DRA750: DRA750 OMAP CPU

Hi,

Edi Fraiman said:

Is it 3 ports switch? Two ports external and one internal inside CPU?

Yes, It is same as 3-port switch with two external ports and one internal CPPI port. 

Edi Fraiman said:

If so, is it any performance degradation from two external gig ports to only one internal?

No, Internal port is capable of handling traffic from both external ports.

Hello,

Thank for prompt reply.

Does the i880: Ethernet RGMII2 Limited to 10/100 Mbps  resolved for Silicon revision 2 and rev02 can support RGMIII 1000M?

If so, how to identify that chip is rev02 silicon?

Regards

1.Any visual mark on the chip package that specifies silicon revision?

2. Does any limitation how many SERDES/Interfaces I cam use (any muxing)? Can not find any documentation about that or maybe application that helps to choose right pinout for specific interfaces?

I am planning to use following interfaces:

GMAC0, GMAC1 (both GIG)

PRU1, PRU2 (MII 10/100M)

UART for RS232

USB2

3 x I2C

MMC1 for microSD

MMC2 for EMMC

EMIF1 for DDR3

GPIOs

Sorry I confused...

Reading "DRA75x, DRA74x Infotainment Applications Processor
Silicon Revision 2.0" and can not find information about PRUs. What DRA750  CPU pins dedicated for PRU0 and PRU1

what is PRU interface name in Sysconfig tool?
