05:53 <philipp64> tmn505: usually when I do this sort of work I have development models of the platform with JTAG's or serial ports soldered on...

05:55 <PaulFertser> philipp64: it doesn't take a development version to attach serial console (not rs-232 though)

05:56 <philipp64> Okay, so how do I get a console onto an Archer A7 v5?

05:56 <PaulFertser> philipp64: in your initial question it's unclear who/what gets the image. Are you following the instructions in the commit message?

05:57 <philipp64> sorry, which commit message?

05:57 <PaulFertser> philipp64: https://openwrt.org/toh/tp-link/archer_a7_v5 talks about serial

05:58 <PaulFertser> philipp64: commit message of the commit which added support for this board.

05:58 csrf has quit [Quit: ZNC 1.7.2+deb3 - https://znc.in]

05:58 <PaulFertser> philipp64: it clearly tells what to do.

05:59 <philipp64> I take the -sysupgrade-factory.bin image and copy it to /tftpboot/ArcherC7v5_tp_recovery.bin and then follow the steps here: https://openwrt.org/toh/tp-link/archer_a7_v5#installation_using_the_tftp_method

05:59 csrf has joined #openwrt-devel

06:01 <PaulFertser> philipp64: that sounds about right, but what exactly happens is unclear without serial output

06:02 <philipp64> this commit? 1e4ee63cc8d1889a78b539a5ed7be8d56e9b976f

06:02 <philipp64> reading it now...

06:03 <philipp64> Not sure what's meant by "Make sure you have shorten R24 on the PCB" here: https://openwrt.org/toh/tp-link/archer_a7_v5#serial

06:04 <PaulFertser> philipp64: it refers to some part of C7 instructions

06:05 <PaulFertser> Appalently there's a placeholder for resistor with R24 designator and it should be shorted.

06:06 ivanich has joined #openwrt-devel

06:07 <PaulFertser> philipp64: size of the image that you mention sounds wrong.

06:08 <PaulFertser> philipp64: https://downloads.openwrt.org/releases/21.02.0-rc1/targets/ath79/generic/openwrt-21.02.0-rc1-ath79-generic-tplink_archer-a7-v5-squashfs-factory.bin is about 5.5 MB

06:08 <philipp64> I might be tired, but I'm looking at https://openwrt.org/toh/tp-link/archer_c7#version_50 and can't tell what's supposed to happen.

06:09 <philipp64> sorry, image was 12.9MB... dropped a decimal point.

06:10 <PaulFertser> philipp64: that's still odd

06:10 <PaulFertser> philipp64: is that something you self-compiled?

06:17 feriman has joined #openwrt-devel

06:17 <philipp64> yes. I've enabled strace, gdb, valgrind... I need to debug some management software under development.

06:22 dansan has joined #openwrt-devel

06:35 <PaulFertser> philipp64: I suggest you try to flash the factory image built by the buildbots

06:35 <PaulFertser> philipp64: then if it works you can sysupgrade to your own

06:59 <PaulFertser> philipp64: it's possible that u-boot is using a severely limited memory region when fetching from tftp so the size might be essential there

06:59 <philipp64> hmm... no, seems to have been something else.

07:00 <philipp64> OutBackDingo sent me a .config that I substituted in and it booted better, so I probably had a kmod that was causing the build to fail...

07:00 <OutBackDingo> YAY!

07:03 <PaulFertser> philipp64: but are you able to boot vanilla upstream OpenWrt image?

07:05 <PaulFertser> philipp64: additional kmods are loaded after pre-init so you should be able to enter generic failsafe even if such a bad kmod is present.

07:05 <PaulFertser> philipp64: I'm asking about vanilla image because it's essential for the upcoming release. If the factory image from it doesn't work it should better be fixed during the RC stage.

07:06 <philipp64> PaulFertser: it might also be some other reason, like me having bad CONFIG_KERNEL_* settings...

07:07 <PaulFertser> philipp64: regarding the serial, apparently the board has some resistor divider meant to be used on Rx line, and it's not present so it's probably enough to simply short R24 with a blob of solder. Should be fairly obvious by looking at the board when you have it in your hands.

07:07 <philipp64> but to answer you, I had been running https://downloads.openwrt.org/snapshots/targets/ath79/generic/openwrt-ath79-generic-tplink_archer-a7-v5-squashfs-factory.bin just fine.

07:08 <PaulFertser> philipp64: ok, that's good to know. So you have a solid recovery path now no matter what.

07:08 <philipp64> Yup.

07:15 <philipp64> PaulFertser: thanks for the pointers.

07:23 feriman has quit [Ping timeout: 240 seconds]

07:25 <PaulFertser> philipp64: best of luck with your debugging. BTW, do you know OpenWrt has a convenient script to use gdbserver so in cases where valgrind is not needed you might benefit from that. Also valgrind can be used as a gdbserver too.

07:26 <philipp64> did not know that, no...

07:26 <philipp64> Do I need vgdb?

07:27 <PaulFertser> philipp64: it's integrated in valgrind, you can just run it in a way so that it stops on the first error, then you attach gdb from your host, the OpenWrt script gives you all the sources and debug info etc.

07:28 <PaulFertser> philipp64: so basically you can add gdbserver even to the very constrained targets and then debug whatever you need by running gdb on host, nothing special needed, no flash space on target wasted (in case you just need debugging and not valgrind).

10:01 <rsalvate_> ldir: I'm going to start tagging you in my bump pulls, otherwise it's duplicated work. :) https://github.com/openwrt/openwrt/pull/4123

10:02 rsalvate_ is now known as rsalvaterra

10:05 <ldir> rsalvaterra: fair enough - I was just looking at pushing 'my' bump when you posted that - you can be bothered with commit messages...I was lazy and hadn't done that yet :-)

10:05 <rsalvaterra> ldir: Oh, this is weird. I got confused.

10:06 <ldir> ???

10:06 <rsalvaterra> I thought you and also done the bump, since in your tree it shows you as the author.

10:06 MichaelOF has joined #openwrt-devel

10:07 <ldir> yes I had, but not yet pushed to master... I was thinking about pushing to master and coming up with a suitable commit message when you irc'd me :-)

10:07 <rsalvaterra> And sometimes it shows me as the commiter, which is impossible, thankfully. :P

10:07 <ldir> so because I'm lazy I pulled in your PR (github-apply.sh) and pushed that instead :-)

10:08 <rsalvaterra> Ah, I see. :)

10:09 <ldir> surprising to see a bump with no refresh changes though

10:10 <ldir> does happen, just not very often

10:10 <rsalvaterra> ldir: Indeed, I had to double check, but such is life.

10:10 <rsalvaterra> Not many changes… https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/?h=linux-5.10.y

10:12 <rsalvaterra> I was now looking at https://git.openwrt.org/?p=openwrt/staging/ldir.git;a=commitdiff;h=a42bc0f9d88e50f8f16e24c07f0b0284d92fd444

15:44 <nick[m]1> aparcar: could we maybe also backport that into 21.02? Othewise the gluon community will not benefit from the SoC. We plan to role out more free wifi in public spaces, since corona... I think this SoC is very good for that (except if there is a window). I would make a PR, or do you think it will be rejected?

15:55 <aparcar[m]> well then I don't know - sorry... I don't want to postpone the 21 release any more

15:57 <nick[m]1> no problem. it is just a small change. Let me try. ;) thanks for helping.
