Topic: Linksys AC3200 EA9200 - red headed stepchild of routers?

The content of this topic has been archived on 1 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Hello, first time caller, long time listener.

I ignorantly purchased an AC3200 Linksys and then found out they haven't released a FW update on it since sometime last year and no one who does 3rd party FW seems to support it, or even the BCM chips it carries.

Is there a bounty I can pay to get that fixed, or should I ebay this assumed PoS?

I find the FW lacking somewhat from Linksys (big surprise).

Thanks,
Jeff

I don't have a serial cable here. Let me do some research and see if I can bumble through this without wasting you (or anyone else's) time further.

Thanks for your reply Zajec!

They are very cheap, you can get one for few $ with shipping and extra cables.

Long version: http://wiki.openwrt.org/doc/hardware/port.serial
Short version: look for "USB TTL" on auctions, *don't* use serial port of your PC (because of different voltage)

Gotcha. I used to have a USB to rs232 for cisco work but that was a while ago.

thanks again!

I have bootlog and nvram show for this router.
I provided them to brainslayer over at dd-wrt but have not heard back.
Would there be any interest here for them?

AFAIK a lot of work to support new devices shifted to LEDE Project. Given time (I'm guessing it's all hands on deck for upcoming 17.01 release now) people would probably respond there (forum, better yet IRC).

Thanks.

Use pastebin.com to post them and post the links. Thanks.

nitroshift

Will do. Thanks.

Uh, it's another device with two boot partitions:

Creating 6 MTD partitions on "nflash":
0x000000000000-0x000000080000 : "boot"
0x000000080000-0x000000200000 : "nvram"
0x000000200000-0x000002a00000 : "linux"
0x000000441dbc-0x000002a00000 : "rootfs"
0x000002a00000-0x000005200000 : "linux2"
0x000002c3acb0-0x000005200000 : "rootfs2"

I started working on supporting this in LEDE:
1a5cb4ac1bd0 ("kernel: add pending bcm47xxpart support for failsafe TRX partition")
7c8a36340c3a ("kernel: update bcm47xxpart failsafe partition patches")
but it's not complete yet. I need to work this out before we can support this Linksys device.

Ok. Thanks. I just posted the same info on the lede forum.

Malachi: where did you but this unit? Is it coming from US?

Yes. I bought it in the US.

Any progress?

The discussion might have continued from here.
