Hi everybody,

I am using EDK 7.1 on WIN XP to port uclinux on Spartan 3 400 development board which has 8 MB SDRAM 4 MB flash.It has one 25 pin parallel port,one 9 pin serial port,an LCD along with other ports.Now my problem is that after executing "dow -data image.bin 0x20800000"

when I execute "con 0x20800000" nothing appears on TERA terminal.The address is the starting address of SDRAM as confirmed by .mhs file.Also after downloading the image file a memory read of that location reveals that contents of the location has changed.When I download a Test memory program The TERA terminal responds as test successful.Can anyone suggest a solution to me.I feel I have tried all the options.Using RS-232 cable also doesn't work at all.I generated the image file using the default option of "make menuconfig".Do I have to alter few options while compiling the uclinux which ive compiled on linux.

Thanking everybody in advance. Plz reply.

Regards

Kunal Kishore
