Dear "StephenPaulraj Chinnadurai-ERS,HCLTech",

- When the board is connected to network, through tftp the u-boot

Sounds like a instability of your hardware and/or U-Boot support for this board and/or platform.
- When the board is connected to Linux machine directly using
cross cable, through tftp the u-boot is downloading 47 MB size file without any retry, but when tried to download 53 MB size file, the u-boot is displaying "Retry count exceeded; starting again" message and download is not getting completed.
Are you aware of the restrictions of the TFTP protocol? In standard configuration, you can only load up to 32767 blocks of 512 bytes, i. e. not quite 16 MiB of data.
Most curent implementations treat the block number as unsigned, which shifts the limit to 32 MiB.
And if your TFTP server supports it you can also increase the block size.
Which exact settings are you using?
Best regards,
Wolfgang Denk
