Hi nbegley, everything is still right there in git, on the v1_0 branch. It should work fine if you simply check out that branch of freedom-e-sdk
I just tried it, from scratch:
git clone --recursive -b v1_0 https://github.com/sifive/freedom-e-sdk.git
cd freedom-e-sdk
make tools
curl https://static.dev.sifive.com/dev-tools/flash_bootloader.sh | sh
No problems. In particular the patching still goes fine:
$ patch -p1 <$TPATCH
patching file Makefile
Hunk #2 succeeded at 189 with fuzz 2.
patching file bsp/env/freedom-e300-hifive1/flash.lds
Building double_tap_dontboot works fine.
