Subject: nand flash driver problem
Date: Tue, 13 Jan 2004 11:30:16 +0800 [thread overview]
Message-ID: <002201c3d985$8ff790f0$1a140a0a@leonnb> (raw)
Hi all,
I am using JFFS2+MTD nand driver(uClinux Full Source
Distribution 20030909) to mount Samsung 16MB Nand flash. It looks ok except
writing time(It costs about 40seconds for copying a 200KB file to Nand
flash). Even I patch uClinux by New JFFS2+MTD nand
driver(mtd-snapshot-20031217) , I still get the same result. But I measure
the actually time that Nand flash erasing and writing one page is no more
than 1ms.
I also do another test for reading or writing Nand flash by MTD
block driver and it is ok (I mean reading or writing 200KB data from/to Nand
flash is not more than 1 second). So I don't know what the problem is. Do
anyone meet the similar problem or any idea?
Thanks
Lys
