Build instructions don't mention building bba #56

Closed vmedea closed 3 years ago

vmedea commented 4 years ago

The build instructions in the README don't mention building the bba file. I guess it was recently split up? I noticed that the script build_bba.sh needs to be run first, to generate the file ecp5-bba-linux_x86_64-nightly.tar.gz, otherwise build.sh fails on a tar command in the compile_nextpnr_ecp5 step. (there also appears to need to be a clean.sh step in between build_bba.sh and build.sh otherwise it gets confused about the pre-existing git checkout, but if you're not careful to first copy the generated file out, you'll end up losing it :innocent: )

Yes, fair point, I got nextpnr working early on and since then haven't been running full builds locally. So as you point out, it's very clunky to run the whole lot locally.

I will try to get around to making the bba thing smoother locally and write some up-to-date dev instructions (the ones in the readme are mostly just inherited from fomu-toolchain) so that I don't scare away any other potential contributors :P
