Tessel 2 is seeking FCC approval. Tessel 2 runs OpenWRT, a distribution of Linux designed as open firmware for routers with very granular control over wireless capabilities. Currently Tessel 2 is stuck in FCC approval pending its demonstration of being able to generate packets in the 802.11n range.

Testing instructions

Installation on a Tessel 2:

opkg update
opkg install tcpdump
wget https://kevinmehall.net/tmp/packetspammer -O /usr/bin/packetspammer

tcr

Setup

1. Install OpenOCD. You need version >= 0.8.0.

• This version is not in Ubuntu 14.04, but the packages from Ubuntu Utopic work fine there
• brew install open-ocd installs >= 0.8.0.

1. Acquire a configuration script for your Bus Blaster. Included in the firmware repo is tools/tessel-busblaster.cfg.

2. Plug the JTAG cable into the Bus Blaster's adapter board and the Tessel. Pin one is towards the USB port; the cable goes over the center of the board.

3. Run

tcr

#!/usr/bin/env ruby
 
# checkout the readme from the master branch
`git checkout gh-pages; git checkout master README.md`
 
path = `pwd`.gsub(/\n/, "")
readme_path = File.join(path, "README.md")
index_path = File.join(path, "index.md")
 
# write the index readme file
