8.1 Getting Started
The UART Boot Host utility is installed alongside the AISgen utility. For installation instructions, see Section 5.2. After installing AISgen, look for the UART Boot Host in the UartHost subfolder. Run UartHost.exe to begin.
The UART Boot Host utility consists of a single window. This window handles all configuration, allows you to start and stop the boot process, and reports status and error messages as the device boots (see Figure 25).
Figure 25. UART Boot Host utility The AIS File text box specifies the AIS file to be used during boot. Note that only binary AIS files should be used; AIS files in C header format are invalid. The file can be typed manually or found using the browse button (“…”).
The Serial Port text box specifies the name of the serial port that will be used to boot the device. For most PCs, the serial port has a name like COM1 or COM2. The default baud rate used by the bootloader is 115.2 kbps. For more information on using different baud rates, see Section 9.
The Wait for BOOTME checkbox allows you to specify whether the PC waits to receive BOOTME on its serial port before beginning boot. This should be checked by default.
The large read-only text box displays status and error message during the boot process. It will initially be blank and should automatically clear itself at the beginning of each boot process.
The Start and Stop buttons, respectively, initiate and abort the boot process. The Start button is only active when no boot is currently in progress and the Stop button is only active when boot is currently in progress.
