ReadyNas Duo V2 - u-boot doesn't boot any more - SOLVED
Hi,
I had a lot of fun with the DuoV2 installing Debian. :D Everything worked well until I tried to modify the u-boot-env to automatically boot my kernel and system.
(I know I void my warranty with doing this. But it's worth it, as it would be a great server. I don't want to do anything evil, I do it just because I like tweaking)
Now u-boot stops at printing "net: egiga [PRIME]"
This text never appears: "Hit any key to stop autoboot:"
So there is no way to get the u-boot console and fix the u-boot-env.
I already succeeded in switching Bootstrap 1.21 into debug-mode or boot-from-uart-mode.
I uploaded the stock u-boot image where I replaced the NAND header with a UART header using your doimage tool.
Well, it booted the same way, since it's the same binary. Stopped just before the autoboot. :(
It was a bunch of work to get to this point. But now I'm stuck. :?
Could you please give a hint on any of these questions?
Thank you very much, you would make me very happy!

Could you please give a hint on any of these questions?
- Can I use the bootstrap debug console to fix the u-boot-env? How?
- The J1 10 PIN connector. Is it JTAG and what is the pin-out?
- Is there any other way of fixing the u-boot-env?
Thank you very much, you would make me very happy!

- Hi,
I think also, i had crashed the bootloader.
The following variants dont going:
TFTP Boot Recovery because the LAN dont working anymore (The LED's backside, dont blink)
USB Boot, the Power Button LED dont work anymore (I can't count for the USB Boot)
Factory Default its the same as USB Boot.
I think the only way is the Console Connection backside with the Serial TTL.
And then install the boot loader. But the problem is, i don't have the file.
I wait for the Cable USB to TTL and write here my results.
Thanks for your help
Greeting Nik - Hello,
I have now the TTL Adapter, but i can't nothing seen when the nas booting.
I have a linux machine, and i type: screen /dev/ttyUSB0 9600 8N1
Only a Black Screen.
Can anybody help me, to repair my NAS
Thanks - When did you purchase the Duo and did you purchase it brand new? I think your Duo is bricked.
- Hallo,
Thank you for your help.
I recycled the old nas and buy an new. And i don't install the ssh access anymore.
Thanks and have a nice day - Using SSH is O.K. provided you don't misuse it. Trying to overwrite the BIOS or u-boot or other bootloader can be quite dangerous if you are not careful.
Before trying boot recovery always seek help. Boot Recovery is rarely needed and when it's not needed is likely if anything to make the problem worse.
