This is not correct for your chip. You should have this set not less than the total number of ease units (blocks) on your chip.
For what I could find on the net this chip seems to have the following interesting geometry:
4 x 32kB 254 x 128kB 4 x 32kB
So, the total should be at least 4 + 254 + 4 = 262
Please fix this and provide the logs again...
Thanks Tolunay, I could fix the flash detection after changing the total no: of sector to 262. But the flash unprotect sector always times out.The first 4 sectors are protected when uboot comes up. I am not able to update uboot from within uboot since unprotect sectors always fails on these(all) sector. Should I need to change any timeout values.The log is as below.

I have another update. THe protect/unprotect failure was happening only when I was using h/w protect enable. I disabled h/w protect to see whether everything else goes well. But timeout happens on write as well. Below is the log message.

After disabling the buffered writes, write timeout doesn't happen. ALso protect/unprotect works well when h/w protect is enabled. Is there a way to use buffered writes on this flash device.
Thanks, Shiju
