Message: 68044

Hi.

I have a "BF527 Ez-kit Lite" and uClinux-dist-2008R1.5-RC3.

I try to use NAND FLASH with YAFFS or JFFS2 file system.

If I try copy any file to the partition don't works. The linux prompt freeze.

If I reboot my board and try mount partition don't works too. Thats necessary erase the partition every time?

How can I work with NAND and file system?

Thanks and Regards, Samuel.

have you set the switches properly to disconnect the ethernet and hook up the nand ?

Hello Mike.

Yes, I was set the switches to disable ethernet and hoop up the nand.

If I run "nand info", I have:

Hi Samuel,

do you solved your problem ? I'm currently working on nand flash device on my board and i'm interested in your case. it seems that i have some problem too.

Hi Stephane.

Still I can't solve my problem.

I achieve mount filesystem with yaffs2. But write operation don't work, the linux prompt freeze.

I don't have idea.

Regards, Samuel.

hi samuel,

it seems that i have the same thing. detection is ok (i've got a micron nand flash), mount seems to be ok ; it detects the bad blocks. there is one lost+found directory and thats all.

when i try to create a directory or a file, or even if i try to umount the nand, the console freeze...

no idea for the moment too...

what option did you include in the kernel ?

ps : could you just try one little thing for me : as you have the ezkit, could you disconnectt the nand flash and try to boot ? in my case, when there is no nand flash chip and when nand flash support is added to the kernel, the kernel crash at bootime.

regards

Stephane

Hi Stephane.

I made the test that you ask me.

My kernel is compiled with support to NAND.

----------------------------------------------------------------------------------------------------

Device Drivers --->

Memory Technology Device (MTD) support --->

NAND Device Support --->

<*> Blackfin on-chip NAND Flash Controller driver

[*] BF5XX NAND Hardware ECC

[ ] Use Blackfin BootROM ECC Layout

----------------------------------------------------------------------------------------------------

I disable the NAND in my ezkit and receive a kernel panic too.

"Kernel panic - not syncing: Kernel exception"

Hi Samuel and Stephane,

I can reproduce this issue on my BF527-Ezkit, using the svn trunk kernel. The "cp" (busybox) process would hang there when r/w the Nand flash. I've also commit a bug to track it at: https://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=4833.

Hello Yi,

I am responsable for Samuel Coelho. Our Team would like to know if it is possible to change the priority of this "bug" from Medium Priority to High Priority ?

We are up against the clock. We have a critical deadline to meet, and can not do it as long as this bug is in place.
