u-boot dhcp command hangs

Other Parts Discussed in Thread: OMAPL138

I set up my DM8148 EVM (without the expansion board and LCD display) and flashed u-boot in NAND. When I try to run dhcp from u-boot it just hangs. The network is working ok because I can use the same ethernet cable attached to an OMAPL138 EVM and it runs dhcp in u-boot successfully. What is happening on the DM8148 is shown below:

...

Net: Detected MACID:40:5f:c2:6:a3:17

cpsw
Hit any key to stop autoboot: 0
TI8148_EVM#printenv

ethaddr=40:5f:c2:06:a3:17
ethact=cpsw
...
autoload=no
...

Environment size: 970/8188 bytes
TI8148_EVM# dhcp

Do you have any idea what may be causing this?

I found that I was using a newer version of the CodeSourcery toolchain to build u-boot. When I use the recommended toolchain, and then try dhcp in u-boot it is now reporting "Auto negotiation failed".

How can I fix this?

Can you provide the below details for further analysis.

PSP version
EVM revision
On which port Ethernet cable is connected (J14 or J27)

with regards

The PSP version is EZDSK 5.03

The EVM version DDR3 PG2.0 Rev C

The ethernet cable is attached to J27

Its kind of strange. I decided to upload the Linux kernel to the EVM, flash it to NAND, and change the u-boot environment to boot from that kernel rather than tftp'ing the kernel. When I did that Linux boots up fine, establishes the IP connection, and connects to the filesystem via NFS with no problem. It seems just to be a problem with the u-boot dhcp command.

uboot supports only EMAC 0 which is populated at J14 on EVM, please connect the cable to J14 and try out.

Kernel supports both EMACs.
