Looking for guys with NETGEAR ReadyNAS Duo v2

Did anyone have this old stuff? I'm looking for someone, who could test my PR:

I can provide images for tests.

I can test again if you provide images. However my system is currently running Debian 10 with a 5.4.x kernel booting from the SATA drives. I would need to know what environment variables to restore.


Thank You for response. Do You have stock bootloader?

Yes, I'm running the stock U-Boot with modified environment to enable booting to Debian 10 from the SATA drive.

I've got a readynas duo v2 as well. The flash has some badblocks which killed the original firmware so it currently has Debian installed. Uboot is original but envs have been adjusted to run Debian. uImage and uIninrd are in flash, Debian rootfs is on an USB drive. The nas is not being used at the moment so happy to give your openwrt build a try.


Thank You for response.

Here are images for installation:

I change envs" "bootargs" and "bootcmd". And nand area after env partition. So, if You want to go back after tests, please make backup of data stored in nand and described args.

I added luci and ext4 support. If You need more kmods, please let me know.

Tested successfully. As stated on GitHub you may add a Tested By from me. Please let me know when this gets merged to trunk as I would like to follow up with the similar 4-bay Netgear NV+ v2 which I have 2 of.


I've successfully installed your image. The only issue I found is that when I power off the box there is an error and I need to pull the power cord before I can start the nas again. I experience the same thing when running Debian Buster so I don't think it has anything to do with your openwrt image.

Thank You for tests. Can I put You in "Tested-by" field?

You're right. gpio-poweroff from upstream are buggy. It isn't work and causes only warning. According to GPL sources of NETGEAR, poweroff should be done as reboot with some registers configuration. To proper poweroff is needed to clear bit in one of registers:

  • PHY register: Page 3 Reg 17 Bit 4
  • RTC register: SL2(BIT5) of RS5C372a control 1 register (0xe0)

For more info please look at file:
from Netgear GPL sources.

I will add info to known issues in PR.

yes fine to add me to the tested-by field.


did the Netgear Readynas Duo V2 get full openWrt support? I can't see any images in the 21.02 RC1 download section.


It is still in the GitHub pull requests (https://github.com/openwrt/openwrt/pull/3371) with status:

Review required

At least 2 approving reviews are required by reviewers with write access.
Merging is blocked

Merging can be performed automatically with 2 approving reviews.

So you'll need to get 2 reviewers with write access to approve. I've done what I can by adding my Tested By.

I bring back device to me. I plan to push it forward.
