Placing the Board in/out of Recovery Mode
Before flashing the board, use the AURIX console to put it into Force Recovery mode. Similarly, before resuming operation, use the AURIX console to remove the board from Force Recovery mode.
To place the board in Force Recovery mode
1. Follow the steps in Setting Up Your E3550 Platform to connect the USB A cable from the platform to the Ubuntu host.
2. Follow the steps in Powering On/Off the Device to power on the platform.
3. Start a terminal window on the host system, using Minicom or another terminal emulator, and connect to the AURIX port.
4. Verify Minicom configuration with the correct ttyUSB port for the platform.
For E3550, /dev/ttyUSB3 is the serial port for AURIX on the Ubuntu host system, assuming that no other USB serial adapter is connected.
For P3479, /dev/ttyUSB<number> is the serial port for AURIX on the Ubuntu host system, where a DB9-USB converter is connected to the DB9 “AURIX/MCU” connector on the harness.
5. At the AURIX console, enter these commands to put Xavier A (x1) and/or Xavier B (x2) into recovery mode.
tegrarecovery <device> on
tegrareset <device>
Where <device> is x1 and/or x2 for E3550, and x1 for P3479, and cvm for P2888.
