hi, all

 

the nand flash on my board is st nand512w3a, I used yaffs2 file system.

 

When I used uClinux-dist-2006R2-RC2, there is anything err, but when I use uClinux-dist-2008R1-RC8, when I access the nand flash the err is:

 

yaffs: Block struck out

**>> Block 290 retired

yaffs: Block struck out

**>> Block 292 retired

yaffs: Block struck out

**>> Block 289 retired

yaffs: Block struck out

**>> Block 293 retired

 

I didn't change anything about mtd and yaffs2 source file under the uClinux-dist tarball, so i think there are some bugs in uClinux-dist-2008R1-RC8.

 

Can you give me some suggestions?

 

thank you!

thank you

 

I did it, but the same err.

 

after I  erased the flash, all the bad blocks can be used, but the same err occured again when I accessed the flash.

I think it's a bug about uClinux-dist-2008R1-RC8, all the options about yaffs2 and nand are the same as 2006R2-RC2, and I didn't modiy any source file about yaffs2 and nand flash.

Could you list the detail steps to reproduce this bug? Or could you just report a bug?

I'm successed to use an NAND-FLASH in 08R1-RC8 released. Make sure your protection and reset gpio is correct and select the correct chip_select for EBIU_AMGCTL

ww:

 

We list all the things we test before a release is made at:

 

https://docs.blackfin.uclinux.org/doku.php?id=uclinux_release_check_list

 

Since NAND is on there (although it is most likely yaffs2, not yaffs) - we tested it before the release was made.
