ECC errors in UBI RB2011UiAS-2HnD-IN (and solution)

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.

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?

@teppo

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

Thanks

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

@xback I can confirm they both work with the Master tree. Thanks for the help. Now if only I could write to the TFT on one of these...

Hi,

i'm trying to install openwrt to a very old RB2011LS-IN (about 8 years i guess) and i see the same ECC errors and im not able to sysupgrade to the current 19.07, 20.02 releases. it will end up in boot loop. no serial access possible, but here is the dmesg (i was not allowed to post that much characters so i have to split it).
