6.1.2 Hardware

After building the kernels in CCS, setting up the device correctly to be able to communicate with the host PC running the serial_flash_programmer is important. The first thing to do is make sure the boot mode select pins are configured properly to boot the device to SCI boot mode. Next, connect the appropriate SCI boot loader GPIO pins to the Rx and Tx pins that are connected to the host PC COM port. A transceiver is often needed to convert a Virtual COM port from the PC to GPIO pins that can connect to the device. On some systems, like the controlCARD, an FTDI chip is used to interface the GPIO pins used for SCI communication to a USB Virtual COM port. Refer to the user guide for the controlCARD to get information on the switch configuration needed to enable SCI communication. In this case, the PC must connect to the mini-USB on the controlCARD and use channel B of the FTDI chip to connect to the GPIO pins on the device. After the hardware is setup correctly to communicate with the host, reset the device. This boots the device to SCI boot mode.
