trying to get the GoodFET running on mac


# download mps compilers
brew tap tgtakaoka/mspgcc

# prepare folders

sudo mkdir /opt/homebrew/lib/msp430 /opt/homebrew/lib/msp430/lib /opt/homebrew/include/msp430 /opt/homebrew/include/msp430/include
sudo chown -R $(whoami) /opt/homebrew/lib/msp430 /opt/homebrew/lib/msp430/lib /opt/homebrew/include/msp430 /opt/homebrew/include/msp430/include

# run install 
brew install libc-msp430 gdb-msp430

Found a good starting point to talk with the MSP430, but sadly it runs into a weird bootloader password issue.

goodfet.bsl -P ./goodfet.hex --fromweb

aha! So the tutorial uses a capital P where the flag should be a small p. Or not, maybe the password stuff is set somewhere else or while compiling. writing the ./prebuilt firmware worked.

board=goodfet42 goodfet.bsl -p goodfet.hex

Well that wasn't really a solution, but somehow I got it to except the firmware, probably by using the "fromweb" flag for it, where it wasn't confused by all that.

Unfortunately, I can’t implement a similar task on my Mac. Perhaps the problem may be with my MacBook or the software. I find the computer I use to be powerful and productive enough to handle a wide range of tasks. However, since I am not a very experienced user of this model, to understand all the nuances I may need such high-quality manuals as https://setapp.com/how-to/kernel-task-high-cpu This way I can optimize my workflow and use all the features of this device more efficiently. In this case, I think I will be able to cope with this task.

Are you sure? yes | no

I think I forgot to finish what made it work in the end and now two years later I'm wondering myself

Are you sure? yes | no

Interesting decision, but it surely needs to be improved

Are you sure? yes | no

which decision do you mean exactly?

Are you sure? yes | no

but first, we must build a goodFET42
