MSP430 Upload fails on Mac, old MSPdebug?

[scandey]

On Mac OSX 10.14.6, attempted to send a simple Blink file to an MSP-EXP430FR5739 (one of the supported boards) from PlatformIO IDE extension installed into VSCode as recommended.
Everything appears to go well until sending to the actual board: code builds correctly and the upload feature automatically downloads and builds MSPdebug. There then appears to be a permissions error connecting with the MSP430:
Trying to open interface 1 on 025 rf2500: can't claim interface: Permission denied rf2500: failed to open RF2500 device

While I am opening a similar ticket with MSPDebug, I note that they are a whole version ahead (0.25) of the automatically downloaded MSPDebug in PlatformIO with some suggestions in old issues that the upgrade have helped with this issue. Is it possible to update the MSPDebug version for PlatformIO or at least temporarily adjust what version is downloaded for my installation?

Thanks!

I recognize that error. Did you install the Energia kernel extension here: energia/Energia#55?

Also, I need to add a pull request there, but I discovered a bug where I had to edit the Info.plist of the kernel extension because the distributed plist didn't work (I'm macOS Catalina, so it might be something weird with Catalina). If that doesn't solve the issue for you above, you can try editing the Info.plist so the similar section looks like this:

	<key>DTXcode</key>
	<string>0420</string>

If I remember correctly I merged the debugIntf with the existing MSP430LPCDC key and it started working better.

I have same issue on OSX. The driver is installed. I am using msp430g2553 launchpad. It used to work. It looks like happened after update to BigSur :/

[hellvesper]

the problem looks like fixed in mspdebug version 0.25, anyway it works on Monterey as standalone app, but platformio still using mspdebug v.0.24

wow guys, I just solved this problem on Mac (Monterey 12.6.2). It seems platformio's mspdebug is old version(v0.24), and i find that my another mspdebug installed by macports, which is v0.25 works well. So i create a symbolic link to cover the platformio's old version. And it WORKS!

Below is what i did:

1. install mspdebug by macports; seems homebrew repo doesn't have the mspdebug pkg...
2. try if the standalone mspdebug is work well by exec "mspdebug rf2500" in your terminal; if it works, go head
3. rename the platformio's old version as a backup; the old version path on MacOS is "~/.platformio/packages/tool-mspdebug/mspdebug"
4. create a symbolic link to cover the old version in same path. on my mac, the standalone mspdebug installed by macports path is /opt/local/bin/mspdebug, so the ln cmd is "ln -s /opt/local/bin/mspdebug ~/.platformio/packages/tool-mspdebug/mspdebug"

now try to upload your hex again in platformio and see if it works.
Good luck!

yeah, but we want them to update this SDK, and debug in platfromio doesn't work properly with mspdebug v.0.25, I think it should be fixed from platformio team
