JM 02:55 PM PCB Development: RGMII PHY Electrical Specification

What is the electrical specication of the RGMII interface from the MityDSP? Is it 3.3 or 2.5V LVCMOS? Joel Meltzer

Just to let you know that if you set the phy register 9 (1000Base-T Control) to 0x0000 (turn off advertisement
for 1000 full/half duplex), then DHCP will work in uboot. I'm still looking into DHCP at gig settings.

Thanks Tim,
I've been beating my head against a wall for a bit so hopefully there will be something good
there.

02:26 PM Software Development: DHCP is erratic in uboot

We are having problem getting DHCP to work consistently on are board that uses the
the Mity AM3359 module (and our KSZ9021RL Phy). Port 0 failing is normal but when
port 1 finishes autoneg, I see the DHCP requests go out on the line an... Anonymous

So the simplest solution would be to build a "stock" image (minimal console image or something). That will at least get you a basic toolchain, bootable kernel and filesystem, and the open source software. Then you can add your own pack... Michael Williamson
