Linksys E2500 v2 - Unable to get OpenWrt to work

prst · March 29, 2020, 5:28pm

Hello,

I have tried to flash OpenWrt on a Linksys E2500 v2 using the stock firmware web interface but it results in a brick. I have no connectivity, i.e. http, ssh and ping not working.

File used: openwrt-19.07.2-brcm47xx-mips74k-linksys-e2500-v2-squashfs.bin

I have tried with TFTP, which seems to flash successfully but gives no result.
I have tried with a serial console + TFTP to flash, but again no result.
I am able to access the OpenWrt console using the serial connection, but I don't know how I would debug my problem from there.
I am able to flash dd-wrt or the stock firmware successfully and have web access.

I don't know how to proceed from here. I have read to my best the wiki/forums here and over at dd-wrt but don't know where to look now.

Be advised that due to lack of free drivers from Broadcom, your device will have poor wifi performance. So keep it in mind if you really want to continue with the flashing.
When you are in the console what is the output of:
ip addr; ip ro; ip neigh show; netstat -lnp
Have you tried to flash OpenWrt over DD-WRT?

I had tried flashing OpenWrt from the web interface of DD-WRT but with no success.

Posting this if it can be of any use in helping find the problem.

Very weird, there is discrepancy between the dmesg, where the interfaces are discovered and are configured and ip utility showing that there is no vlan subinterface with the IPs.
But the servers are running normally on the configured IPs.
Can you also check the swconfig dev switch0 show ?

Here is the output of swconfig dev switch0 show:

There doesn't seem to be any VLAN2 for the WAN port, but LAN ports should be working fine.
Can you also check what ifconfig -a says?

prst · March 29, 2020, 11:04pm

I ran ifconfig and got this:

But then since I have been trying with my laptop connected to LAN port 1 of the router, I decided to try with an other port (port 2, without rebooting the router) and got more output (but still can't access 192.168.1.1):

This looks much better. However judging by the RX and TX bytes shown in ifconfig, it seems to me that there is no proper communication from the physical port to the eth0.1 interface. If you run tcpdump or wireshark on the laptop are you able to capture anything from the Linksys?

prst · March 30, 2020, 1:05pm

I can see IPv6, mDNS and BOOTP related traffic coming from the MAC address of the router.

Here is a sample:

Does brctl show show that eth0.1 is in br-lan?

It appears your laptop 192.168.1.72 is expecting the router at 192.168.1.1 but it is not answering.

prst · March 30, 2020, 1:51pm

It seems so:

root@OpenWrt:/# brctl show
bridge name     bridge id               STP enabled     interfaces
br-lan          7fff.48f8b3447a98       no              eth0.1

I was wondering if the problem could be with my setup, but I guess not since DD-WRT works.

Another unusual behavior of the router is that the power LED blinks twice on power on and stays OFF afterwards. LAN LED is on and blinks when sending packets.

prst · March 30, 2020, 2:02pm

Just wanted to mention, there is an older post where people had the same problem but for the E2500 v3 and no solution for making OpenWrt work.

trendy · March 30, 2020, 2:09pm

@jow @tmomas has anyone ever managed to make this device work or should we inform the device page accordingly?

tmomas · March 30, 2020, 3:49pm

I couldn't find any reports of successfull flashing of OpenWrt on this device.

@prst Does the same happen with a snapshot image instead of 19.07.2?

prst · March 30, 2020, 4:12pm

@tmomas I just tried with the latest snapshot Sun Mar 29 22:15:39 2020 and I get the same result.

Here is my flashing procedure in case there is something I'm doing wrong.

On the router via serial:

CFE> nvram erase
*** command status = 0
CFE> flash -ctheader : flash1.trx
Reading :: CODE Pattern is CORRECT!
upgrade_ver[v2.0.0] upgrade_ver[20000] 4712_ver[0]

CODE Pattern is correct! (E25X)
Programming...done. 4263936 bytes written
*** command status = 0
CFE> nvram erase
*** command status = 0
CFE> reboot

On my laptop:

 atftp --trace --option "timeout 1" --option "mode octet" --put --local-file ./openwrt-bcm47xx-mips74k-linksys-e2500-v2-squashfs.bin 192.168.1.1

hax · October 26, 2020, 8:01pm

how did you get CFE console ? CTRL+C didn't work nor Escape

prst · October 26, 2020, 9:47pm

If I remember correctly it was Ctrl+C... Make sure your serial console is working and try hitting the keys at different times during the boot maybe.
