[U-Boot] help with HP mv2120 debricking

[Miroslav Petricek]

Dear members,

 

I was playing with my MH mv2120 NAS device and it happened to me that I
stored some u-boot values and the device now hangs on boot. I am stupid I
know.

 

Last thing I did was that I've set:

 

setenv enaPost Yes

setenv enaCpuStream Yes

 

and saved them:

 

saveenv

 

Now my device hangs like this (taken from serial console)

 

.

\___/    |____/ \___/ \___/ \__|  ** Forcing LOADER mode only **

 ** MARVELL BOARD: RD-88F5182-NAS-P2 LE

 

U-Boot 1.1.4 (Oct 12 2007 - 12:30:28) Marvell version:
2.3.11_HP_1_3_1_Built at HP

 

U-Boot code: 00200000 -> 0026FFF0  BSS: -> 0027FDBC

 

Soc: 88F5182 A2 (DDR2)

CPU running @ 500Mhz

SysClock = 166Mhz , TClock = 166Mhz

 

DRAM CS[0] base 0x00000000   size 128MB

DRAM Total size 128MB  32bit width

Memory test pattern: 0x55555555, 0xAAAAAAAA,  Pass

[512kB at fff80000] Flash: 512 kB

Addresses 4M - 0M are saved for the U-Boot usage.

Mem malloc Initialization (4M - 3M): Done

 

CPU : ARM926 (Rev 0)

Orion 1 streaming enabled

 

And here it hangs. I wonder if there is any way hot to reset u-boot
settings. I mean some interrupt the POST by some magic key from serial
consoler or something.

 

Do you think there is any possibility to debrick my device?

 

Thanks,

 

Mirek

Why don't you ask your vendor ?

It sounds like you may have to investigate a JTAG cable. Try opening it
up, and seeing if you can find a 12 or 14 pin header. It *MAY* be a jtag
header.

Google for more information about JTAG and the Orion5x devices.

If the U-boot configuration settings are stored at the top end of the
flash memory, you might try to shorten the highest address line of the
flash to the ground with a needle. Then U-boot will read a corrupted
environment and fall back to its defaults.

(try at own risk)
