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.

Thanks & Regards,
Ramesh

Dear Ramesh,

i am using last u-boot form git / master.

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 ?

Regards,
Angelo
