5.2 Test Description

  • This uses direct access mode on F28002x side. The Host sends the data over FSI TX and reads the data from FSI RX.
  • The Device side sets up the HIC, configures one region for FSI Base address and sends one token D2H to Host after the FSI module is configured in Loopback mode.
  • The Host programs the FSI TX Buffer through direct access mode and starts the transmission
  • The Received FSI RX interrupt is directly notified to Host via HIC Event Trigger Bus through HIC_INT.
  • On the reception HIC_INT the Host reads the FSI RX Buffer through direct access mode.
