SMT376 User Manual
LED Setting
The SMT376 has 5 LEDs.
LED D6 always displays the state of the FPGA DONE pin. This LED is off when the
FPGA is configured (DONE=1) and on when it is not configured (DONE=0).
This LED should go on when the board is first powered up and go off when the FPGA
has been successfully programmed (this is the standard operation of the boot code
resident in the flash memory device). If the LED does not light at power-on, check
that you have the mounting pillars and screws fitted properly. If it stays on, the DSP
is not booting correctly, or is set to boot in a non-standard way.
Four of the remaining LEDs can be controlled with the LED register. Writing 1 will
illuminate the LED; writing 0 will turn it off.

Code Composer
This module is fully compatible with the Code Composer Studio debug and
development environment. This extends to both the software and JTAG debugging
hardware. The driver to with the SMT376 use is tixds6x1x.dvr. Code composer V2.2
is required for the SMT6001 to work.
