That's tragic. I just picked up a Netgear WNDR4300 (openbox on sale at the

be mostly the same hardware as the WNDR3700v4 and the TP-Link WDR43[01]0,
with things just wired up slightly differently.

As I understnad it, the difference between the WNDR3700v4 and WNDR4300 is that the 4300 has a slightly better wireless chip.

Unfortunantly from what I've seen so far, they did something wierd with the storage and as a result the stock openwrt can't access it. I've seen reports of people getting it to run from an initramfs, but this means that no settings can be preserved across reboot.

If you've seen anything different, I'd be very interested to hear about it (I picked up a 3700v4 and a couple 4300's for testing)

according to a birdie, "it looks like it's an ONFI with quirks, or nobody has realised that it's ONFI at all.". Perhaps that's enough clue to get someone started? but I fear jtag debugging will be needed. Flash chips tend to have interesting race conditions....

I'd be interested in your netperf testing setup. With the AR71xx chips
going out of style, the AR934x series is probably our best bet for readily
consumer-available hardware with open-source friendly SoCs. (Maybe a Xilinx
Zynq-based router funded through Kickstarter? =)

This is all pretty new stuff, perhaps some more performance can be gleaned
by tuning the compiler optimizations (-march=74Kc?), and perhaps the
AR8327N switch chip could use someone poking about its driver (the rtl8366s
in the WNDR3800 _has_ been around a while). Although, in all honesty, the
omission of that second ethernet port could just be a coffin nail.

Helpfully, the WNDR4300 has 128MB of NAND flash, as does the WNDR3700v4. So
compiling a full CeroWRT distribution shouldn't be a problem. The fixeth
script will need to be changed, but not much else.

PS: I apologize if this post doesn't show up where it should. I joined the
list to respond to this email, as such I naturally didn't receive the
original..
