question about tftp

william4015

Hi, everyone!

I encounter a problem when I set tftp,the variables I set in terminal console are follow:

SEED_DaVinci_EVM v1.0# setenv ethaddr 00:0c:29:e1:19:db
SEED_DaVinci_EVM v1.0# setenv ipaddr 192.168.0.107
SEED_DaVinci_EVM v1.0# setenv bootcmd 'tftp;bootm'
SEED_DaVinci_EVM v1.0# setenv bootargs mem=120M console=ttyS0,115200n8 root=/dev
/hda1 rw noinitrd ip=192.168.0.107
SEED_DaVinci_EVM v1.0# setenv serverip 192.168.0.105
SEED_DaVinci_EVM v1.0# setenv bootfile /tftpboot/uImage

The results of boot are follow:

SEED_DaVinci_EVM v1.0# boot
TFTP from server 192.168.0.105; our IP address is 192.168.0.107
Filename '/tftpboot/uImage'.
Load address: 0x2050000
Loading: T T T T T T T T T T T T T T T T T T T T
Retry count exceeded; starting again

How can I solve this problem?

I'm very appreciate for your suggestion! thanks

Are you using static IPs (by-passing or not using router)? Based on your bootargs setting "ip=192.168.0.107" it would appear this is the case; if so, please refer to the following App Note

If using dynamic IPs with router, please see Getting Started Guide.

Something I find curious is the bootfile equaling /tftpboot/uImage. If your tftp server is exporting the "/" directory as the base directory, then /tftpboot/uImage should work.

However, typically the tftp server is exporting /tftpboot already. In this case, the tftp client running on the target would see this as the base directory. I have used the following for the bootfile parameter:

setenv bootfile uImage
