Energia Serial Port Issues on Linux

Recommended Posts

Can anyone help on this issue please ?

 

On Ubuntu 14.04 64 bit, I am unable to get the serial port to work with Energia 16  and MSP430G2.

I have exactly followed the install instructions for Linux : http://energia.nu/guide/guide_linux/

including setting udev rules.

 

The MSP430G2 can be programmed ok however any attempt to open the serial port monitor causes Energia to hang up/freeze.

 

FYI, I also have an Arduino board with the latest Arduino IDE which has no problems with serial output on this same evironment (and setting that up was a breeze).

 

It's a pity that getting Energia to work on Linux is so hard.

 

I have seen previous postings on this issue suggest a custom build of the cdc_acm driver; is that really necessary given Arduino works fine ?

 

Below is the output of dmesg:
