How can i get an image for Netgear router Jwnr2010V5 N300 router. It has 4 MB memory and 32 MB flash. it runs on RAlink processor
https://openwrt.org/supported_devices/432_warning
https://openwrt.org/toh/start?dataflt[Model*~]=2010 -- not supported
You could port it yourself, but I wouldn't hold my breath for someone to do it for you. Significantly better units with current wireless chips and sufficient resources to support current, secure firmware (at least 16 MB of flash and at least 128 MB of RAM) start at under US$20.
SoC: Mediatek MT7620N
Flash: 4MB
RAM: 32MB
I know 4MB is not ideal but can I build a firmware within 4MB ?

This is what I have done so far https://github.com/shibajee/openwrt/commit/d697db81d691a178bc30e8566f196d6e1adf20f9
I'm so close but getting this error and can't figure out what to do. This error goes on for 2~3 min and then system reboots.

This is the oem bootlog if anyone want https://gist.github.com/shibajee/8fb5bd3fd422a8957a3de3f7352eed45
Hi, can anyone solve my problem ? I'm so close getting this.
you can see that something wrong with squashfs.
rootfs_data partition (read/write part of rootfs) is not created. So jffs2 filesystems creation fail.
You ignore 4/32 warining but I think that your firmawre is too big.
Ya, when I unzip the .img file kernel+rootfs was bigger than 0x3c0000 (firmware partition)..tnx for reply
can you tell me what is the easiest way to figure out GPIO no. that controls leds and reset button ? there is no detail documentation for the device or writings in PCB @123serge123
Was gonna ask you if you got this fixed, but saw your question.
You can build a great image if you use 18.6.8, but 19.7 is stretching it... Here's what I have in my 4MB (really 3,5MB) MR3020 build. Since the Jwnr2000 isn't a travelrouter I probably wouldnt include USB support and instead would switch it out with banip/vpn policy routing/Ipv6 or something.
Apps:
Travelmate
SQM QoS
Upnpd
Firewall
Wake on LAN
uHTTPd
Time Synchronisation
Custom Commands
Wifi Schedule
Dynapoint
WLAN Blinker
Modules:
ATH9-USB
rtl8150
rtl8152
kmod-usb-net-asix
kmod-usb-net-asix-ax88179
Wireguard
Relayd
But yeah, be sure to chime in if you can get the Jwnr2010v5 to work. Was just given one for free and it will make a great gift to someone with Openwrt 18.6.8 with a good set of features.
Almost done, device is up and running, just doing some final checking on some gpio leds config. But the problem is I kinda backport the necessary tools to lede-17.01 branch (kernel 4.4). On 19.07 branch or master (kernel 4.14/5.4) image size gone over 3.8MB, this is without luci and even if I disable some kernel options like dump core/crash dumps it's still over 3.8MB on master, 19.07 barely fits and u can't install anything..my last resort will be 18.06.
18.06 is a good compromise, but tbh I’m good with 17 too even though it’s less secure. In all practicality it’s probably just as secure. It’s not like some hard core hackers are gonna pull up on my driveway and hack my wifi anytime soon..
I sent PR and official support added git commit. LuCI won't fit, disable some options to compile it, follow this.
Also backported it to 18.06 branch, here is the source and compiled image also uploaded in release section with luci support.

Thanks, will try out and report back!
On 18.06 I get this towards the end. (i edited out all the absolute paths)

It works! I had a problem with the LEDS not working.But I flashed a new version with kmod-leds-gpio, and then it all worked. I was gonna flash the old version without kmod-leds-gpio just to make sure that that was the culprit, but then I bricked it. Oh well.
I'll chime in after I've soldered some pins to access the serial console. (which may take some time, I don't have any laying around). I tried to debrick it all the usual ways including the sercomm utility, so I guess the serial console is the only remaining option.-
did u try with the nmrpflash to debrick it ? netgear routers r literally unbrickable if the model has sercomm bootloader (custom uboot) and jwnr2010v5 has it...no matter what image u push to the router by nmrpflash or tftp, u can't damage the bootloader and as long as the bootloader is fine the router can be recoverable
I did.
Windows will say the cable disconnected, even though I set static IP. If I hold down the reset button before I plug in power and hold it a few seconds, the power and wlan leds will blink alternatively. I am then able to "not get" cable disconnected when using Lan 3 after a few seconds (but Windows shows line speed as 10mbit, not 100). I am then able to fire off nmrpflash, but nothing will happen when I plug off/on the power plug. Also no ping whatsoever, tried the sercomm tool that only works in XP (which I sucsessfully revived WNDR3700v5 with once). Tried TFTP ..I tried it all 
I just remembered I have som shady routers..
Also the reason why it bricked was that it goes to 100% cpu usage pretty fast after rebooting, the first time I managed to flash (manaully in console with mtd, but the second time everything just froze before it had completed). I was gonna try to figure out why the cpu usage went up to 100% next. (I used the same config for a MR3020 that works fine)
Ok, I'm back up. I managed to use the nmrpflash tool to revive it.
(Had to reboot and then connect/disconnect to another router, or something.. I don't really know to be honest, Windows network is like that sometimes. But now the tool works everytime so I'm just glad I didn't had to whip out the soldering iron.)
Anyways 18.06 is pretty great on this thing. Thanks! Only thing is that Luci can be very sluggish, espescially initially. Maybe writes to the flash is very slow?
This is what I managed to fit, with space to spare, using 18.06-snapshot.

Ya, I kinda nerf the spi flash read speed at first for testing..u can bump it up to 30000000 (30MHz) in here, in master it's 30MHz. See if this improve the luci experience.
I tried to up the frequency and it certainly didn't hurt. But it still is sluggish to the point of Luci timing out.
It seems to do this whenever I first connect to an AP. (Haven't tried the wan port, just wlan cLient). It seems all the backgrounds processes start "doing sh**" whenever there is an internet connection. (even if though they mostly are disabled by default, they seem to do something)
I did compare it to an old MR3020 router and this too is a little sluggish, when an internet connection is discovered, but Luci stays relatively responsive. (it is the same configuration except the ar71xx vs MT7620+zram). Anyways it's just a minor inconvenience and probably won't happen on a standard configuration. After a minute it's mostly back to normal.
