Build is failing

[krishgcek]

I am trying to build for tplink 845n . But build is failing, with error images are too big,

Log link :https://github.com/krishgcek/padavan-builder-workflow/suites/26120389697/logs?attempt=1

This error means that built firmware size is too big for the target device (TP-LINK TL-WR845N v3 only has 4 MB flash iirc), so you need to cut down included apps or themes to reduce firmware size.

UPD: skimmed through your log and it actually looks like builder can't find firmware it had just built... will look into it later

Can you please tell me what else I can disable?

Here's where images are too big error comes from: https://gitlab.com/hadzhioglu/padavan-ng/-/blob/master/trunk/tools/mktplinkfw/mktplinkfw2.c#L290 — it checks if device flash has enough space for kernel + root filesystem. Looks like even with minimal config you get ~0.86 MB kernel + 3.55 MB root fs, which is too big for 4 MB flash you device has. I'm not sure if 4 MB flash devices are still supported by Sergei's Padavan repo, you better ask there: https://gitlab.com/hadzhioglu/padavan-ng/-/issues

I found an alternative repo which is a bit old,

https://gitlab.com/dm38/padavan-ng/-/tree/master
I couldn't run your script as the toolchain is new. Can you please provide me an older version of tools chain to configured in variables?

@krishgcek this builder can be used with dm38 repo with minimal changes via pre-build.sh, see https://4pda.to/forum/index.php?showtopic=714487&view=findpost&p=125916717 (Russian, use online translator if needed, feel free to ask questions 😉 )

I was able to compile it. But after flashing the 3 leds of the router was flashing sequentially. So something is wrong with booting. I was using tftp method.
