Fixing a uname bug (Apache NuttX RTOS)

Watch as we stomp the seemingly simple bug… That turns out to be something seriously sinister! (Spoiler: Static Vars are broken)

That Header File was created at build time from a Hidden File that you can find in the top-level nuttx directory called .version.

And that’s our CONFIG_VERSION_BUILD with Commit Hash! Looks hunky dory, why wasn’t it returned correctly to uname and NuttX Shell?

Now we chase the uname raving rabbid inside our NuttX App. Normally we’d dump the RISC-V Disassembly for our Hello App ELF…

After That: Since we can Rewind NuttX Builds and automatically Git Bisect… Can we create a Bot that will fetch the Failed Builds from NuttX Dashboard, identify the Breaking PR, and escalate to the right folks?
