User debug led registers. TMDSEVM6670L board

Good day to you again. 

There's some unknown things about user debug leds on the scheme. I've searched the PDK documentation, but i didn't find information about leds register description. I need assembly or C code, for more information on how to connect to the leds, with the addresses of the requested registers. This is very important because I want to know how the processor communicates with the FPGA, and that, in turn, registers. It would be great to see the algorithmic structure if it is. If it is missing, please give a link to the program files.

With best regards, Taras.

    Hi,

    User Debug LED's are connected to FPGA. DSP(TMDSEVM6670L) will control the user LED's via SPI interface. MCSDK led_play example use this debug LED's. Refer MCSDK user guide for this LED driver code:

    For more information refer platform device driver code(platform.c and evmc66x_fpga.c) and C6670 technical reference manual:

    MCSDK Path: C:\ti\pdk_C6670_1_1_2_6\packages\ti\platform\evmc6670l\platform_lib\src\

    Thanks,
