I mistakenly bought TP-Link WR841N, since there are nightly builds e.g. here https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2020/11-15-2020-r44809/tplink_tl-wr841ndv12/ However sadly the ones I bought are hardware v14, which according to the "other" firmware guys (https://openwrt.org/toh/tp-link/tl-wr841nd) it is MediaTek based, MT7628NN SOC and MT7628NN (built in) wifi chip. AND is only 4 MB flash, 32 MB RAM.

Assuming I am willing to compile myself, strip out certain features, is this at all doable, or completely hopeless?

Are there newer build notes than the ones I'm finding here? https://wiki.dd-wrt.com/wiki/index.php/Development#Building_DD-WRT_from_Source that seems to mention comments like "as of 2010 the download size was...", etc, which does not instill confidence.

And if it goes well, where do I share my build configs and get it into the nightly beta builds?

okay first question, this page https://wiki.dd-wrt.com/wiki/index.php/Ddwrt_selective_co.sh script seems to work (I get about 16 MB under redboot/, 648 MB under ar5315_microredboot/, 3.6 GB under src/, and 4.1 GB under .svn).

But after that download, it say says (since I only want to build for my own hardware, not every target), to cd to src/linux/<target-linux> and run:

svn up --set-depth infinity

However in what the script downloaded so far, I only have
[pre]
src/linux/adm5120/
src/linux/brcm/
src/linux/sl2312/
src/linux/universal/
[/pre]

How do I know which of these to go into for my (MT7628NN) hardware? I guess since it doesn't seem to match any of the other three (adm5120, brcm, sl2312) that I should cd to universal and do the svn command from there? -Cheers/Thanks
