[    7.126418] Rebooting in 1 seconds..

ilyas · February 20, 2019, 9:01pm

hi @pellmen... yeah i saw his message on 4pda ...
it's strange that he says it booted fine the first time and then started to bootloop... there's no real reason for it to do that.
can you verify that he installed the new bits properly? (or... ask him to reinstall them). if he tried to use sysupgrade (and misunderstood my installation message) that would make a mess... (sysupgrade will work after upgrading to the latest bits)

since he's in a bootloop anyhow, he might as well tftpboot (use initramfs file... and make sure you rename it or you'll have to type all that garbage in)... there are tutorials out there, but it's pretty straightforward (and i can help if he has a hard time... i'm using tftpboot/initramfs all the time now... i was getting scared of burning my nand)

once he boots with initramfs i'd be curious to see what's up with /dev/mtd9 (the ubi partition). can he verify that it starts with "UBI"?

dd if=/dev/mtd9 bs=1 count=3

should result in

UBI3+0 records in
3+0 records out

to reinstall (from tftp/initramfs boot of the latest bits):

dd if=factory.bin bs=1M count=4 | mtd write - kernel
dd if=factory.bin bs=1M skip=4 | mtd write - ubi

If that doesn't do the trick, I'm going to start to have a horrible suspicion that maybe there's something important i'm missing in the DTS file...

PeLLmEn · February 20, 2019, 9:25pm

@ilyas, can you, please, explain about initramfs-kernel.bin, factory.bin, sysupgrade.bin files? Or give a link to any faq?
As I understand, sysupgrade.bin is for upgrading firmware from web-interface of openwrt (it's not working in beta 4?); factory.bin we can use for updating from stock, and for updating existing openwrt through

mtd write factory.bin firmware

About initramfs I know nothing(

ilyas · February 20, 2019, 9:59pm

@pellmen: I'll try my best. I hope I don't botch this because I'm just figuring it out myself...

initramfs-kernel.bin is useful for tftpboot ... it's got all you need in a neat package. you just boot into it and don't worry about touching your nand. it's not what you're going to give to mtd write.

factory.bin is your friendly "write this file to mtd and reboot" file. obviously if something goes wrong you won't be able to boot (and then back to tftpboot).

sysupgrade.bin has the kernel and all your other files together, but you're not going to 'mtd write' that, but you're going to feed it to sysupgrade (the command... i suppose luci also can do it). sysupgrade is nice because it installs the new (upgrade) system but keeps your configuration files (etc) around.

IIRC sysupgrade was broken in 'beta 4'. trying to use it resulted in something very similar to what you reported (similar bootloop failing to find root filesystem). I've come to the conclusion that that was because of the partition layout I was using (ie, if the kernel grew the UBI partition would get clobbered).

sysupgrade works now (I've used it many times).

mtd write factory.bin firmware is what you want to use if you're running (the infamous) 'beta 4'. If you're coming from stock you need to split factory.bin so it spans two partitions (kernel1 and rootfs0):

dd if=factory.bin bs=1M count=4 | mtd write - kernel1
dd if=factory.bin bs=1M skip=4 | mtd write - rootfs0

(come to think of it, it wouldn't hurt to blow away the other (remaining) partitions either:

mtd erase rootfs1
mtd erase overlay

If for reason (like our friend with the bootloop problem) you've already installed my latest (rc1) and just want to re-flash it (and don't want to use sysupgrade for whatever reason) you'll need to do

dd if=factory.bin bs=1M count=4 | mtd write - kernel
dd if=factory.bin bs=1M skip=4 | mtd write - ubi

(since "firmware" as a partition no longer exists in rc1). Or (if you're not bootlooping) you can just do

sysupgrade sysupgrade.bin

I don't know if this helped...

ilyas · February 20, 2019, 10:18pm

EDIT: also ask him to verify that the files are being written properly (using 'mtd verify')

@pellmen one more thought about your friend with the bootloop... depending on how courageous he's feeling, I would suggest he could blow away kernel0 (aka "kernel_stock") and put openwrt there. Advise him to backup kernel0 (so he can re-flash it later if he needs to... I think it's helpful to have).

I haven't tried this myself, but since he has his bad block in "kernel" (ie, formerly kernel1, after 0x600000) I think we might be able to narrow down the problem (ie, is it really because of bad blocks?) if (just in his case) we put the first part of factory.bin in "kernel_stock" (formerly kernel0) and the rest of it in ubi.

In other words (from stock):

nvram set flag_try_sys1_failed=0
nvram set flag_try_sys2_failed=1
nvram set flag_boot_success=0
nvram commit
dd if=factory.bin bs=1M count=4 | mtd write - kernel0
mtd erase kernel1
dd if=factory.bin bs=1M skip=4 | mtd write - rootfs0
mtd erase rootfs1
mtd erase overlay
reboot

There was something I read about uboot looking for a xiaomi-signed kernel file so I'm not sure this will work. Make sure he backs up rootfs0 first and knows how to use tftpboot (because he might need it ;))

Only for the adventurous... (no, I don't think you can hard-brick your router unless you screw up the uboot partition, but we're not touching that. So you should be able to recover with tftpboot).

ilyas · February 20, 2019, 11:33pm

BTW, for those who are planning on putting my bits into "production": I can get it to panic by concurrently copying a bunch of very large files over wifi (both 2.4ghz and 5ghz)... the same over ethernet is fine. I seriously hope MTK fixed that in later versions of their drivers...

Charleslcso · February 25, 2019, 2:23am

Guys, thanks for the great work!

From all the conversations above, does it mean that all brands and models using MT7621 will crash/hang/corrupt large files after transfer?

https://wikidevi.com/wiki/MediaTek_MT7621

This Xiaomi router is out in 2017, do you guys think something else using a newer chipset is more ideal?

PeLLmEn · February 25, 2019, 4:59am

I've already get panic for large file download.

kevinracer · February 27, 2019, 4:39am

Can someone confirm OpenWRT on R3P work with VHT160Mhz? Stock Firmware cannot change bandwidth.

ilyas · February 27, 2019, 6:04am

@kevinracer ... there's an easy way to find out

ilyas · February 27, 2019, 6:08am

@Charleslcso i'm fairly sure the problem isn't with mt7621 (which is the SoC)... most likely it isn't with the mt7615 (the wifi chip) either... it might be the driver or it might be the driver configuration (most likely the latter). we're doing something rather unorthodox with the wifi driver (that is, using binary modules compiled with unknown settings, most likely for DBDC mode) and trying to hack it to get it to work... so the short answer is 'i don't think (at all) that it's a hardware problem'...

ilyas · February 27, 2019, 6:12am

@pelllmen how did it go compiling the wifi driver from source? i tried over the weekend but the instructions (on the page you linked to) don't seem to make sense or fit the code i've downloaded (for example, no "patches", but it talks about patches).... also the convoluted way he describes to get it to compile (at least, configure) makes me think that that can't really be the proper way of doing things... with the earlier (2016) sdk, mt7615 is a "package" which makes sense... except that uses an older driver (4.4.0.2 or something), so the patches don't all fit (and the newer driver might need other patches).

btw, did you notice (from @lukasz92 's answer on the mt7615 thread) that mt76 apparently already has some kind of support for mt7615?! incredible!

btw2, messing with the driver source, i'm pretty sure @nossiac's binary modules are compiled for DBDC mode (one chip with two frequencies) like the K2P has... I'm hoping recompiling without DBDC mode will result in something saner.

PeLLmEn · February 27, 2019, 6:37am

@ilyas, my friend is trying to repair the system of compiling - he said it's broken. He said, that getting working driver can take a week or more becase he can watch it only a few hours in evening.

ilyas · February 27, 2019, 3:40pm

@pellmen tell your friend not to spend too much time on it.. it's annoying. i got the source for version 5.0.2.0 to compile ... @nossiac uses 4.4.1.2 (iinm)... the "latest" may be a good or a bad thing (honestly I was just playing around and tried to compile every version i could find... this is the first I could compile)... I'll try with 4.4.1.2 (etc) later.

BTW, i get the impression that this code hasn't really been tested for non-DBDC mode (as in... it was missing some #ifdef's to guard for non-DBDC mode)... once I get it into a "package" format I'll post it in case anyone wants to play around (and yes I'll post the build instructions and patches too... of course...)

EDIT: OK, mt7615e (closed-source) version 5.0.2.0 compiles... could connect via 5G at first try (ssh). 2.4ghz seems like it needs some configuration options changed. source/patches will be posted as soon as it's looking sane (and a little more polished)

EDIT2: OK, it was just a silly configuration file slip that was causing wierdness with 2.4ghz. I can connect to the router (and get an IP address, etc) over both 5ghz and 2.4ghz...

EDIT3: @pellmen i've had the new kernel modules running all night doing simultaneous iperf3 and large file (~2GB) copy over ssh.... no kernel panics. can't say i'm much impressed by the speed, though (~70-80mbps for 5ghz; 40-50 for 2.4ghz)... although i honestly haven't compared it with @nossiac's binaries. want to try?

PeLLmEn · February 28, 2019, 8:54am

Yes, of course)

I'm up for testing if you guys need me to. Its very liberating to get rid of the eavesdropping MI router firmware.

@ilyas can you share your firmware

Thanks for RC1. It works, but tell me please how install l2tp vpn server on it? I try to install packet and its says The installed version of package kernel is not compatible, require 4.14.103-1-eb8ed4b9… while 4.14.93-1-1c5c2146… is installed.
Help please!

ilyas · March 1, 2019, 6:11am

@pjgowtham i'm not sure what you mean when you say "can you share your firmware".... i posted all of the source (same place where you downloaded the binaries from... or scroll up in this forum).

as for samba share and l2tp (@splash)... at the moment we're stuck at kernel build 93 (which is the latest that we have prebuilt mt7615 modules for). as i've posted earlier, i now have compiled and (what appears to be) working kernel modules of my own (so we're no longer stuck with the prebuilt modules, and we can sync to the latest openwrt/kernel). i suppose there are two options (and related sub-options):

for people who prefer to stick with the tried-and-true prebuilt modules (that is, mt7615 version 4.4.1.2), i suppose the easiest way would be to download the openwrt source and build it themselves (choosing whatever packages they want) and then add in the kernel modules. i do realize it's a hassle for windows-users (presumably need to install vmware, etc etc... and if you're not familiar with linux/unix at all, it might be daunting). so i don't mind building/posting packages, although i would rather not build every single possible package and upload all of them.... maybe if people give me a list of packages they want, i'll build and post them.
for people who would like to use bleeding-edge latest (possibly better, maybe worse... unknown) mt7615 version 5.0.2.0 modules that i've managed to compile, once i've posted the new binaries, you should just be able to use the regular openwrt packages (ie, kernel 103 or whatever the latest and greatest linux version is).

perhaps i'll take a moment for a personal rant: i really don't see why the patches needed to compile the mt7615 (or other "leaked") sources aren't (currently) publicly available... the "the source isn't free to distribute" argument is weak: you're not posting copyrighted source, you're posting a patch... there's no intellectual property involved. it's almost as if people are trying to create personal dependencies and carve out little niches of "i can do something you can't" for themselves to make themselves special...

anyway, i'll be posting the patches and build instructions... the world has too many private niches. and i'm already special
