Topic: 8MB MX flash chip problems?

The content of this topic has been archived on 15 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

So this little 8MB chip from MX (MX29LV640) is becoming quite popular. I have a few devices which use this flash chip.


On any of these devices, doing:

mtd -r erase rootfs_data

Successfully clears the partition, but hell ensues after the reboot.

SQUASHFS error: Unable to read page, block 1106cc, size 347c
SQUASHFS error: sb_bread failed reading block 0x44e
SQUASHFS error: Unable to read fragment cache block [1106cc]
SQUASHFS error: Unable to read page, block 1106cc, size 347c
SQUASHFS error: sb_bread failed reading block 0x257
SQUASHFS error: Unable to read fragment cache block [92013]
SQUASHFS error: Unable to read page, block 92013, size 3e7f

On and on and on and on...


The device must be rebooted once more, or sometimes twice more, until everything is clean and mounted properly.


Since I'm experiencing this on multiple platforms with this same chip, I'd assume other people have this problem as well? Wondering how to start tackling this issue.

Hi aport:
Now, i am working on the MX29LV640 8M flash project with SQUSHFS file system.

I got the same issue.

Had you found out the reason about this issue?

Or if you have any solution, could you please shared it?

thanks.

The discussion might have continued from here.
