What did you do?

following instructions of README.md mostly:

1. cd into src and build golang toolkit
2. cd into biscuit, adjusted GOPATH, QOPTS and run make qemu CPUS=2

Here's detailed modifications:

For me, the following solution worked:
In biscuit/src/kernel/syscall.go:3314 change 512 to 1024 (or some number larger than 512). It seems that the new init executable generated is larger than 512 bytes, but the value is hardcoded in this line.
After this change, I ran make qemu CPUS=2 again and I was dropped in their shell
