Mspdebug Can't receive data

Question

I am trying to learn to program microcontrollers. I am starting with the msp430 and I have installed mspdebug 0.18 and mspgcc 4.5.3. I would like to load a simple program onto the device for testing, but mspdebug cannot get pass erasing the device.

Device: MSP-EXP430FR5739  
Computer OS: Ubuntu 12.04 LTS  

Error Messages:  
Trying to program device:  
(mspdebug) prog led.elf  
Erasing...  
rf2500: can't receive data: Resource temporarily unavailable  
fet: erase command failed  

Trying solely to erase device
(mspdebug) erase  
Erasing...  
rf2500: can't receive data: Resource temporarily unavailable  
fet: erase command failed  

Output of dmesg after unplugging and plugging in the device:  
[ 1537.370302] usb 3-2: USB disconnect, device number 3

Answer 1

This has to do with erasing not working (or at least not working as usual) on the FRAM chips. You should update to the latest version of mspdebug ( http://mspdebug.sourceforge.net/ ) which takes care of that.
