Restarted today the NAS to try your advises and stuck in another boot loop... After executing kwboot and sending image to device, it starts booting and then:

May be uboot.bin taken from uboot.bin is not the best option?
Are there any other images to use with kwboot?

Is that the same one being used in this thread before? If it is then it probably expected some envs to be set certain way, and then now the envs are not.

======

Before I build a different u-boot image for you to boot (our forum member ingmar_k has been rolling a new u-boot 2017.07 for this box).

How far did you get with the steps I've posted above? did you boot into Debian on USB?

With the Debian rootfs on USB drive. kwboot, interrupt serial console and

And then set up the envs to boot Debian rootfs on USB (this instruction is inthe Wiki thread):

setenv usb_set_bootargs 'setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 earlyprintk=serial'
setenv load_uimage 'ext2load usb 0:1 0x800000 /boot/uImage'

Hi Bodhi,

Sadly no progress, whatever way device boots (itself from nand or via kwboot) it stucks in same loop.
USB boot with pressed Backup button is ignored.

Re: How to unbrick the Netgear Ready NAS Duo v2

egor.tio,

I think you need to power down and unplug for a few minutes, and then kwboot again with that u-boot.bin.

==========

However, here is a test u-boot for 2017.07. Run kwboot the same way you did before.

kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.2017.07-tld-2-rc1.readynas_duo_v2.mtd0.kwb -p
Once it starts and you can get to the count down, interrupt it, and

printenv

Please post the entire log here.

Excellent!

Now plug in the Debian USB rootfs and

boot

And see if you can boot into Debian.

Please post this boot log.

> If possible, I would like to keep booting NAS from NAND.

That will come after you can boot in to a working system. And then you can reflash flash mtd0 with a good copy.

Spent some time prepping USB with rootfs, was able to login to the Debian installer :-)
Don't want to reinstall it, so restarted again via kwboot and with magic command :

was able to boot in my Debian on one of the installed drives.
Forgot to save boot log, sorry.
How can I write proper env values to NAND, please? Or I should reflash it fully?

Again, this is not clear enough! which Debian system? stock or Debian-5.2.9-kirkwood-tld-1-rootfs-bodhi.tar.bz2 ?


> Forgot to save boot log, sorry.

In each case above, I will need to see the boot log, and perhaps will ask follow up questions before I can recommend the next step (incorrectly assumption will cause problems).

Please forgive me for making wrong steps, I'm trying to follow your advises how I can understand them :-)
If booting from an USB drive is important step, please advise how to prep it, as uInitrd I found is from debian installer and after booting with kwboot and new uboot.bin you gave, I get Debian Install wizard starting.
For now I'm able to login in my Debian installed on a hard disk in NAS previously after stopping autoboot and issuing that magic command. That Debian is stock one I suppose, can I check that somehow?
Re: How to unbrick the Netgear Ready NAS Duo v2
September 14, 2021 02:26PM
I see. You are thinking Debian mainline installer.

The Debian rootfs can be created using Debian-5.2.9-kirkwood-tld-1-rootfs-bodhi.tar.bz2 from my release thread:

https://forum.doozan.com/read.php?2,12096

It is a complete basic Debian system with kernel 5.2.9-kirkwood-tld-1. It has this box supported.

Once you logged into this Debian rootfs, it should show the correct mtd partitions. And that'll make flashing stock or new u-boot easier.

And something you mentioned above:

was able to boot in my Debian on one of the installed drives.

I did not quite understand the above. The log would be self explanatory.

Cool! the HDD is untouched when you boot with USB rootfs. But removing the hard drive is a good precaution.

Everything looks good. Except the mtd partitions look incorrect. This is the Zyxel 3xx NAS settings. So we need to adjust them.

Let's look back to previous boot logs to see what the original mtd partitions look like for this box and then we need to set it in serial console.

Let me read them again, and you can do the same.

By the way, this box can be run with Debian mainline, if you choose to do so. Some small tweaks need to be set up, though.

Before flashing stock u-boot image (compiled by yury_minsk), the mtdparts envs and /etc/fw_env.config must have correct values.

Here was how yury_minsk did the flashing with my instruction:

https://forum.doozan.com/read.php?3,74954,78274#msg-78274

=====

So there are a few items to do.

So I should boot from kwboot, stop autoboot, then
setenv mainlineLinux yes
setenv load_uimage 'ext2load usb 0:1 0x800000 /boot/uImage'
setenv load_initrd 'ext2load usb 0:1 0x2100000 /boot/uInitrd'
setenv set_bootargs 'setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10  mtdparts=orion_nand:0x180000@0(u-boot),0x20000@0x180000(u-boot-env),0x600000@0x200000(uImage),0x1000000@0x800000(minirootfs),0x6800000@0x1800000(jffs2) earlyprintk=serial'
setenv bootcmd_exec 'usb start; run set_bootargs; run load_uimage; run load_initrd; bootm 0x800000 0x2100000'
setenv bootcmd_stock 'nand read.e 0x1200000 0x200000 0x600000;nand read.e 0x2000000 0x800000 0x1000000;bootm 0x1200000 0x2000000'
setenv bootcmd 'run bootcmd_exec; run bootcmd_stock; reset'
boot

And then from Debian I should flash NAND as yuri_minsk did:
dd if=u-boot-db88f6282abp_533ddr3db_nand.pached.bin of=uboot-netgear-rnd2.mtd0.kwb bs=512k conv=sync
flash_erase /dev/mtd0 0 4
nandwrite  /dev/mtd0 uboot-netgear-rnd2.mtd0.kwb

Not quite. Yury kwboot with stock uboot. The above envs would work only with stock uboot. You kwboot with new uboot so the envs are different.

I will be back tomorrow.

Ok, will wait. Thank you!
Re: How to unbrick the Netgear Ready NAS Duo v2
September 15, 2021 03:21PM
For stock u-boot.


1. Create flash-ready uboot

dd if=u-boot-db88f6282abp_533ddr3db_nand.pached.bin of=uboot-netgear-rnd2.mtd0.kwb bs=512k conv=sync


1. kwboot with uboot-netgear-rnd2.mtd0.kwb

2. Intrreupt u-boot and,

setenv mainlineLinux yes
setenv load_uimage 'ext2load usb 0:1 0x800000 /boot/uImage'
setenv load_initrd 'ext2load usb 0:1 0x2100000 /boot/uInitrd'
setenv set_bootargs 'setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10  mtdparts=orion_nand:0x180000@0(u-boot),0x20000@0x180000(u-boot-env),0x600000@0x200000(uImage),0x1000000@0x800000(minirootfs),0x6800000@0x1800000(jffs2) earlyprintk=serial'
setenv bootcmd_exec 'usb start; run set_bootargs; run load_uimage; run load_initrd; bootm 0x800000 0x2100000'
setenv bootcmd_stock 'nand read.e 0x1200000 0x200000 0x600000;nand read.e 0x2000000 0x800000 0x1000000;bootm 0x1200000 0x2000000'
setenv bootcmd 'run bootcmd_exec; run bootcmd_stock; reset'
boot


3. In Debian, check the mtds to make sure they look like this,

cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00180000 00020000 "u-boot"
mtd1: 001a0000 00020000 "u-boot-env"
mtd2: 00800000 00020000 "uImage"
mtd3: 01800000 00020000 "minirootfs"
mtd4: 06800000 00020000 "jffs2"



4. Fllash NAND as yuri_minsk did:

flash_erase /dev/mtd0 0 4
nandwrite  /dev/mtd0 uboot-netgear-rnd2.mtd0.kwb

I'll be back for kwboot with new u-boot.

Re: How to unbrick the Netgear Ready NAS Duo v2

For new u-boot.

Prepare the rootfs Debian-5.2.9-kirkwood-tld-1-rootfs-bodhi.tar.bz2 on USB. Note that we are going to boot with the new u-boot, so skip Step 4 (should not be done).

1. kwboot with uboot.2017.07-tld-2-rc1.readynas_duo_v2.mtd0.kwb

The u-boot log should show that there is CRC error for the envs.

2. Interrupt u-boot and,

setenv mtdparts 'mtdparts=orion_nand:0x180000@0(u-boot),0x20000@0x180000(u-bootenv),0x600000@0x200000(uImage),0x1000000@0x800000(minirootfs),0x6800000@0x1800000(jffs2)'

and then

printenv
boot

3. In Debian, check the mtds to make sure they look like this,

cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00180000 00020000 "u-boot"
mtd1: 001a0000 00020000 "u-boot-env"
mtd2: 00800000 00020000 "uImage"
mtd3: 01800000 00020000 "minirootfs"
mtd4: 06800000 00020000 "jffs2"


4. At this point, the mtd0 should be flashed with either stock u-boot or new u-boot.

If the goal is to run stock OS on NAND then flash stock u-boot.

4.1. Flashing stock u-boot

Create flash-ready uboot

dd if=u-boot-db88f6282abp_533ddr3db_nand.pached.bin of=uboot-netgear-rnd2.mtd0.kwb bs=512k conv=sync

Flash

flash_erase /dev/mtd0 0 4
nandwrite  /dev/mtd0 uboot-netgear-rnd2.mtd0.kwb

4.2 Flashing new u-boot

More needed to be verified that the new u-boot can run stock OS on NAND. If the goal is to abandon stock OS then the new u-boot can be flashed without further investigation.
