Davinci-PSP-03.22: network related issue on boot

Hi all,

I’m working on a davinci custom board (AM1808).
I’m using Texas Instruments Davinci-PSP-SDK-03.22.00.06 that is based on linux-3.3.0.
Currently I’m facing with a problem with the kernel boot.
My boot options are

If I run the boot command with the Ethernet cable disconnected, the boot process has this strange behavior



…
davinci_mdio davinci_mdio.0: resetting idled controller
net eth0: attached PHY driver [SMSC LAN8710/LAN8720] (mii_bus:phy_addr=davinci_mdio-0:00, id=7c0f1)
(HERE IS A LONG WAITING PERIOD BEFORE CONTINUING….)
IP-Config: Complete:
device=eth0, addr=192.168.0.149, mask=255.255.255.0, gw=255.255.255.255,
host=192.168.0.149, domain=, nis-domain=(none),
bootserver=192.168.0.142, rootserver=192.168.0.142, rootpath=




Instead, if I run the boot command with Ethernet cable connected, the boot process is quite normal

I guess the problem could be related to davinci_emac.c, that is the reason I’m writing to you

Please can you help?

Best Regards

P.S.: I’m using the following boot options:
