I see that you have the correct kernel commandline.

You should boot from ethernet using openwrt-ar71xx-mikrotik-vmlinux-initramfs-lzma.elf. If you boot this way, the mikrotik runs it's root filesystem from RAM. Then you do sysupgrade to install to flash memory. (during install, the ubi.mtd=6,2048 is also needed)

yes, i did boot from openwrt-ar71xx-mikrotik-vmlinux-initramfs-lzma.elf
when i run sysupgrade

to: rsnel: mate I have same problem (lot of ECC errors):

ubi0 warning: 0x802a2c80: error -77 (ECC error) while reading 64 bytes from PEB 311:512, read only 64 bytes, retry

any chance you would you be so kind and share that image you compiled? I'm a bit low on skills with compiling

rsnel · February 25, 2019, 8:06pm

Hi,

I have some images available at:

https://penta.snel.it/~rsnel/mikrotik/

Greetings,

Rik.

duke77 · February 25, 2019, 9:02pm

Sweet, its working :), now gonna add the rest packages...
Thanks much

rsnel · July 29, 2019, 4:00pm

Here is a patch to fix this issue in the current snapshots. Porting the patch was easy, since the snapshots are based on linux kernel 4.14.x.

https://penta.snel.it/~rsnel/mikrotik/0001-mtd-samsung-Disable-subpage-writes-on-E-die-NAND.patch

Note that, before I could sysupgrade, I had to change te contents of /tmp/sysinfo/boardname from unknown to rb-2011uias-2hnd.

xback · July 29, 2019, 4:20pm

fyi,
I pushed a fix today for Mikrotik board detection.

It think this issue will be addressed by it.

There is also a patch in 19.07 which addresses the NAND issue, but I didn't push it to master as it was flagged as source-only

Regards,

Koen

rsnel · July 29, 2019, 4:41pm

Hi Koen,

Thanks for your response. The patch from 19.07 disables subpage writes for all chips, while 'my' patch only disables subpage writes for affected chips (but the penalty for unaffected devices is very small). I'm looking forward to the new release.

Greetings,

Rik.

feitnomore · August 10, 2019, 9:42pm

@rsnel, I've installed the openwrt 19 from your images here (the 18 version doesn't work here).
Everything is going fine so far, however I'm having a hard time here with OpenVPN (kmod-tun package).
The installed version of package *kernel* is not compatible, require 4.14.125-1-a97bc8b3… while 4.14.136-1-6111847d… is installed.

Any advice? I'm only running OpenWRT on this device because of some OpenVPN functionalities.

I've tried running sysupgrade -n inside it, to the 18.06.4 image, but it doesn't work, the router keeps getting kernel panic and rebooting.

Thanks,
Marcelo

rsnel · August 11, 2019, 8:50am

Hi Marcelo,

Ik have added kmod-tun to my build. Please try to install:

https://penta.snel.it/~rsnel/mikrotik/pre-19.x-kernel-4.14/kmod-tun_4.14.136-1_mips_24kc.ipk

Note that current git master does not need additional patches anymore. The maintainer added the ECC fix! So you can build your own images following this guide:

https://openwrt.org/docs/guide-developer/quickstart-build-images

Greetings,

Rik.

feitnomore · August 11, 2019, 12:24pm

@rsnel, thanks for sharing. If you don't mind, I wanted to ask a few more questions before proceeding as I think I need to decide wether to compile my own version or not.

1 - What is the difference between your pre-18 and your pre-19? I am trying to figure here, why your pre-19 works and why your pre-18 doesn't work. Objective here is to understand if a custom built one at home from git master will work on my device.

2 - The problem that I see in keeping using your pre-19, is that if I need more kernel drivers, I'm screewed and will need to keep bothering you to provide me the packages. If I build my own custom from the git master, will it be able to use packages for kernel drivers from OpenWRT archives/downloads, or will I have to maintain a local repository with those packages? By following the link you've pointed on building the image, will I have all the packages for the modules built? I don't see any mention on the ipks generated... only elf and sysupgrade-bin.

3 - Can you share your config file for pre-19 so that I can use it on git master to build my image? This way I am trying to prevent any possible issues with my configuration once I am sure your pre-19 works. Will this config work on the git master?

Thanks, and sorry for 2 thousand questions.
Marcelo

rsnel · August 11, 2019, 7:29pm

Hi Marcelo,

pre-0.18 is git master from about a year ago (when I started this topic), it has kernel boot parameters to make it work on my router, I don't know why it wouldn't work on your device, I used it for a year
yes, ipk's will also be generated, mine appear in /targets/ar71xx/mikrotik/packages
I have published the configfile I used at https://penta.snel.it/~rsnel/mikrotik/pre-19.x-kernel-4.14/dotconfig

I hope openwrt will start publishing official images for our hardware again (the images from june dont have the ECC fix)

Greetings,

Rik.

feitnomore · August 11, 2019, 7:50pm

I will try to build it here... will let you know... I think I got some ideas.

actually, I was on Breaking Barrier before, and it had to be custom built also, because of the 0x600000 patch...

xback · August 11, 2019, 7:56pm

@rsnel

Hi Rik,

At the core of this issue, you are absolutely correct.
The problem is that Mikrotik has the habit to use other chips suddenly withour prior notice or even detectable in a product version string or so.

So your fix is spot-on today .. but could cause issues on another identical device (but with another flash chip) tomorrow.

Hence the choice for the bazooka-fix.

Regards,

Koen

rsnel · August 11, 2019, 8:11pm

Hi Koen,

Good point. I'm happy this issue and other past issues (like the broken gigabit switch) are fixed in git. Keep up the good work!

Greetings,

Rik.

teppo · August 12, 2019, 10:00pm

I have two RB2011, one RB2011il-RM, the other RB2011UiAS-RM. They both have the samsung flash mentioned in the first post, and yet neither of them work with the example images. I have watched the UART of one and it is identical to what @PisemNet is seeing.

Is there somewhere I should specify the ubi.mtd=6,2048 for these images?

xback · August 12, 2019, 10:16pm

@teppo

Do they work when compiling the latest Master tree or 19.07 branch?

Thanks

feitnomore · August 13, 2019, 12:08am

Worked Rik!
Got a bit confused because luci was missing, but I could download it from download.openwrt.org.
I've setup a local repository with packages on bin/target/.
I've noticed 2 strange things here:
1 - LuCi is not working on my Firefox Browser anymore. I enter login information and it comes back to login screen. Safari works fine, not sure if its something related to cache or cookies/offline content, will try those later.
2 - I've tried installing ddns-luci app and it broke my LuCi. I don't have the error right now, but it throws some LUA errors when opening LuCi, stating something about a missing package, however I haven't found it.

Thanks,
Marcelo
