I am having a problem in uboot with eth_initialize() function on my target. My target is based on Intel Arria10. All the uboot source code, that I have seen, seem to assume that there is a PHY device attached to the cpu emac0. On my target I do not have a PHY attached to the emac0, but there is a direct connection to a Marvell 88E6321 at port 5 which is RGMII. So I have RGMII to RGMII from Marvell switch to cpu arria10 emac0 .
When u-boot code in common/board_r.c calls :
static int initr_net(void)
{
puts("Net: ");
eth_initialize();
I get : Could not get PHY for ethernet@ff800000: addr -1
and then "No Ethernet found"
I am trying to figure out what changes I need to make to current uboot to make it work. How do I tell you uboot that there is an ethernet switch connected and not a phy . Any hints would be appreciated.
Does you have any uboot source code that use such implementation?
Thanks Claudio
