Protocol Stack

ECE 4007L01 - Dr. Whit Smith


Project status

  • Communication with SBC

    • Issues setting up USB drivers

  • Ran C code on SBC

    • Set up Linux environment

    • Crosstool for TS-7250

  • Established API concept

Project Status

ECE 4007L01 - Dr. Whit Smith


Acceptance testing

Acceptance Testing

  • Confirmation of SBC functionality

    • Transfer files via HyperTerminal

    • Executed simple C programs on SBC

  • Confirmation of USB-to-GPIO recognition

    • Confirmed USB recognition on the SBC, yet no native driver can be assigned for communication
