We have a dual Ethernet board (based on the BeagelBone) but with both Ethernet ports connected.
I'm wanting to use eth1 (rather than eth0), so in my board.c file, I changed:-
static struct cpsw_slave_data cpsw_slaves[] = {
{
.slave_reg_ofs = 0x208,
.sliver_reg_ofs = 0xd80,
.phy_id = 0,
},
{
.slave_reg_ofs = 0x308,
.sliver_reg_ofs = 0xdc0,
.phy_id = 1,
},
};
... to ...
static struct cpsw_slave_data cpsw_slaves[] = {
{
.slave_reg_ofs = 0x308,
.sliver_reg_ofs = 0xdc0,
.phy_id = 1,
},
{
.slave_reg_ofs = 0x208,
.sliver_reg_ofs = 0xd80,
.phy_id = 0,
},
};
... assuming that eth0 would now be ignored (as only 1 slave is configured).
But (eg) dhcp still only responds on eth0 !?!
What else do I have to change ?
Cheers

Have you try "setenv ethprime eth1"? Then reset board, and do dhcp.

Before thje reset, doi also a "saveenv" to make the setting stick.
Or "setenv ethact eth1" and retry then (without reset).

Thanks for you information, without reset is better.

Good question, do you have both ports working in Linux yet? The EVM-SK
design supports two interfaces and I know the cpsw driver in the kernel
required some changes to support two. I strongly suspect similar
changes would be required in the U-Boot driver (I don't have any
specific links other than look at the vendor kernel tree).

Well, I've realised I needed to change CONFIG_PHY_ADDR in my board
config file.
So the link up/down portion now works to PHY#2, but I'm still unable to
ping anything from our board.
I'm guessing there's some hard-coded assumptions in the cpsw.c driver.
I've taken quick look at the Ethernet section of the TRM, but that's
*waaaay* over my head !?!
I've so far been unable to get Linux to see the 2nd port, and there is
no "vendor kernel tree" ... I'm the vendor :-)
