Hello,
I am new to the U-Boot. Currently I am porting a the U-Boot 2008.10 to our customized MPC8548 board. I can boot up the board with the U-Boot now. And if I use the direct connection to the host computer, there is no problem to tftp or bootp file from the host.
In order to keep the host connection during the target reboot. I made the connection through a Gigabyte Ethernet switch. And the target can not reach the host through the switch. I tried to Debug this problem by define the ET_DEBUG to printout some information. And also add some extra printf statement in the tftpsend function in the tftp.c file. after that I can tftp file from my tftpboot. I can not really finish the file transfer because of tons of information comeout from the console and slow down the process.
Does any one have any idea about what happened in my case? Thanks alot!
