How to use the Linux Updater
The update procedure can be divided into the following steps:
1. Connect the TC1 via RS232 to the host PC from that the update has to be executed
2. Execute the start script tc1_updater_for_linux
3. Follow the instructions on the screen
(For some steps during the update process super user permissions are mandatory. Therefore, the updater
will ask for the sudo password.)
How to test the RS232 connection
1. Open a terminal program on the host PC (for example Hyperterm, or the TeraTerm that is supplied in the
tterm folder)
2. Setup the serial port where the device is connected to the following settings:
a. 115200 baud
b. 1 stop bit
c. no parity bit
d. no handshake.
3. Switch on the power supply of the TC1 controller.
You should see the boot messages of the U-Boot and Linux kernel in the terminal.
