Problem with flashing and/or starting UBoot with 2420

Problem with flashing and/or starting UBoot with 2420

[Ola Helm]

Hi all,

My problem is following one:

I flashed the newest H4 UBoot available to ou board and after restart I get
following message in Hyperterminal:

U-Boot 1.1.3 (Sep  6 2005 - 14:24:25)

U-Boot code: 80E80000 -> 80E9F0E8  BSS: -> 80EA3F2C
OMAP2420-GP revision 3, PRCM II
TI H4 SDP Base Board + Menelaus Daughter Board + mDDR
RAM Configuration:
Bank #0: 80000000 32 MB
Bank #1: 82000000 32 MB
## Unknown FLASH on Bank 0 - Size = 0x00000000 = 0 MB
## Unknown FLASH on Bank 1 - Size = 0x00000000 = 0 MB
Flash:  0 kB
NAND:

So there seems to be nothing in the flash neither I am able to write
anything to command line. It seems to be that there might be some kind of
error in mapping of memory or something like that.

Our system consits of following items:
- MAIN BOARD 700-0561-001 Rev C.2
- PROCESSOR DAUGTHER CARD MENELAUS 2420 750-0009-007/B
- MULTIPORT II DEBUG BOARD 700-0582-000 REV B

- Blackhawk USB 560 JTAG Emulator BH-USB-560M

- Code Composer Studio 3.1 Platinum Edition
- TI OSTHost
- TI OSTBoot

We have used OSTTool 2.5 to flash the board, and there has been no problems
with it. We have used following settings:

Interface: USB
Platform: 2420 ES 2.1 Menelaus Combo
Flash: NOR
Device: GP
Multiple downloads: Enabled
CRC Checking: Enabled
ASIC ID logging: On
Default addresses


We have used following postions in two "most important" swithces (related to
flashing) on daugther card when flashing the board:

SW 1
1 ON
2 OFF
3 ON
4 OFF

SW 2

1 OFF
2 ON
3 ON
4 ON

And while listening serial port in SW 1 number 4 is ON and in SW 2 all are
ON. This has worked fine with TI bootfiles.

Does anybody have an idea what is the problem or - even better - idea what
to do to solve it? Thanks already in advance.

Regs,

O

Does u-boot compiled for NAND or NOR? Please undefine
#CONFIG_NAND_BOOT.

Hi,

Thanks for quick answering, unfortunately I haven't been able to mess around
with board.

Yes, seems to be that boot is for NAND and not NOR. Thus it is actually
opposite you said i.e.  I'm trying to flash & boot from NOR but the UBoot is
for NAND.

As it comes to link you send, it does not work for me. The switch positions
are besides for serial flashing also for some other board since OSTTool only
waits for USB device connection. There is probably ome way to do the NAND
flashing with this board too, but I haven't yet figured what it is. NOR USB
flashing switch postions are as I wrote with this board.

But I'll check out the compling with NOR setiings next.

Let me simplify my earlier statements:

o Link I had mentioned gives steps for Meneluas Board, flashing u-boot
to NOR flash i.e Booting from NOR.

o Flashing and booting from u-boot is a different story, as it requires
x-loader (you need to sign x-loader image) and different switch
positions. 

Switch positions are described in EVM user guide. Please refer that.

Above statment is for NAND.

I define my saying

> > opposite you said i.e.  I'm trying to flash & boot from NOR but the
> > UBoot is

a bit also: What I want now is to flash Uboot to NOR on my board and boot it
from there after that, just as you said in

> flashing
> u-boot
> to NOR flash i.e Booting from NOR.

So, I think that's what link was about, right? But, the switch settings
below (copied from that message) are not compatible with our board:

SW4: OFF, OFF, ON, ON
SW1: ON, OFF, ON, OFF(OFF, OFF, ON, ON for booting)
SW2: OFF, OFF, ON, ON(All ON for booting)
SW3: OFF, ON, ON, ON

In our board the settings are following ones, especially SW1 & SW2 must be
like that

SW4: OFF, OFF, ON, ON
SW1: ON, OFF, ON, OFF(ON, OFF, ON, ON for booting)
SW2: OFF, ON, ON, ON(All ON for booting)
SW3: OFF, ON, ON, OFF

It works with original TI files, but I'm not sure is it correct for this
case. They vary from board to board anyway. I think that the flashing  goes
to right place and I think it even boots from the right place (if it would
boot from NAND there would be no message at all), but some settings (booting
or flashing) are not completely correct. Or perhaps the CONFIG_NAND_BOOT
definition..

Re: Problem with flashing and/or starting UBoot with 2420

[Ola Helm]

Thanks for your help and advices. I commented the NAND-definition and
compiled a new boot, it worked.

/O

Or perhaps the CONFIG_NAND_BOOT definition..
