Subject: question: Why the nand_wait() wait for 20ms for nand program.
Date: Fri, 18 Jan 2013 16:05:17 +0800	[thread overview]
Message-ID: <50F9023D.5040408@freescale.com> (raw)

Hi all:
Why the nand_wait() wait for 20ms for nand program. could we
expand this time to 40ms? I have a nand chip : Micron MT29F64G08CBABAWP.
The chip's BUSY/READY pin may needs more then 20ms to become ready,
though its
datasheet tells me the tPROG's max value is 2.5ms.

thanks
Huang Shijie
