MAC OSX MSP430 kernel extension not included in distribution

[pbrier]

The flash programmer does not work under MAC OSX. It reports:

rf2500: can't claim interface: Permission denied rf2500: failed to open RF2500 device

It seems you need a "codeless kernel extension" that is not included in the distribution See:

http://www.senslab.info/2010/11/installing-the-msp430-toolchain-under-mac-os-x/ https://github.com/colossaldynamics/ez430rf2500

I was not able to get it work under MAC OSX Lion 10.7 (64 bit)

Also, CDC driver is not included in MAC (Launchpad CDC is not compliant with spec) May need patched driver, like http://code.google.com/p/msp430lpcdc/ (include in dist?)

All you need is: http://code.google.com/p/msp430lpcdc/ Also available here: https://github.com/energia/Energia/wiki/Getting-Started

Please see this thread: http://www.43oh.com/forum/viewtopic.php?f=7&t=1591

If you have ez430rf2500.kext ("codeless kernel extension") installed then you will need to remove it.

Below is my log without the MSP430LPCDC.kext driver.

5/29/12 4:33:37.000 PM kernel: AppleUSBCDC: Version number - 4.1.15

Which in Energia gives me:

rf2500: can't claim interface: Permission denied
rf2500: failed to open RF2500 device

And this is with the MSP430LPCDC.kext.

Thanks. I'll have to check once I have access to a MAC again (I do not own one, but a friend of mine does, I tried to install on his system). It is wise to include this driver in the distribution, and make it easy to install it (automatically?)

[robertinant]

Ok, let me know if it does not work. Driver is already included in Energia 0101E0006. Closing this issue for now. Please reopen if you still have issues with getting it going.
