Connection between TMS320C6670 and USRP

Muhammad,

What is USRP N210?  How does it connect to C6670?  C6670 does not have an USB interface.

Hi Tom ,
Thank for your response ,
USRP is an Ettus board which have FPGA and daughter board and i want to use it as my front end to transmit data ,
i want to connect between them using the Ethernet cable

Muhammed,

The C6670 EVM has an Ethernet port that supports Gigabit Ethernet.  You can connect this directly to your FPGA board assuming it also has an Ethernet PHY with autonegotiation enabled.  You could also connect them through a switch.

The Quick Start Guide for the EVM shows you the steps to run a demo over Ethernet.  You should execute those steps to learn how to connect and use the Ethernet port.

Hi Tom ,
Thanks for your reply ,
I have another question ,
I want to get digital bits from DSP using GPIO pins ,
My question is how i configure the registers of GPIO to do this using C code on CCS which connected with TMS320C6670 board cross XDS560 JTAG ??

Thanks in advanced ,
Muhammad .

Muhammad,

The User Guides for the various peripherals are on the TI.COM product page.  For C6670, this is: http://www.ti.com/product/tms320c6670.  You need to click on the link for the "General-Purpose Input/Output (GPIO) forKeyStone Devices User's Guide".

Hi Tom,
Thanks for your reply ,
I am already read the GPIO guide and i understood for example if i want to configure any pin of the GPIO as input , it is required to access the DIR register and write 1 to the corresponding pin ,
the question here how i do this using the c code which implemented on CCS project and target the board cross XDS560 emulator ???

Thanks in advanced,
Muhammad.

Muhammad,

I recommend that you take some CCS and MCSDK training.

Tom

Hi Tom ,
Thanks for your fast reply ,
Already i do this and  i succeeded to run "Hello world example"  and other programs on the DSP using CCS and the connection between them was XDS560 ,but i don't know how to access the GPIO registers  ?

Thanks in advanced,
Muhammad .
 

Muhammad,

The address map is found in the C6670 Data Manual.  The MCSDK has code examples.

Hi Tom ,
Thanks for your help ,
i want for your help again ,
when i want to call  function to initialize GPIO  i am called this function using the this simple program :
#include <evmc66x_gpio.h>
void main()
{
gpioInit();
}
evmc66x_gpio.h it is located at this directory 
C:\Program Files\Texas Instruments\pdk_C6670_1_0_0_17\packages\ti\platform\evmc6670l\platform_lib\include
but when i built the project it appears an error which is that
 C:\ProgramFiles\TexasInstruments\pdk_C6670_1_0_0_17\packages\ti\platform\evmc6670l\platform_lib\include\evmc66x_gpio.h", line 108: error: identifier "uint32_t" is undefined

Can you help me please ?
Thanks in advanced ,
Muhammad .
