HP41 TULIP4041 update

[foldedtoad]

Just to let people know, I have resolved the "unaligned fault" problem I posted prior.

The following is for those interested in building TULIP on a Linux system; Ubuntu in particular.

In communicating with ThomasF, he indicated that his Ubuntu system was building w/o issues. (Thanks again, Thomas!)
This pointed to something in my build environment was amiss.

So I decided to completely reinstall the pico-sdk.
This install (Version 2.1.0 is now latest) went without any problems.
But when I tried to actually build TULIP, i received an error message indicating that picotool version was not at the 2.1.0 level.
By running the CLI command below, you can get the version of the picotool in your ${PATH}.

$ picotool version -s

In my case this indicated a picotool version of 2.0.0.
So I downloaded (from github), built and installed the latest version of picotool.
Now the "picotool version -s" command showed 2.1.0.

A minor change was made to ./TULIP-DevBoard/TULIP4041-P2/CMakeList.txt to bump the pico-sdk version number to 2.1.0.
With these changes, my TULIP build environment (on Ubuntu 22.04) is working per normal...no unaligned-fault issues and all CDC instances work as expected.

I am still not 100% clear as to how picotool influenced the "unaligned" issue.
From a cursory looking at the picotool code, I see that it contains a number of post-link functions.
So, my guess is that somehow the attributes(align) declarations were different or ???

Hope this info helps anyone else with a similar situation.
