This is promising. I will rebuild initramfs without LuCI, so you can try to flash.
You'll need to erase and run ubiformat, because minimum write size changed (as I wanted to).

Edit @g6094199, please try once more. I've rebuilt the initramfs.
While at that, I adapter AR8327 LED support to use color/function properties. So another little step further to getting this supported properly.

I think my fix changed something - but didn't actually disable subpage writes.

I'm thinking about picking up that NAND at Aliexpress - I guess a double-check is needed if my patch is correct - it's in this branch:

Edit: I found the older patch: https://penta.snel.it/~rsnel/mikrotik/0001-mtd-samsung-Disable-subpage-writes-on-E-die-NAND.patch - only just now. I'll try to integrate it soon. And perhaps upstream it to LKML.

Also, some interesting discoveries w.r.t to LCD and touchscreen there. I identified the touchscreen controller chip as well - but again, its auxiliary GPIOs are unknown. It's Zilltek ZT2046Q, which seems to be a clone of TI ADS2046.

I haven't managed to extract the LCD panel from it's mount yet, the space there is very tight. Does anyone has its markings, hidden under that black plastic?

Another day, another firmware to test.
@g6094199 do you recall, that @rsnel's fix from here: ECC errors in UBI RB2011UiAS-2HnD-IN (and solution) - #5 by PisemNet worked for you in the past? I cherry picked it - merged without any conflicts, and built the test firmware, dropping my previous attempt.
Build is in the same location again, in case you'd like to test it.

I've got RB2011UiAS-2HnD-IN, so if help is needed I can test new builds.
I saw Leo-PL submitted a PR but then it was closed so does that mean that there is a snapshot?

172

The pull request https://github.com/openwrt/openwrt/pull/17617 still appears to be open.

173

Leo-PL marked this pull request as ready for review last week

I don't have SFP's lying around. So I can't test that.

AFAI can figure out, i'm with the 128 samsung nand. Which should be working.

I'll figure out how to build this particular PR and if I can - test it.

174

I built @Leo-PL 's pull request and tried to install openwrt-ath79-mikrotik-mikrotik_routerboard-2011uias-2hnd-squashfs-sysupgrade.bin, but:

Keep settings and retain the current configuration?

Please wipe config during upgrade (force required) or reinstall. Reason: NAND images switched to yafut. If running older image, reinstall from initramfs. Invalid sysupgrade file. Image check failed.

The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform.

 Force upgrade

Select 'Force upgrade' to flash the image even if the image format check fails. Use only if you are sure that the firmware is correct and meant for your device!

It seems my device is supported, by image is 1.1, device is 1.0. I don't know what that means and whether it's save to continue.

175

I also tried the openwrt-ath79-mikrotik-mikrotik_routerboard-2011uias-2hnd-squashfs-sysupgrade.bin from the same pull request, but still:

image
image1047×760 105 KB

I'll wait until someone confirms I can flash either the initramfs or the sysupgrade image and if yes - which one of those.

176

if you are comming from an 19.07 install or similar upgrading might brick you device.

best is to tftp boot the initramfs and then flash the sysupgrade.

177

I probably forgot to set the compat_version in uci_defaults in one of older builds.
I can't guarantee upgrade from ar71xx at this time either - I had quite a busy time recently.

178

yes, from OpenWrt 19.07.10 r11427-9ce6aa9d8d / LuCI openwrt-19.07 branch git-22.099.58928-786ebc9.

upgrading might brick you device

Documentation says that "The MikroTik bootloader is preserved even after OpenWrt is installed into NAND or NOR flash. " - this means I can always unbrick a routerboard?

Documentation says several things:

Since an initramfs image is just a temporary image (only loaded into RAM), it is safe to test a particular version of OpenWrt by netbooting (using DHCP/BOOTP/TFTP) and downloading the initramfs image.

@g6094199, I guess you were saying just that.

# cat /sys/firmware/mikrotik/hard_config/booter_version
6.47.10

I managed to boot from BOOTP /TFTP, following the instructions:

Later it said:

dnsmasq-dhcp: 182527990 vendor class: udhcp 1.37.0
dnsmasq-dhcp: 182527990 client provides name: OpenWrt

Which means it booted. After that I connected to a lan port, got an IP, but that was it - no ping, no ssh, no nothing, nmap returns nothing.

Later i tried it again and same result. Even before disconnecting the wan port I tried to scan it with nmap - I got nothing.

While booting it gets 192.168.1.161, then after it boots it presents itself as Openwrt:

dnsmasq-dhcp: 1843128298 client provides name: OpenWrt

dnsmasq-dhcp: 1843128298 bootfile name: openwrt-ath79-mikrotik-mikrotik_routerboard-2011uias-2hnd-initramfs-kernel.bin

Yet, nothing works on the wan - ping shouldn't work, because by default it's disabled.
It responds to arp requests:

Also some dhcp:

Even dhcpv6:

So it seems it booted successfully, but I can't get inside.

Second time I connected on a lan port I started sniffing immediately:

while pinging I don't see the icmp requests I just see arp requests (first to the router, then broadcast, no responses):

Also, some ipv6 stuff:

Ideas?

I realized, that my previous patch was completely wrong. I made a new one, tailored to our problematic NAND. Please try booting initramfs, and check MTD files as previously - don't install yet, because it'll probably OOM again.
