P1010/LS1021 lane 复用问题

[bratzhang]

您好！

     请问QorQ系列的P1010能否同时支持3个千兆以太网，1个PCIE， 1个SATA同时使用？还有，serdes使用的复用关系是怎么样的？

     盼复，多谢。

Hi Sir:

     My question is ,do  the P1010 or LS1021 run the GMAC*3 and PCIe/SATA at the same time ? How about the vedio serdes to use in hardware?

    Thanks !

> GMAC

SGMII or RGMII?

> PCIe/SATA

PCIe or SATA?

> vedio serdes

Sorry, what do you mean?

[bratzhang]

3*SGMII+PCIe+SATA , I see that the p1010 just has 6 lane to share with peripheral to run , can they work together?

If so , how can the serdes reused in such domain?

[ufedor · Accepted solution]

Yes.

The P1010 SerDes could be configured as PCIe + 3xSGMII + 2xSATA (cfg_io_ports[0:1]=0b10).

Please refer to the P1010 QorIQ Integrated Processor Reference Manual, Table 4-14. SerDes I/O port and protocol selection.

> If so , how can the serdes reused in such domain?

The question is not clear - please elaborate.
