NOR flashing problem

Hi,

I downloaded the supervivi-128 e uboot-128 for my mini2440 256MB. I tried
to flash the nor memory with supervivi-128 using the guide in the Downloads
section but when I turned on the board with the S2 in nor position the
hyperterminal said "NAND NOT SUPPORTED". I tried than to flash the nor with
uboot-128 loader, alwais following exactly the guide, but nothing happened.
 Now I'd like to return to the first loader but I can't flash the nor
because H-JTAG program says "can't programm the destination address". I
didn't change the settings during the two flashing...

What should I do now??? Please help me I don't now what to do.

Regards,
Marco.

Hi Marco,

You need to disable the target MMU when flashing the NOR. The most likely
problem is with the Init Script settings. Here is a possible solution:

1. Start H-Jtag and launch H-Flasher utility.
2. Choose the correct NOR part in step 1 - Flash Selection. (SST-39VF1601
in my case. Check yours.)
3. In step 2, enter correct addresses (Flash = 0x00000000 and RAM=
0x30000000)
4. In step 3, ensure that correct init script file (*.hfc from your
FriendlyARM DVD) is selected.
5. In the same step, use the arrow buttons on the right to add a Flash
command (Left arrow). Enter the command by double-clicking the "Cmd"
column. Choose "Disable MMU" command. Move this command to the top of the
script command list using the Up arrow.
6. Now proceed to step 4 and Flash your NOR as usual.

That should do it.

Good luck!

Hi,

It warks!!!Thanks a lot Gautman

Marco

I'm sorry..i also have this problem now..

And I have tried the solution as mentioned by Gautam

but I can't find the cmd function "Disable MMU" in step 5.

Can you tell me where this function is ??

I'm using H-JTAG V1.0 Release ...


Thank you very much~

Hi yuensli!

You need to use H-Jtag v0.4.4. You can download it from here:

Then follow the steps mentioned earlier.

Good luck!

Hi,

I had a different problem when trying to reprogram FLASH worked first
couple of times then gave a 0x120B0000 error. Seems the MMU is a pain in
the ****, I am trying to load and run another Bootloader/ROM monitor
RedBoot. This runs when I load it into RAM from supervivi but does nothing
when I load it into ROM and reboot, probably also caused by me not
configuring the MMU properly though there is code in RedBoot to do this.
However at least I am back to a working system, wonder why the DisMMU
command wasn't in the script to begin with.

Thanks again for that thought I would have to figure out how to do this
manually.

Hi Dodi,

The H-Flash software ha a button to detect the NOR flash device. Make sure
that the .hfc and .his files are loaded in H-Jtag before proceeding. Also
ensure that the "Disable MMU" (DisMMU) command is added to the top of the
script. Then click on the button to check the NOR flash chip.

Sorry for the delay in replying as I was busy with my day job! ;(

HTH!

dear friends,

*.his files. can anyone send these files to my e mail? fatihkeser@yahoo.com

Hi All

I have same problem on mini2440 board J-tag.I did all upper steps
exactly.but the H-Jtag program detect my board and the flasher program can
not detect my board yet! and issue this error message consecutively : can't
halt target and make it enter debug state.
also I did mr.Gautam commands step by step exactly. but that message issue
again! and I can not flash my nor

Hi mohamad,

When you connect your JTAG cable to the mini2440 board, does it show the
Processor ID correctly in blue letters in the H-JTAG software? If it shows
0x00000000 or 0xFFFFFFFF in red colour, it means that the board is not
detected correctly.

This is most likely caused by incorrect parallel port pin settings in the
H-JTAG software. For correct settings, refer to the Mini2440 User Manual or
the document called "Jtagging the NOR". Both these are available in the
Download section on the FriandlyARM web site.

HTH!
