Good! Which ARM Toolchain have you used for your build?
Actually the same GCC ARM toolchain I'm using for my "slow-moving" Stm32Basic hobby project on STM32F103C8T6 "blue pill" board:

Code: Select all

sudo apt-get install gcc-arm-none-eabi binutils-arm-none-eabi gdb-arm-none-eabi

Maybe we should create a separate HowTo thread?

I'm going to do better than that.

When I get a couple of minutes I'm going to set up a "developer" sub-forum under "DM42".

@SwissMicros:
I don't know,if other places like https://www.swissmicros.com/dm42/tools/ have to be checked.

There is now a community-driven forum for DM42 firmware, where questions about the toolchain, methods, tips & tricks can be discussed.

Please note that support in this forum from Swiss Micros staff will only happen as time permits, so not that often! This is intended mainly as an area for the community to meet.

This is absolutely outstanding. I'm excited. Not sure how capable I am of contributing much more than enthusiasm though

Hi Logan,

Enthusiasm is one of the greatest contributions one could give.

Only my two cents, your mileage may vary...

Cheers!

Thomas,

I think the key question for me is:

Are you satisfied with the final result?
Or do you feel that there are still outstanding issues?
It took me a while to take a look at it, my apologies for that -- I was on vacation when the release was made, and while on vacation, I caught a nasty cold that I'm still not recovered from -- but yesterday I finally installed 3.7 on my DM42, and downloaded the sources from github and built the pgm from them.

I haven't looked at everything yet, but from what I have seen so far, SwissMicros did a good job with this. It is possible for DM42 users to customize and build their own firmware now, and that was what the whole controversy was all about.

The only remaining issue that I could imagine existing would be if they put code in the OS part that belongs in the Free42 part, but I don't think that's the case. Again, I haven't looked at everything yet, but it looks like the OS API defines functionality along lines that are reasonable for an OS, namely, hardware abstraction, including filesystem and display access.

So, to summarize, I'm happy with the 3.7 release. Well done!

That's great to hear! So there's no remaining acrimony between you and D & M? If not, you three can move forward again and we will all benefit.

If I buy someone a drink to congratulate them, is it a Mazel Tov cocktail?
