[U-Boot] How do I use AM335x eth1 rather than eth0 ?
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 ?

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

Dear Bo Shen,

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.
