Connection to the target device is via UART interface. The user should configure the COM port number and the baud rate. Currently, no automatic detection of COM port is supported and the baud rate supported is 921,600 only.
The COM port number needs to be fetched from the 'Windows Device Manager'. Idially, all FTDI chipsets on the evaluation boards are pre-flashed. However, FTDI chipsets that are not flashed for some reason, can still be used as Uniflash requires a simple COM port.
Table 1 describes all possible permutations:
Evaluation Board | FTDI | #COM Ports | #COM Port for Flashing |
---|---|---|---|
CC3200 LaunchPad | Pre-flashed FTDI | 1 | The only COM port exposed |
CC3200 LaunchPad | Non flashed FTDI | 2 | The upper COM port |
CC3100 BoosterPack | Pre-flashed FTDI | 2 | The lower COM port |
CC3100 BoosterPack | Non flashed FTDI | 4 | The 3rd COM port |
In addition, the CC3200 LaunchPad can be made to work in two modes: functional mode and UART load mode.
UART load mode is to be used when flashing the device. This mode is selected by connecting "SOP2" jumper on J15 (denotes on PCB as '100:FLASH').
