[U-Boot] TFTP timeout issue while downloading the linux kernel in openpxa vpac270 u-boot source code

[StephenPaulraj Chinnadurai-ERS,HCLTech]

Hello Marek,

I am using a customize board which has PXA270 controller.  SMCS LAN91C111Ii-NU is connected to the static memory 4 (nCS4).

I have defined following macro value in the include/configs/<myboard.h> file.

#define CONFIG_SYS_GPDR2_VAL    0x70DF3FFF
GPIO 80 is configured as output

#define CONFIG_SYS_GPSR2_VAL    0x10010000 /*nCS4*/
GPIO 80 is set

#define CONFIG_SYS_GAFR2_U_VAL  0x1504A176
Alternate function 2 is selected for GPIO 80

#define CONFIG_SYS_MSC2_VAL     0x0000B884

RT4 = 4  Variable Latency I/O (VLIO)

ROM4 Bus Width
0 = 32 Bits

RDF4 = 8

RDN4 = 8

RRR4 = 3

RBUFF4 = 1 Faster device

#define CONFIG_SMC91111
#define CONFIG_SMC91111_BASE    0x10000300 /*nCS4*/
#define CONFIG_SMC_USE_32_BIT
#undef  CONFIG_SMC_91111_EXT_PHY


Ethernet controller is working fine. I can able to ping the machines connected to the network.

tftpboot command is also working fine, I can able to download the u-boot.bin to SDRAM.

But I have issue in downloading bigger files (zImage which is 2.5 MB) to the SDRAM. I am getting the following timeout messages and the download is not getting completed.
