Hi all,

I've got a new DNS-320 from Chinese market.

    - hardware version: B2
    - software version: 1.00

Wishing to replace the firmware with Debian. So I found the the Serial port pinout in mainboard.
To communicate to the NAS, open the serial port at 115200 baud, 8-n-1, flow control off. Power on the nas.
I am able to see it boot, however it seems that D-link put in some petty measures to stop tinkering.

    U-Boot 1.1.4 (Apr 19 2012 - 11:21:19) Marvell version: 3.6.0.DNS-320B.01

    U-Boot code: 00600000 -> 0067FFF0  BSS: -> 006CFB00

    Soc: 88F6702 A1 CPU running @ 1000Mhz L2 running @ 500Mhz
    SysClock = 400Mhz , TClock = 166Mhz

    DRAM (DDR2) CAS Latency = 5 tRP = 5 tRAS = 18 tRCD=6
    DRAM CS[0] base 0x00000000   size 128MB
    DRAM Total size 128MB  16bit width
    Addresses 8M - 0M are saved for the U-Boot usage.
    Mem malloc Initialization (8M - 7M): Done
    NAND:128 MB
    Flash:  0 kB

    CPU : Marvell Feroceon (Rev 1)

    Streaming disabled
    Write allocate disabled


    USB 0: host mode
    PEX 0: interface detected no Link.
    Net:   egiga0 [PRIME]
    Hit any key to stop autoboot:  0

- "press any key" won't stop autoboot.

After the system is booted, console prompt me that "Please press Enter to activate this console."

- but "press any key" won't active this console

So is there any break-in code/method to enter u-boot console and shell?

Thanks!

[albert]

Try this, press space-bar key and 1 to get into u-boot console prompt.

[tthsn]

Hi albert,

Yes I've tried, but "Space+1" won't stop u-boot.

How to verify uart hardware of dns-320 is OK?

[albert]

DNS-320 H/W A1 use the same U-Boot version and "space+1" worked.

Code: [Select]

Marvell_DNS320>> version

U-Boot 1.1.4 (Jun  7 2010 - 10:33:37) Marvell version: 3.4.14.DNS320_02
Try pressing the keys way before the "Hit any key to stop autoboot:  0" prompt appear.

[tthsn]

Yes, I've tried press "Space, 1" before the prompt. Still won't stop u-boot.

Maybe the Marvell 88F6702-A1 SOC can only send (TX) data but can't read (RX) data.
- How to test the UART part of the SOC?

Or the "unlock code" has changed?
- How to reverse to find the "unlock code"?

 

[albert]

Think you got the pin-out from PL2303 and NAS set wrongly, only TxD (yellow) is set correctly.

PL2303   NAS
Vcc   -   not use
TxD   -   RxD (pin 1)
RxD   -   TxD (pin 5)
Gnd   -   Gnd (pin 4)

[tthsn]

Yes, albert, you are right!!

And here is the UART pinout, the connector is soldered by a friend of mine.



1 - RX
2 - empty
3 - ?
4 - GND (no hole in the board, so connect GND to FAN connector)
5 - TX

[albert]

Do you mind posting a detail picture of the PCB as well as the console log during the system start-up? Thank in advance.

[albert]

Any update on this?

[tthsn]

Sorry for the late reply. I came back from a visit to my parents' home, where we don't have a cable connection.

Here is the shot.
