Micro S3C2440A NAND Flash Porgramming

Bhimashankar
Hi all,

I am using Micro S3C2440A (ARM920T) kit.But i have a problem for
programming. When I download program by using DNW software it stored on
SDRAM.

But i want to download the program into NAND flash
How can I do this.

If anybody knows solution please help me.

Thanks.

<<When I download program by using DNW software it stored on

How did you come this conclusion?

My understanding of SuperVivi using DNW is that everything is placed in
NAND flash.  Do you have the <Mini2440 Downloader instruction> sheet?

Bhimashankar
Thanks for reply.

When I open DNW & press reset from kit, the DNW downloading menu comes,
containing the option for donwload the program in SDRAM & Run. From this i
had conclusion.

Thanks.

davef
OK.  The Mini2440 Downloader Instructions bascially just say, to flash the
factory distro> to do a: 
x (NAND flash parition)
v (Supervivi)
k (kernel)
y (rootfs, ie Qtopia)

Guess a solution is not to use the (d) option.

Are you downloading your own program?  I just use the USB or SD card to put
my applications in my <home> directory and run them from there.

I need to ask what you mean by <program>?  And what are you trying to do?

Bhimashankar
Yes, i have made my code in C. Currently i am not using any OS. 
That all codes are working perfectly without any problem.

My bootloader is in NAND flash. Which gived me downloading options in DNW.

Is there any bootloader that gives me directly the NAND flash programming
option?

Thanks,
Bhimashankar

Dear Davef,

  I am trying to put my final application in NAND but once power Off and ON
the application starts working and hangs in the middle of the application
please if u know highlight on this issue.

set swith to NOR.  use option "download and run" in supervivi menu.

in my case I think i did this.

Bhimashankar
Dear,

 I was asking about booting from NAND.

Vikas
Dear,

Even if you will boot from NOR, after downloading, image will get written
into NAND.  So next time after booting from NAND, it will get executed.

Bhimashankar
yes i have done the same thing bootloader is NOR 1st booted from NOR and
selected option to load to NAND flash loaded the file and put switch to
NAND and power the board.
after this application starts from NAND but it hangs in the middle.

Vikas
Try using sample application supplied in the CD.  They work without any
problem.

I have also tried sample applications supplied with ADS, they are working.

How about debugging using JTAG cable ??

Bhimashankar
the application which is given in the cd works fine but i have followed the
same file sequence for system files still is hangs up

Vikas
Since u r in india, can we have a call to discuss this over phone? mail me
on kvshetye at yahoo dot com.

Bhimashankar
please check ur mail

dejet
Would you be so kind and post the solution here? I am having the same
problem :/

hex
just and idea, try using 'dd' to adjust your executables to the pagesize of
your nand flash?

for 2k block size for example:
dd if=myprog.bin of=myprog2k.bin bs=2K conv=sync

Hello, 
i have bought mini2440 board and LCD 3.5'' touch screen.

1st:
I try to install windows ce 5.0 but when i choose nand flash windows, my
computer (xp installed) can't define the hardware? is this a problem?

2nd: 
And I use nor flash to install winCE 5.0.
I installed winCE 5.0 îmage by swithing nor flash.
But when i  reset it does't start itself. &#304;t needs to be chosen  " [b]
Boot the system " from supervivi menu  to start winCE5.0
(i think i have to write into NAND FLASH but if i swith to NAND supervivi
says that "unsupported NAND")
Plase help me to install Windows CE 5.0 correctly and non-volatile one.

i am beginner I am using EM-2440 (S3C2440A ARM920) kit. i am develop simple
basic programs such as led toggling and blinking according key buttons But
i have a problem for loading .file into NAND. When I download .file by
using DNW software it stored on SDRAM.
           But i want to download the .file into NAND flash
How can I do this.

If anybody knows solution please help me.

Thanks.
