HI gvb
I was trying to print the status of phy registers by putting some debug statements in adjust_link function of tsec.c (drivers/tsec.c).
I found that after putting these debugs, i could not recreate the problem and ethernet works fine.
does this mean there is DDR2 initialization problem in my code..?

Hi,
In Ethernet PHY LAN8700 driver having some issues, during tftp the large file of more than 2MB of the binary file , some time its hangup & sometime its reset the board. same driver is working in evaluation board with same PHY & interface . if i tried in customize board the problem is occurring every 2- 3 of iteration. how to fix this issue..
Thanks Rudresh
Hi Rudresh,
If your ethernet driver uses DMA, it is probably due to a SDRAM (DDR/DDR2/DDR3) configuration issue (fixable) or a board layout issue (expensive to fix).
