trying to unbrick a dual nas sata
Newbies first attempt at unbricking a dual nas sata. 
I have followed all the guides I can find (and read) so far and have achieved the following results in the flashtool program (verbose mode):
But I can not seem to get any further.
I have so far placed on the motherboard a 100ohm resister on R35/R36 and placed switch on pin 2 to 17 so I can try breakpoint mode at power up time or after boot up time.
My programmer is an FTDI232RL placed on 3.3v mode. http://www.ebay.co.uk/itm/221179272652?s…984.m1439.l2649
I have shorted RTS/CTS on the FTDI232RL output as described (TDI/TDO)
The chipset on the dual nas is the Storlink 3316-G
I have installed the FTDI drivers (CDM20824_Setup.exe under XP)
My motherboard has Vcc,Rc,Tx,Gnd connections for link to the USB interface
Is my programmer compatible - I know all references state FTDI232R only, but I figure this must be the same?
Any other pointers as to where I might be going wrong?
Regards

Hi,
this nearly looks good.
Your adapter is compatible, otherwise the software would not accept it.
The part in the log
tells me that your cable is working and the test pattern 0x555aaa sent on TDO is received on TDI.
Therefore you get the message "Short plug detected."
If the pattern passes a chip which is set to "JTAG bypass mode" it is delayed one bit and would be received as 0xaaab5554.
You write about Rx, Tx ...
Did you connect to the serial port? You have to use the JTAG connector and connect at least GND, TMS, TCK, TDI, TDO ...
This is a different connector than the serial port!
look here
You are close to success

Aha! 
That will be where I am going wrong - whats the point of the serial interface then?
I will hopefully get chance tonight to go through the jtag interface then,
Good to know the programmers working - thought I may have wasted my money for a moment.
Will let you know the outcome.
Thanks.

Mostly JTAG is the point of last resort, and used to unbrick a NAS whose flash memory no longer has working bootcode.
Maybe try and use the serial port with a telnet client like putty and see if you can bring up the NAS bootloader menu.
If you can, it will be so much easier to reflash the firmwares inside the MTD partitions and restore the NAS to full working glory.
The bootloader usually has a Tftp client so reflashing is via a simple Tftp transfer of firmware bin files.
You will find relevant instructions in the wikis.
Don't give up too easily on the serial connection as often you miss the window of opportunity to enter the bootloader menu.
The same FTDI - USB to RS232 adapter is used to interface to the JTAG or the Serial port.
If you have to use JTAG then HWguru is the
for help with the tricky bits that aren't always so obvious.

Yes HWGuru does require hi praise indeed!
Got my NAS working again last night (of sorts).
Manged to write a redboot image, then got booted to the reboot kernal and updated various parts (image, rd, hdapps).
I have a different issue now though, which I dont think belongs in this thread or forum, but I will tell all anyway.
I was unsure of the exact redboot image to use, but most links i found for dual nas sata were dead. The reboot image i found and uploaded shows many different partitions, which I am sure my previous NAS Config did not show.
I updated zImage, RD.gz, and hdapps.tgz, and it does boot without hard drives attached to what looks like the same nas software I used to have. However, when I plug a hard drive in, it appears that the kernal loads some
config details off the attached hard drive as the network interface goes down and comes back up again with my old network ip that was originally configured on the device. But then, I cant seem to access the web interface anymore.
Without the HD installed, it boots and works fine, but after saving configs (change of IP), and powering off, it doesn't seem to keep the changes. Maybe this is by design and I need to get the exact kernal image I had previously to be able to restore full operation. Anybody know anything about this behaviour?
Anyone, I guess the rest is down to me, so thankyou once again HWGuru!

Thanks HWGuru,
Yes, that is the same device.
I will try that link out probably tomorrow night. (busy tonight with valentines and all that jazz
)
I have a file name like that already (not sure of the exact numbers as I am not at my home PC at present) which is what I used to flash before, which has produced the strange results I described, but I will download and give that one a go and let you know.
Cheers

oh, interesting. so the whole thing is ran from the HD. Would not have guessed at that. 
OK, maybe I will try the second disk only and (as it was a raid1 dual disc) and see if that works. If not, then maybe i will try an alternate HD as you mention.
Will keep you posted.

Alrighty then, back to a working system of sorts 
I turns out my impatients was part of the problem waiting for the web interface. I couldnt seem to get any information from serial interface when booting the box to see what was going in. I tried 8,n,1,with variable bauds, but non seemed to show anything.
I had 1 hard drive showed defunct (no data), but the other showed data, so added them both in together and let the raid re-build and now its workings.
I still have a hardware fault that I can not get the system board to boot without disconnecting one of the hard drives as it seems to draw to much power at boot up. If I boot with one hard drive, then plug the sata power connector in to the second when booted, then restart the nas via the web interface, it all works. I might try a higher rated power pack as my replacement I bought was the correct volt and amp (12v/4a), but it doesnt seem to handle the draw of power at bootup time. All caps appear fine on the motherboard.
Anyway, thanks once again for the assitance HWGuru.
I think I will leave the OS alone now and stick with the stock rom, although I might be tempted to retry an alternate if anyone knows if there is any firmware that makes this box complaint with a PS3 for streaming.

Thanks for the Kudos Aquar 
I think its only fair to reply and keep everyone informed as to my findings (even if it does sound like I am rambling!) as without the help of this forum (especially HWGuru) I would not have my NAS box back.
I can only hope my findings help someone else out in the future. Its been an interesting learning curve about the device.

.Just going to finish off this thread now with some information I gained about my NAS device and FTDI programmer.
Hopefully this will be useful to someone in the future.
When testing the FTDI USB interface, I saw references to shorting tdi/tdo. This translated to tdi/tdo=rts/cts - so short rts/cts on the ftdi programmer
I worked out that the JP1 interface on my NAS box was the following spec:
My FTDI programmer appeared as cable type 4.
When working on linking the USB RS232 lines out to the JP1 interface, this was the translation required:
These are the results I got when testing the programmer against the NAS box, and writing the redboot image.
This is the result of the partitions in flash after the redboot re-image.
