TMS320C6678: 2 SRIO ports (Each SRIO port to communicate with Zynq and k7 FPGA) and 1 Ethernet port in a C6678 DSP.

Hi Noufal,

I've forwarded this to the SRIO experts. Their feedback should be posted here but could you specify what software running on your board?

Hi Tsvetolin Shulev,

RTOS application generated using CCSv5.

Hi Noufal,

SRIO driver examples are provided in PDK of Processor SDK RTOS, processors.wiki.ti.com/.../Processor_SDK_RTOS_SRIO

You can download the latest Processor SDK at software-dl.ti.com/.../index_FDS.html, (CCSv6.1.3 is required)

SRIO user guide is here: www.ti.com/.../sprugw1, and the SRIO LLD design document is in pdk_c667x_2_0_x\packages\ti\drv\srio\docs\SRIO_SDS.pdf.

Look into SrioDevice_init() function for SRIO port configurations.

Hi Garrett,

i have two SRIO connection to different FPGA and one Ethernet to host PC. for SRIO case, Should i use separate memory region or same can be used for both SRIO communication?

Hi Noufal,

You can refer to the dioSocketsWithISR() function in loopbackDioIsr.c of SRIO_LpbkDioIsr_evmc6678_C66BiosExampleProject to check how to allocate different memory (buffers) for SRIO sockets.

Garrett

Hi Garrett,

i searched my installation folder. under mentioned there is no loopbackDioIsr.c file.

i need one more help from members..

i would like to know about SRIO enumeration between DSP, ZYNQ and K7 Fpgas where all are on the same board.

Noufal,

Are you using the pdk_c667x_2_0_4 from latest Processor SDK 3.2? see

\ti\pdk_c667x_2_0_4\packages\ti\drv\srio\example\SRIOLoopbackDioIsr\src\loopbackDioIsr.c

Garrett

Nope,

am using pdk_C6678_1_1_2_5. i got the file. but there is no dioSocketsWithISR() function.
