Hello,

i have a old Netgear readynas model name RN10400 model no RND-4D. Well okay, This nas i have a problem with because it not start up. it is 4x3Tb HD. disks. And every disk start up and runing well. But i can't get enything out of it.
And in the display is standing. "Boot from USB failure....."

I don't know what ReadyNas os ver. firmware is installed. But i have read from netgear support that shall be first updated to ReadyNas Os 6.2.5 or 6.3.5 then upgard to ReadyNas os 6.5.2 and to 6.10.X or else it go broken.

And the netgear say this product/software is end of life.

So is there enyone who can help me with this.? And help me make a USB so i can upgard my Nas and get it up and going again.
Netgear not support enything, Not sell new motherboard nothing. I saw on internet a shop in England who had new motherboard to my RN10400 but they was out of stock. Mayby not so strange when they go broken very fast.

Well can somebody help me with this. I hope so.

Thanks..

AkkJaa,

Normally people come here to replace stock FW with the latest Linux system on old boxes. So I dont know much about stock FW.

> So is there enyone who can help me with this.? And
> help me make a USB so

ReadyNAS has a Reset button so you can reset everything to factory condition:

https://kb.netgear.com/22891/How-do-I-access-the-boot-menu-on-my-ReadyNAS-104-204-214-or-314

Have you tried that yet? if you have a lot of data on the HDDs you want to keep then be careful doing reset (I would remove them out of the slots before trying). Usually thi s process does not touch data, but good to prevent it any way.

And also, usually they have a way to rescue the system by USB that was specially prepared to be loaded and re-install the stock FW.

=====

After trying all of the above, if you still cannot rescue it, then you will need to open the case and to connect a serial console in order to see what's going on and interact with the system during boot. Most of the time, this will allow you to rescue the system easily.

Hi Bodhi,

Thank you for list up for me what to try on my RN10400. Yes it's very much data on the HD's on it. So i want to keep that. Now it is 4 x 3 Tb. HD's. in it. But i can replace them with 4 x 500 Gb. new empty HD's if it's must be HD's in it when i do the reset.

Well okay thanks i will try what you have write up for me now and see.

Then i will come back to you and tell you what happend.

Thanks again.

Hi Bodhi,

Now i have try it. I take out the HDDs and i connect the power line. the first who standing in the display is.: Netgear Storage Welcome. this message is for 1 - 2 sec. Then come this in the display.: Boot from USB Failed! and that's all.

I can't turn the RN10400 off. it go on right away when i connect the power line. And i can't reset it, because if i hold in reset and push power then it are already start up when i connect the power line. and i get every time the message.: Netgear Storage Welcome. Then message.: Boot from USB Failed!

I also try to hold in Reset and Power when i connect the power line but just the same as before. And in the display is standing Boot from USB Failed! and the Power and backup button's blinking very fast all the time.

And that was the same when the HDDs was in the cabinet. But then the light for HHDs was on and i coud hear the HDDs war running. So here is mayby something who hanging in the motherboard. I also try to remove the backup battery and put it inn again but just the same.

So then i have try all what you have told me. So then i need to try to connect a serial console to see what's going on and interact with the system during boot. You say.

Yes, what do i need to do that.? And where can i buy it.?

Okay hope to hear from you again.

Thanks again.

AkkJaa,

See this thread for serial console parts discussion:

https://forum.doozan.com/read.php?8,13263

If you can find it in Amazon at your locale (e.g. Amazon Europe) then it is quicker shipping but cost a little more. If you buy from eBay shipping from China then it will take about 2-3 weeks.

Either the CP or PL chip would work.

CP2102
PL3xxx

An example of the CP2102 on Amazon. It comes with the 4 wires, but you must use only 3 wires: RXD, TXD, and GND (do not connect 3.3V).

Hi Bodhi,

Now i got 2 diffrent type from Ebay.
1 is CP2102 USB 2.0 to TTL UART Serial Converter Module 5P STC PRGMR.. with 4 cables. and
1 USB 2.0 to TTL UART 6PIN Module Serial Converter CP2104 STC PRGM. with 4 cables.

CP2102 module have. 5 pin.
3V3
TXD
RXD
GND
+5V

CP2104 have 6 pin.
DTR
3V3
5V
TXD
RXD
GND

I put up 2 picture files on the modules so you can see them. Yes... Now i take out the motherboard in the the Netgear RN10400. But what program do i use to connect with this modules.?? And where to connect the modules to the motherboard.?

I can take out the motherboard and take a photo of it and put up in here. So you can see how it look like.

Okay thanks again.

CP2102 is easier to use.

The USB is connected to another Linux box (host). The 3 wires TXD, RXD, and GND are connected to the serial header on the RN104 board.

Run minicom or picocom on the Linux host.
picocom --b 115200 --f n --p n --d 8 /dev/ttyUSB0

If you'd like to. If you can see the serial header pins and marking then it is easy. If not we can look the board and tell you where.

Hi Bodhi,

Okay yes, now i have take some photos, 15 Photo's of the motherboard and parts connected to the motherboard.

When it come to Linux then i have a computer where i have installed Linux Fedora Core 9. on. Can i use that computer.?

I upload photos here now, I have take more photo's. But i see there is only 2 places to connect to the motherboard who is not connect'ed with something else, is on Photo 13. and that is J14 and J7 on the board. Can only upload 3 pic. but i have more and can take more. if you need some details of enything on the motherboard or other things with it.

Because the other connection's is to front display, and front light's and power and backup switch. And HD card.

Yes i am not sure where the serial header is, i have upload'ed 3 pic. here and have more.

Oki, you can see if i got it right now. i will upload more photos if needed.

Many Thanks.

Photo 4. Upper right corner looks like serial console header. But the pic resolution is too low, I can't see clearly.

Usually, serial console header marking on the board is J and a number (e.g. J20).


Photo 13 on the right side. Thatt's must be the serial header. It is marked with J7.

And yes, Fedora would be fine.

Plug the CP2xx into a USB port and run

dmesg


At the end of the log, you can see the device is ttyUSB0, or some other assigned name.

To confirm:

Hi Bodhi,

Thank you again,

Here i have take some new photo's, This pic. is alittlebit better. If you see on photo 17. The first Right from the battery is J12 there is the connection with 12 pin. for the digital display down in the front. Then number 1 under the battery is J9 connection with 12 pin. for connect the upper front with led lights for power, Hdd, and switch for power and backup, the same is number 2 under the battery that is J10 with 10 pin's.
Then in the right corner is J7 with 4 pin and J14 with 4 pin.

Photo 16 and 18 is better now so you can see what is write on the motherboard with J7 with 4 pin. and J14 with 4 pin.

So then i use my Fedora computer to do this. What program in Fedora C9, do i use for the CP2102.?

Ok Thanks.

Re: RN10400

Hi Bodhi,

Yes, but if the J7 is the serial header, there is 4 diffrent pins. you have.:-

1 with name R305
1 with name R299
1 with name R303
1 with name R348

So how do i find the right one to the cable's i must connect.?

Because if i connect wrong and if it is some power there i can damage something.

Okay thanks,

AkkJaa,

There is extensive documentation regarding this device at http://natisbad.org/NAS3/index.html. This includes information regarding serial access. The RN102 is similar and his page for that device gives a better visual of connecting the serial dongle.

Check natisbad.org like Ray said above, to see if you can tell if your box is the same as what described on that page. If it is, then you don't need to figure out the pinouts.

====

The serial header pinouts is relatively easy to figure out if you have a multimeter.

With the box powered on, use the meter to find the 3.3V pin (most likely pin 1 or pin 4). And then the GND pin should be the other one (1 or 4). Use the multimeter continuity check to confirm the GND.

The TXD and RXD are usually in the middle 2 pins. The RXD pin voltage would be 0.0 V. The TXD is near 3.3V when it transmits data.

Hi Bodhi and Ray,

I will check out the web page, Yes i have multimeter. 3 of them. and i will find out what pin is what.

Thanks again.

Re: RN10400

Hi,

Now i have use a multimeter. So J7 is like this.:-

Between R305 and C348 is + 3,3V.
Between R305 and R299 is + 3,3V.
Between R305 and R303 is + 3,3V.

Between C348 and R299 is 0.
Between C348 and R303 is 0.
Between R299 and R303 is 0.

So then is the R303 GND.

Here i upload 3 photo where i start up NetGear RN10400 and you see what it is in the display and the power and backup led flashing all the time.

Thanks.

Hi Bodhi and Ray,

I have look at the links and the serial is J14 and not J7. And it can be connected without take apart the Netgear cabinett, Okay then i will try read some more and see how to do this. Because it is something very wrong with this RN10400 motherboard.

Okay thanks again.

Cool!

The behavior of the box now seems to be: it tried to boot from NAND, but it failed to do so (probably the envs are messed up). So it looked for a recovery USB but could not find it either.

Now you need to run picocom on Fedora and get the serial console log, and post here.

Re: RN10400

Hi Bodhi,

Now i have start up my Fedora C9 computer, And i can't find the Picocom program. I file search on the computer but can't find it. And when i search on dmesg and lsusb it cone up with 2 Directories. with a lot of files in each directorie for each program. But what file start the program's and where do you run the programs from.?

Then something must be wrong about the connecting with the CP2102.
Now i have connect the CP2102. like This.:-

CP2102 GND to the GND on the motherboard.
CP2102 RXD to the RX on the motherboard.
CP2102 TXD to the TX on the motherboard.

Just this 3 cable is connected.

Then i connect the USB cable to the linux computer and a red light come on on the CP2102. Then the RN10400 do not start up. iven if i push power it will not start up. Nothing, It just flash 1 time for about 1 sec. in the display where the message. Boot from USB Failed!. is write as in the photo i uploaded, then nothing.

Then when i disconnect the USB cable from the linux computer, then the RN10400 start up right away when i plug in the power cable just like before. BUT now also start the red light in the CP2102 without the USB cabel connected in the linux computer.

So if there shell be no power on the 3 cable i have connected then it shell be no light to. Therefor there must be something wrong the photo on the link because i have connected just like in the photo. But the pic. is not the same as on my motherboard. But hi write that is the same from RN10200 to RN10400.

I think i shell use the multimeter on the J14 and see what is wrong there.
Yeah, when it come to led lights it can light with very little power, so i think i see with the multimeter again.

Now i upload the photo from behind of the RN10400 and with conneced the CP2102 without connect the USB cable in the linux computer. but the RN10400 is on. So you see the red light is on.

Okay thanks.

AkkJaa..

Okay now i have Measured the pins with the multimeter from RN10400 and on the Photo from the link that must be wrong. Because that photo say that the pin up to left is RX and the up to right is TX then pin down under to the left is GND and pin Down to the right is +3,3V

Well, i use a multimeter now and i find +3,3V between RX and GND and nothing on the other pin's. And when i swich the multimeter cable between GND and RX then i find -3,3V. so the + side on this must be GND on the photo from the link. and the - side is RX on the Photo from the link. Because i can't find enything on the other pins from the motherboard.

But the motherboard is not simular from behind. is you see on the photos.

Okay again and thanks.

If you cannot find the minicom or picocom then you need to install it on Fedora. At command line:

which minicom
which picocom

Like I've posted in previous post, to run the serial console host, at command line (same for minicom and picocom):

picocom --b 115200 --f n --p n --d 8 /dev/ttyUSB0

That's the correct connection for the CP2102. But for experiment to see if it is different, you'd want to try to cross wires: TXD to RXD, RXD to TXD.

On the PL3xx module converter, you do need to cross the wires TXD and RXD.

This box has different serial header connection than most other boxes (if J14 is correct header like natisbad said). Usually, the serial header looks just like J7 in all other boxes.

I'll take a look at that natisbad webpage and tell you what I think.
