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
