RPI3 baremetal trying to be a good tinygo citizen

Ok, I tried to take in all the suggestions about organization and it resulted in this.

I still have two questions about how to get this integrated "right":

  • I am getting undefined symbol errors of _bss_start and _bss_end when I try compile anything that uses this target. I pretty much mimicked the code in another target (fe310) and in runtime_rpi3 (line 108) you can see that I am defining these symbols. I also have these being set in rpi3.ld so I thought I did all the things...

  • What is the correct way to "hook up" to the garbage collector? Is it going to work with 64bit pointers and integers?

The garbage collector should work. It gets the pointer size by checking the size of the type of heapStart. It should be able to find the globals I think.

OK, so is this PR meant to replace #584 completely? If so perhaps that PR should be closed.

H @iansmith looks like this PR is getting close to landing. Any chance you might be able to address the last remaining feedback that was provided by @aykevl soon? We have a new release this week, would be great to include this PR.

Thanks!

I am sorry guys, I have JUST started a new job (monday) and I'm not sure how much free time I will have before this weekend.

Pinging to hopefully re-up with intentions of helping it land in time for the next release... :)

Greetings, I am on the lookout for RPI3/4 baremetal solutions for tinygo and came across this. It appears to be stalled :(

Can anyone say if there are other places to look for support in this regard [or] was this PR our only hope?

Thanks in advance,

-DF

Yeah, it's stalled. I just haven't had time to really put many cycles into it.

If you want to push it forward, I can probably review PRs and test on RPI3 and so forth,

sorry, ian

FYI: I have started looking at this to see if I can help get Ian's work over the finish line.
