Is there a PHY attached to VSC7385 on P1020RDB?

[bilalwasim]

I've been working with P1020RDB for sometime now. For the eTSEC1 device, there's VSC7385 switch attached to it. As far as I can get, there should be a PHY attached to the switch. However, I'm never ever getting link status UP. Can someone clarify if there's a PHY attached to VSC7385?

Thanks,

Your assumption is not correct.

The VSC7385 is a 5-port Integrated Gigabit Ethernet Switch SoC with integrated Copper PHYs.

Ya, there's a PHY attached to the interface, but I'm currently unable to get it to work. What I want to do is that the PHY polls the link status register to check whether or not the link is UP, but the link status register doesn't seem to respond. It seems to remain UP (or DOWN) by default, and doesn't change status when I connect/disconnect the wire. Could be a problem with the BSP I'm using. Other possibility is the hardware limitation. But I haven't been able to find any evidence of that anywhere.

Which BSP is used?

Is the VSC7385 microcode loaded?

[bilalwasim]

Well its proprietary BSP, and I can't comment on that. I don't understand what you mean by VSC7385 microcode? I'm just a beginner and oblivious to most of the jargon.

Normal operation of the VSC7385 is impossible without externally loaded microcode.

Please download NXP/Freescale Linux SDK 1.9 for e500v2 core to make yourself familiar with this.
