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.
Try disabling debug outputs in CFI driver. I've seen writes do fail when debug output is enabled.
I tested disabling the debug outputs. Still writes and protect/unprotect fails if CFG_FLASH_USE_BUFFER_WRITE is defined.
Thanks, Shiju
