Hi Angelo, Thank you so much for replying me.
Now, I get the file from u-boot site as you have directed. In our hardware flash is connected as 16-Bit Data Port means straight D0/D15 of flash to D0/D15 of CPU. No I haven't used TIMEOUT config field any way. I have tried erase command but cant run erase command. I will try it today proper. Second thing I have tried my custom code in cfi_flash.c file to write data in flash in write_buff(). So it works but it can not wite first 15-20 byte and then after it writes all bytes.

You can get the file fome there, just go to u-boot site, custodians, click "master", selct tree and click on the file. Still, some questions: How is the flash connected, as 8 or 16 bit data port ? Is the flash connected stirght D0/D15 to D0/D15 of the cpu ? Did you try to add the TIMEOUT config field, as i posted ? Can you try to use the command "erase" and dump to see if the flash can get erased ?
