Sample Projects

Here are some of the projects that we accomplished in the past.

Serial Bootloaders

  • Footprint that is small enough to fit into the OTP
  • Communication over RS-232, RS-422, RS-485 and TCP/IP
  • Servicing of external watchdog during entire reflashing process

CAN Bootloaders

  • Based on ISO 14229 (Unified Diagnostics Services)
  • Communication according to the ISO 157650-2 CAN Network Layer
  • Reflashing can be initiated via CAN command
  • Backdoor mechanism to recover from corrupt application code

Bootloaders with encrypted communication

  • Firmware is encrypted during compile process
  • Only encrypted hex files are distributed
  • Decryption occurs in target before flash is programmed
  • Flash CSM remains locked at all times

Concerto Dual-Core Loader

  • Supports reflashing of both cores in one session
  • Communication over USB Communications Device Class (CDC)
  • Custom image management and validation framework
