a custom package to PlatformIO? Because there exist packages to crosscompile for theese boards from raspbian (linux armv7l). Where we should start to implement it.

Best regards,

Isma
