When I booting the EVM with u-boot>dhcp, the loading exceeds the maximum time set. Message as: "Retry count exceed. starting again. " I checked the TFTP status. It's running. But when I tried to download uImage with command: "tftp 192.168.0.1 get image.bin" on another computer, message came up as "transfer time out".

What's the problem?

Ketty,

does u-boot support DHCP? I never tried that. Instead I configure the Ethernet interface for a fixed IP, set MAC address and gateway through environment variables. Once ping (from u-boot to host) works you should be able to tftp your files.

The kernel then might be started with DHCP options. That is independent.

Regards.

Hi,

The below link seems to indicate the support for DHCP in u-boot and instructions for using the same -

Please check if this helps.

Thanks,

Prathap.

Prathap, thanks!

There is always something to learn. Indeed this worked for me:

AM3517_EVM # dhcp 80000000 192.168.1.3:uImage
BOOTP broadcast 1
DHCP client bound to address 192.168.1.2
Using DaVinci EMAC device
TFTP from server 192.168.1.3; our IP address is 192.168.1.2
Filename 'uImage'.
Load address: 0x80000000
Loading: ###########...

Regards.

Did you use RPC to setup a tftp server? I use redhat linux x86_64, and I downloaded tftp-server-0.49-6-6.fc14.x86_64 and could not install it with "libc.so.6 is needed y package.."

We do have to assume you have a working TFTP server on your host. We can't support host configuration issues as there are too many variations of that. In my case I use an old Ubuntu image for a long time and the TFTP server was working from the beginning (never change a running system...).

You might want to ask your IT department or the Linux community for help.

Regards.

About step 3: Copy the file system image from the /tftpboot directory of your Linux host workstation.

host$ cp <path to ramdisk file> /tftpboot

Can not understand this step. Where is ramdisk file? And this seems not to "Copy the file system image from the /tftpboot directory of your Linux host workstation"
