Not able to run u-boot

Forum: Linux
nithin 
Hi all,

I have a new mini2440 board. While I am switching to NOR, am able to get
choices and can enter into supervivi. I have a compiled u-boot and also the
u-boot.bin provided with the board. 

I tried to load u-boot into Ram by load command in supervivi as given
below.
> load ram 0x33f80000 179444 u

and in the terminal I passes uboot by 
 s3c_2410_bootusb filename

It is successfully getting loaded. But if I tried to do `go 0x33f80000` the
output is as given below.

  argument 0 = 0x00000000
  argument 1 = 0x00000000
  argument 2 = 0x00000000
  argument 3 = 0x00000000

and standing as hanged.. .. I tried with 0x30000000 address also. But the
result is same. 
While I tried to switch to NAND flash, nothing is displayed. May be NAND
flash contents got erased (not sure). 

Can anyone please give a solution for this issue. Unless I am loading the
Uboot, I cant proceed further. So expecting your help.

davef 
Not sure where the 0x33f80000 comes from.  I use 0x31000000.

davef 
Which mini2440 variant are you using?  I was referring to a 64M unit.

Nithin 
I used 0x31000000 also. But its showing the same result. Variant which I am
using is mini 35 .

davef 
Don't recognise <mini 35>.  How much RAM and flash does it have?

nithin 
64 MB SDRAM 32 bit

and 64MB NAND flash and 2 MB NOR flash

1024 byte EEPROM

Dirk 
I think, it's a known issue with u-boot.
you need to install it to NAND with the download-option in vivi
and start it directly from nand.

If you just google for your problem, you should find a tutorial for that.

davef 
By "hanged" do you mean you see a prompt waiting for the next input or ?

It was not showing any response after above mentioned lines. Even if I
typed anything , no change. Only option was to restart.

nithin 
I tried download and run option from NOR flash. The output was

Use these steps to program the image to flash:
1. In OpenOCD
   Run the 'halt' command to halt u-boot
   Run the 'load_image <file> <address>' command to load file to SDRAM
   Run the 'resume' command to resume u-boot
2. In u-boot, use the flash commands to program the image to flash
Or, use the tftp or nfs command to download file, and then program the
flash.

As I was not able to use load command in supervivi, I used d option. 
But I am not able to create partition for Uboot. So that option is also
getting failed. 
I am not sure whether this is the correct method. But whatever methods
mentioned in the links are not able to load Uboot in my case.

davef 
Perhaps if you follow the tutorial in the link I mentioned and when
something doesn't work as expected from there, I might be able to help.

Maybe, you need to start from square one and JTAG Supervivi into NOR.

Can you load the pre-built YAFFS2 images from FriendlyArm?

If you look at my previously mentioned link you might find that the
software he links to is not there.  The u-boot.bin version you want is
239016 bytes.

As Dirk mentioned people have had grief trying to get their own u-boot to
work.

If you can't find the required u-boot send a PM to:

Hi davef ,

I followed the link which you mentioned above. It was working till nand
createbbt. At that moment its showing as

The same error was getting earlier.

Is this a big issue, which will stop my further steps ? Can I continue with
this error ?

A 1Gb machine takes minutes to create the BBT. Leave it for 5 minutes. 
Also, you start off in the NOR position and only change to NAND position
later on.

nithin 
Thank a lot davef. Its able to use Uboot now. 

But I have to upload u-boot.bin  each time from NOR and then switching back
to NAND. While I am trying to boot directly from NAND without loading
anything from NOR, its not showing anything. I tried nand write.e command
from Uboot, but its still same.

Whether is this the procedure we have to follow, or is it a problem only
for me.

davef 
Think what are seeing in a common problem for mini2440 greater than 64M.

Must be something about it here:
http://billforums.station51.net/viewforum.php?f=1

Another place to search is:
http://groups.google.com/group/mini2440
and look for <256M> as that is when the problem surfaced.
