Re: CoinTerra announces its first ASIC - Hash-Rate greater than 500 GH/s
That's about the least helpful reply you could give to what I presume is your answer to this question:
anyone know who to update cgminier , is this done via SSH? the stock version is 3.12.0 and well 4.0 is out and 4.0.1 is on its way
The answer is: it's not easy. Cointerra has some kind of minimalistic linux build running in a small 32MB partition. They have a full Angstrom build mounted at /Angstrom but you can't run any binaries from there (the dynamic linker seems to not want to run them). The cgminer binary that's running in all stock Cointerra boxes right now was custom build against uClibc, a minimalistic libc for embedded systems. If you want to build your own version of cgminer, you must either cross compile your own armv7 binary that links against the installed libraries in the beaglebone (in /lib), or get the full Angstrom distro somehow running and install a build environment with opkg.
KNC runs identical hardware, but you can actually run opkg right from the command line and get git, gcc, etc. installed without changing anything. On cointerra's build, not so.
tl;dr; it's not easy, and I'm curious myself.
