The supported hardware page lists 10.03.1 as current release for WRT54G 3.0

wiki.openwrt.org/toh/start?dataflt%5BModel*%7E%5D=WRT54G

But both ChaosCalmer and LEDE

archive.openwrt.org/chaos_calmer/15.05.1/brcm47xx/legacy/
downloads.openwrt.org/releases/17.01.4/targets/brcm47xx/legacy/

have linksys-wrt54g-squashfs.bin downloadable.

Are these newer builds above not validated (or known to be broken)?

PS Sorry no links were allowed.

Thanks

Newer build not recommended due to the device having only 16 MB of RAM.  The newer kernels and builds require at least 32 MB.

Thank you @mk24 So could one limit number of connections (or other pools) to make the 16 MB workable?

Support for devices with only 16 MB RAM has officially been discontinued with Attitude Adjustment 12.09 (even 32 MB RAM is very borderline today), although that formal declaration only happened after the fact that this little amount of RAM was posing serious problems before already. While it is still possible to create a very targetted and stripped down build for 4/16 devices today, using current LEDE master, the results are definately not a full-featured firmware (luci is definately not possible, but it doesn't stop there) and still hitting out of memory conditions (or more colloquial, crashes and freezes) left and right.

While reverting to older firmware builds is technically possible, their security status precludes this from being a serious option (8+ years of known and unfixed/ unfixable security bugs, including remote ones), at some point it's no longer sensible to use 14 years old devices with very limiting system specifications. See https://lede-project.org/meta/infobox/432_warning for a more detailed explanation.

Thank you for the pointer @slh

The page brings up the possibility of generating images of various sizes. Might this be similar to the DD-WRT approach? mini/micro/std/etc.

ftp://ftp.dd-wrt.com/betas/2017/12-29-2 … /broadcom/

Wouldn't those be corrected by firmware fixes?

Thanks

1) No.

2) Yes, the fixes are in LEDE 17.01.x/ OpenWrt master - but not in any earlier version, those haven't been touched since their release. The problem just is that your 14-year-old 16 MB RAM device doesn't meet minimum system requirements (>32 MB RAM) for current (>2010)/ fixed firmware images anymore and would just crash and burn if you tried a release build.
