Tiny6410 (2GB NAND flash MLC) lost os

hic
Hi all,

I have Tiny6410 board. I installed Linux Embedded and develop some
application in this board but i have big issue about this board. That is if
i dont using that board in long time (about 1 week or 2 weeks) and when i
want to continue start that board then the board can not boot in to OS and
if i want to use it I need re-install OS. What is happen with my board??

It would help to have a terminal program running on your host, a serial
cable connected to the target and observe the bootup messages ... when you
fire the board up.

What media is the kernel and rootfs on?  SD card?

Thanks davef,

I installed OS on the flash in this board by SD Card and I tried install OS
by USB cables by this issue is continues. OS is Linux on DVD of this board.

I have two boards tiny6410. One is Tiny6410 with SLC flash (256MB) and one
is TIny6410 with MLC Flash (2GB) and this issue only happens with board has
MLC flash.

You have to look through your boot messages to determine the problem.

Hi Davef,

I'm very sorry because I do not save this log. 

But when i start this board and connect COM0 to monitor then I see that
this board repeat log is:

MAC: 08:90:90:90:90:90                                                     

    
Hit any key to stop autoboot:  0

If i press any key then bootloader will start and i can't do anything
expect re-install OS.

davef
Are you running minicom on the host computer?

I would not expect:
MAC: 08:90:90:90:90:90
to be the first thing you see.

When the boot messages come up on the monitor just copy paste them and
attach as a text file.

Back in 2 hours

Hi Davef,
Of couse there lines are not the first thing i can see. Many lines to
display in monitor but when in monitor display there lines then it repeat
there lines not boot to os.

Normaly when display line
Hit any key to stop autoboot: 0
then 
Boot with zImage
Starting kernel ...    
and
Uncompressing Linux... done, booting the kernel.
and after that i can using OS in this board but if this board error then it
can not boot to OS that it alway repeat there line
Hit any key to stop autoboot: 0

Because i re-installed OS in this board so i can copy full text of this
error.

davef
OK, it seems that the board is not even running the bootloader properly.

I do not have any experience with the 6410 but issues with MLC does sound
familiar.  I can only suggest searching the forum very carefully.

Because i re-installed OS in this board so i can copy full text of this
error.

I think you are trying to say:

Because i re-installed OS in this board so i can copy full text of the
bootup messages.  Because I do not see an "error".

Good luck.

Thanks davef,
It is typo error but this forum can not re-edit.
I will back this error when i can save all text of this issue and i hope
you investigate it with me.
