I tried to boot the latest snapshot of kamikaze on the WHR-HP-AG108

The kernel and rootfs were taken from http://downloads.openwrt.org/snapshots/atheros-2.6/. It will boot the kernel but then it won't recognize the redboot partitions on the flash.
Redboot is the original version that came with the AG108.

Here's the flash layout:

RedBoot> fis list
Name              FLASH addr  Mem addr    Length      Entry point
RedBoot           0xBE000000  0xBE000000  0x00050000  0x00000000
RedBoot config    0xBE3DF000  0xBE3DF000  0x00001000  0x00000000
FIS directory     0xBE3D0000  0xBE3D0000  0x0000F000  0x00000000
vmlinux.bin.gz    0xBE050000  0x80041000  0x000F0000  0x80041000
rootfs            0xBE140000  0x80000400  0x00290000  0x80000400

And here's the "physmap" that does not find the redboot partitions:

physmap platform flash device: 00400000 at 1e000000
physmap-flash physmap-flash.0: map_probe failed

I would attach a full log for reference but it seems I can't do it (if needed I'll post it).

Do I need special redboot partition/loader?
How do I debug this issue? I have a fully functional buildroot-ng and I can build images/use the serial console...

Mesher

PS: I tried a daily build from <another distro> and sure enough it finds the redboot partition. I'm including the log in case it's usefull

Should be fixed in r6727. Please run svn update; make target/linux-clean world.

Nbd... you're the man. It works now.

Here's the physmap now:

I'm also including a piece of serial output which you might be interested in:

Please tell me if you don't have an AG108 to work on, or if I can do anything to help out the project (I'm _not_ new to embedded programming).

In the mean time I'll give you some output: wifi0 is not present (madwifi problem?), but the modules load properly (?):

Now that the kernel works, I'll try to figure it out in madwifi 0.9.2.1 or give 0.9.3 a chance.

Thank you
Mesher.

You currently have to change the HAL that it uses. Edit package/madwifi/Makefile and replace the 'ap51' hal with 'ap43', then rebuild...

go with ap30, that's the right one

AP30 is the right one I can scan the network and I can see other AP around.

In the next days I'll be testing the AG108 to some extent. Is there anything in particular that you want me to check?

Nbd: Thanks again for fixing the redboot... It would take me ages to find it myself.

Mesher.

Hi mesher,

I have the same problem with my 2100AP

ath_hal: module license 'Proprietar
y' taints kernel.
ath_hal: 0.9.17.2 (AR5212, AR5312, RF2316, TX_DESC_SWAP)
ath_rate_sample: 1.2 (0.9.2.1)
wlan: mac acl policy registered
ath_ahb: 0.9.4.5 (0.9.2.1)
wifi%d: unable to attach hardware: 'Hardware revision not supported' (HAL status
 13)

Can you tell me how you have solved?

Thenk you

how do I rebuild the thing? I'm installing ag108 and I can't load the driver?

can you point me to some fine build?

thanks

The discussion might have continued from here.
