OpenWrt support for AP3715i

For Developers
1

I have been trying to use the openwrt-mpc85xx-p1020-extreme-networks_ws-ap3825i-initramfs-kernel.bin guide and setup steps on this unit which results in a kernel panic on bootm go

Any advise as to what I am doing wrong?

Full set of commands to set this up is:

setenv boot_openwrt "cp.b 0xEC000000 0x2000000 0x2000000; interrupts off; bootm start 0x2000000; bootm loados; fdt resize; fdt boardsetup; fdt resize; fdt boardsetup; fdt chosen; fdt resize; fdt chosen; bootm prep; bootm go;"
setenv bootcmd "run boot_openwrt"
setenv bootargs 'board=AP3710i'
setenv ipaddr 192.168.12.251;
setenv serverip 192.168.12.171;
saveenv



tftpboot 0x2000000 openwrt-mpc85xx-p1020-enterasys_ws-ap3710i-initramfs-kernel.bin;

The Enterasys WS-AP3710i is not the same device as the Extreme Networks WS-AP3825i. Please boot from this file instead: https://downloads.openwrt.org/snapshots/targets/mpc85xx/p1020/openwrt-mpc85xx-p1020-extreme-networks_ws-ap3825i-initramfs-kernel.bin

Hello @thavincinew,

did you make it?
I also have a bag full of 3715i here and would like to donate them to a streetworker organization. Of course, this is only useful if there is a usable OS on it. That's why the first attempts didn't work for me either. Have you found a solution?

Greetings

if the 3825 image is to be used, perhaps the install instruction for the same works as well https://openwrt.org/toh/extreme_networks/ws-ap3825i

Hello @frollic

Unfortunately, it doesn't work that way. If I use the "openwrt-mpc85xx-p1010-sophos_red-15w-rev1-initramfs-kernel.bin". Then I have at least something, but an upgrade does not work. I have tried with all possible binaries which would be suitable for P1010E CPU's. When upgrading I always get the following error message:

I also have an AP3825i AP, the instructions go very well.
But not with an AP3715i.

...
If i use the AP3825i for booting ... i got a Kernel panic

Does anyone have any other ideas.
I would also give away a few of the devices,
if it is explained to me how I can image one myself.

Did you succesfull upgrade WS-AP3710i to OpenWRT ?

10

Not yet.
I will probably have to deal with the issue of cross compilation at some point.
I've never done that and I think it's very complicated for beginners.

11

I have come across some AP3715i's. Did you ever figure this out?

Unfortunately nothing useful yet.

The port is now done; see

https://downloads.openwrt.org/snapshots/targets/mpc85xx/p1010/

and here for the instructions:

@hurricos
That's great.
Thank you very much, you've just made me super happy.
Just in time, I was already thinking about throwing away the box with the APs.
Let's see if I can get them to work now.
