Userspace Arduino:To Do
A to do list of all the things for Userspace Arduino project started in GSoC '13
- GNU Netcat networking tool http://netcat.sourceforge.net/
- Can create a connection using nc -w 1 192.168.7.2 1114 < new.zip on the server (in this case the machine running the Energia IDE), and nc -lp 1114 > n.zip on the Beaglebone. 1114 is a random port number which has to be the same on client as well as server side.
- Some issue with sending .bin files directly. Mostly it was with how the file ends, not sure. So need to zip the file.
- Requires no authentication
- A script will be needed to listen on a particular port on the BBB for any incoming connections which will receive, unzip and execute the code.
- Needs ssh and sftp installed
- Need to configure keys initially. Works without user authentication after that
- Code to upload and execute binary here : https://github.com/anujdeshpande/send_exec
Emulating the Arduino bootloader
- The Arduino Bootloader uses a protocol similar to STK500v1 (over UART, though)
- One way to program (copy) the binaries would be to emulate the protocol on the bone over USB gadget and use AVRDude on the IDE side
- However this would be cumbersome, since the protocol was designed to write bytes to flash memory, not copy files.
- Energia uses mspdebug to flash the MSP430 using a serialized version of JTAG called Spy-Bi-Wire (SBW).
- File transfer protocols over serial like XMODEM and ZMODEM could be explored for an easier and more compatible option to Upload the binaries.
- Install the lrzsz package on both the host (PC) and the client (Beaglebone):
apt-get install lrzsz
- Connect the Beaglebone via USB and determine the port (for e.g. /dev/ttyUSB1). Once the OS is booted up, start the transfer:
sz -vv -b filename.bin < /dev/ttyUSB1 > /dev/ttyUSB1
- Send executable over port 80
- On BBB, listen for any uploads and execute them
