<neggles>
slh: oh jeez are people still really trying to make 4/16 work
<neggles>
and here i am considering buying a 512mbit SDRAM to put on this little board... it's a waste of money probably but
<slh>
sadly requests like that come in somewhere between weekly and every second week - and those users are very persistent in their requests (but not in actually putting in the work)
<Namidairo>
are any of them saying "I'm disappointed in you"
<slh>
and I really don't get the "security doesn't matter" approach of assuming 10.03 and friends to be an option - for anything at all
<slh>
yes, regularly
<neggles>
if you have a 4/16 device you have two options, and only one real option: run 19.07 or older, or e-waste the thing
<Namidairo>
i saw one in the ax3600 thread and almost spit out my coffee
<neggles>
you can probably guess what my opinion of what you should do is.
<Namidairo>
option 3: learn how to do bga rework
<neggles>
oh i suppose there's the third option of "replace the flash chip and maybe RAM", which I *have* done once or twice
<neggles>
"bga"
<neggles>
4/16 devices are going to be CFI/SPI NOR and SDRAM/DDR1 in TSOP-II :P
<Namidairo>
but they have to learn the pain of putting the solder balls into the template
<slh>
I did understand replacing flash/ RAM in the early days, maybe until ~2012/ 2013 (as 32 MB RAM were the top of the world)
<neggles>
ah, i mean they will not have bga ram/flash
<neggles>
if you've got bga parallel NOR, well, bad luck
<Namidairo>
yeah they probably won't
<slh>
these days not really, as you can get better spec'ed devices for 'reasonable' money
<neggles>
TSOP-II-54 SDRAM is actually pretty easy to replace but
<neggles>
cheapest i can find is about $4-5 for a 64MB single-chip
<neggles>
and you have to buy five to get that price
<slh>
o.k., replacing 8/ 16 pin spi-nor flash is one thing, RAM (even the ancient 2005 vintage stuff), not really
<Namidairo>
and with the time needed to research and do it you might as well just buy a $40 device that's supported
<neggles>
i did it yesterday!
<slh>
(at least not unless you happen to own reflow stuff already)
<neggles>
hot air pencils aren't that expensive :P
<neggles>
but yes, i was about to say, $25 buys a lot of devices that are at least 8/32 or 8/64
<Namidairo>
128/128 is in the $40 range right
<slh>
more expensive than the markup for a better router (at a quantity of 1-2)
<neggles>
yeah
<neggles>
~$80 for an 858D is money well spent if you're screwing around with routers on the reg but
<neggles>
throw the 4/16 device in the trash where it belongs, unless it's some weirdo hyper-custom thing for a specific device that you can't replace, in which case... put the newest release you can on it and connect a better router in front of the thing?
<neggles>
for bonus points, put just the kernel in the flash, then mount rootfs over nfs from the other router :P
<neggles>
if that sounds too complicated / not worth doing, well, I guess the device wasn't so irreplaceable after all...
<neggles>
I'm all for keeping old hardware alive, but a 10-15+ year old <$50 router that wasn't anything to write home about when it was new? nah...

even quite 'entitled' requests for 2/8 devices are coming in semi-regularly (thank you, mt7628kn)
<neggles>
O_O
<neggles>
i opened up one of those xiaomi usb stick wifi extenders and found one of those inside it
<neggles>
immediately concluded it was never going to run anything other than the eCOS it came with and tossed it
<PaulFertser>
I'd like to get wrt54g working with 32 MiB RAM so that dumb AP WPA3 performance could be benchmarked.
<neggles>
i believe I still have my WRT54GL v1.0
<neggles>
...somewhere
<PaulFertser>
I tested it recently and it still boots master but 16 MiB isn't enough even for a dumb AP.
<PaulFertser>
Enough for an ssh managed switch though.
<neggles>
yeah
<neggles>
i should try flipping some switches on the kernel build for this vocore, see if i can get another MB or two free
<neggles>
oh the WRT54G/GL are just a TSOP-II-54 SDRAM
<neggles>
32MB chip for those is about $3 shipped and i have a couple here somewhere
<neggles>
will the radio even *do* WPA3?

neggles: yes
<neggles>
wow
<neggles>
software crypto though
<PaulFertser>
neggles: the chip is 3.3 V VDDQ though, so probably those you have are not exactly suitable.
<neggles>
they are indeed
<PaulFertser>
Eh, 3.3 V VDD, 2.5 V VDDQ
<PaulFertser>
I tried one I desoldered from dir-615-e4 and it doesn't work :(
<neggles>
hmm, split rail eh
<neggles>
most SDRAM is 3.3V or 2.5V on both
<PaulFertser>
Yes, the one I had is 2.5 V on both.
<neggles>
ah
<neggles>
it might also have a diff row layout or need other init changes in the bootloader
<neggles>
do you happen to know what the original part number is
<PaulFertser>
neggles: on my wrt54g v1.1 it's HY5DV641622
<PaulFertser>
FTP-J
ecloud_ has quit [Ping timeout: 480 seconds]
<neggles>
oh that's DDR
<neggles>
interesting
<PaulFertser>
Or probably HY5DU641622FTP-J
<neggles>
TSOP-II-66
<slh>
hmm, I do still have an asus wl-500gd and wl-500gp v1 with ath5k wireless, somewhere on a shelf and not used them in quite a while...
<slh>
those are 4/32 and 8/64
<slh>
err, 4/32 and 8/32
<neggles>
12 row lines... let me check something...
<neggles>
darn the micron ones i have are 2.5V on both
<PaulFertser>
neggles: HY5DU281622FTP-J should be the exact number.
<PaulFertser>
neggles: and it's 2.5 V on both. Hm, why doesn't it work then... I tried memtesting over JTAG and that doesn't give errors.
<neggles>
ahh okay
<neggles>
um
<neggles>
what chip did you put in?
<PaulFertser>
neggles: ESMT M13S2561616A-5TG
<f00b4r0>
i have a nice little 16/32 device. Sticking to 19.07 while it remains practical :)
<neggles>
PaulFertser: right, found your problem...
<neggles>
that ESMT chip has 13 row lines and the hynix has 12
<PaulFertser>
neggles: it boots up to "No eou key find" and then hangs. I can halt it over JTAG etc.
<neggles>
are all 13 wired up?
<PaulFertser>
neggles: of course, how else would it be twice the size?

hauke: I sent a patch some days ago regarding a revert for the gl-b2200; I am waiting for Christian to answer, since in reality I would prefer a different form of his patch to be applied rather than this revert, but at the same time would like the gl-b2200 support to land in 22.x with all the 3 wi-fi devices working. What do you suggest to me to do?

I would wait for Christian

I hope he answers in the next days
<mrkiko>
hauke: how much time do we have until the 22.x final release happens?
<mrkiko>
approximately I mean - months or weeks?
<mrkiko>
I guess months
