Device Diagnostics Harness

Objectives

  • Device harness firmware for post-assembly-line device quality assurance testing and RMAs
Existing Challenges

  • Buggy chipsets from China manufacturing
  • No automated control mechanisms from host
  • Custom FPGA design and integration details
  • Mixed chipset architectures. i.e. ARM, PIC, etc.
Solutions

  • C++ bespoke firmware for harness controller
  • Assembly code for functionality chipsets interfaces, i.e. wifi, bluetooth, hid’s, screen, usb I/O, etc.
  • Custom electric network integration
  • Windows .NET host controller application and utilities
Benefits

  • Dual-purpose harness for device testing during dev and mass production
  • In-house code for future feature and fix development
