Dear All,

I am trying to compile attitude package for AP121 board but facing the problem due to my Flash I think. I have a board which is using a ar7240-nor0 flash as I know. I have compiled the code and i am able to boot but comes across this problem of Kernel panic. Below I have attached the log for console. Hope anyone can help me through this

Also Forgot to mention.....
My flash is splitted in the following way in my U-BOOT

I have 128kb of Uboot, followed by 64K uboot-env, 2.8M of rootfs, 896k kernel, 64k nvram,64k ART

Regards

If you don't change the openwrt kernel code,the openwrt kernel code will not use the u-boot passed "command line mtd info".The first 128k is u-boot,the flash last 64k is art.and also forget the nvram which only in atheros design and the history openwrt release...
You need provide more info about you project,the steps you do make the openwrt work on your ap121 board.You only want to use the openwrt kernel and reuse other design from athero SDK design?

Hello Mips,

Thanks for you reply. Actually I am using atheros u-boot and I want to port openwrt on it. Basically I have got a board from one of my friends... I am not understanding where to start. I had captured a log before which gave me the information about partitions. But when I tried to port kernel and rootfs code of openwrt, it gave me the above error. I can provide you any details you want... Let me know what you want and I can provide you the same.

Also i have to use existing u-boot as i have to return the board to my friend whenever he asks for. So how to go forward from here.

Regards
Nikhil

First you use wrong device name for your flash (should be spi0.0 I think), let me know if you need help with porting, I recently ported openWRT to AP94 (AR7161 CPU).

@Nikhil:
The default atheros SDK bootloader can't load and boot the openwrt code,you need replace it,if this step have do,the next step is more easy.
You don't need change more code to let openwrt work on Atheros AP121,because there is a AP121 target in the current code.

@mips: current code for AP121 has non matching flash layout so it's not good for nikhil this is current makefile:

ap121_mtdlayout_2M=mtdparts=spi0.0:64k(u-boot)ro,1216k(rootfs),704k(kernel),64k(art)ro,1920k@0x10000(firmware)
ap121_mtdlayout_4M=mtdparts=spi0.0:256k(u-boot)ro,64k(u-boot-env)ro,2752k(rootfs),896k(kernel),64k(nvram),64k(art)ro,3648k@0x50000(firmware)

@Nikhil:
I see more problems there, flash is not detected at all, no entry in dmesg, should probably me something like:

m25p80 spi0.0: found mx25l6405d, expected m25p80

Also as I said before, your kernelcmd is wrong, spi flash in openwrt is called spi0.0 (as per lines from openWRT makefile)

Hello Jaceq and Mips,

Actually I am stuck with this atheros u-boot and cant change it as I have to return this board after a month or so. Also as I see in the printenv of the u-boot, they have set flash to ar7240-nor. I have more console prints for you. Can anyone help me to work out with this format. Also can any one arrange a proper openwrt u-boot for this board. As i plan to remove the present u-boot code through console and tftp and when I have to return the board I can load back the u-boot. But will this work. Will the flash get detected or is it that I have to change the flash itself to workout openwrt on it..

The present log is as below

I see you already flashed kernel
From my experience it's easier to test kernels by running them from memory directly.
You used generic kernel which is wrong, I had exactly same problem with flash.
I am now looking at generic AP121 and I see that build are using initramfs...
Anyway, since you have a board, check what flash chip you have and then check if it's supported at all or not

(Last edited by jaceq on 16 Apr 2013, 19:59)

Sorry Jaceq, I myself have this particular board for a month or so and only if I am able to port openwrt in this, i will buy it.  Also Yes i had compiled for a generic flash. I think that the exact problem with the code not booting you. But how can I compile for the Flash I am using(flash used is MX25L6406EM2I. ). I can provide you the details if needed...

Thanks and Regards
Nikhil

Easiest way to go is:
Compile for AP96 target, take just kernel file, and try to run it from memory...
It will have totally wrong flash layout and will be gzipped -> meaning that it will not fit into your partition (hence run it from memory) but check if flash is supported at least with it (look for line I mentioned few posts above). If you get that to work it's a good sign but a long way to go still.

But how to run from Kernel from memory  buddy.. Can you help me with the steps..

Hey Jaceq,

I loaded a kernel file "openwrt-ar71xx-generic-ap121-4M-kernel.bin" that i directly downloaded from http://www.lispmob.org/downloads/openwrt/ar71xx  and now I am able to see my flash.. Just check the log below

Now I have to do the same.... First need to get my code to work till this part.... How to compile my code till this part jac.. Can you help me to build the same kernel as above. I think its a generic flash one. So how is this working...

Pl. help

So, flash is detect and seem to work ok (errors above are due to the fact that partition layout doesn't match).
So now what you need to do is get more into details.
Easy way from here I suppose is to:
add new partition layout that is matching your board (in target/linux/ar71xx/image/Makefile) and once you have this done, I'd say modify this line:

$(eval $(call MultiProfile,AP121,AP121_2M AP121_4M))

so it will contain your newly defined layout, for example:

$(eval $(call MultiProfile,AP121,AP121_2M AP121_4M AP121_8M))

Than recompile.
Than load freshly built kernel (you might need to flash rootfs into place for this to work).
Let us know what happens

EDIT: Now I see you downloaded image from somwhere and this particular file does not build in stock openwrt, this means they have modified makefile for image. So... it's tricker, unless they provide their source... do they?

ok jaceq..Will try and let you know... updates soon

Jaceq

I found this line bit confusing in that makefile

$(eval $(call SingleProfile,AthLzma,$(fs_64k),AP121_4M,ap121-4M,AP121,ttyATH0,115200,$$(ap121_mtdlayout_4M),917504,2818048,RKuImage))

what does different variable of this line say..Such as

,$(fs_64k) --> ?

917504,2818048,RKuImag --> ?

Can you help me with this before i make changes to the MAKEFILE

Hello Jaceq,

When I compiled my own source and loaded "openwrt-ar71xx-generic-ap121-4M-kernel.bin". I got the same output as the one above. So know I have the kernel. I have also made the changes in makefile as you said. But when I compile the same, I am not able to see any new kernel or rootfs file for 8M. Also If I need to change the partition table in the kernel where should I do it. I am not able to find it anywhere. Do you have any idea Jac

Regards
Nikhil

before you re-compile (with new settings) do:
make clean
make dirclean
and re-try

Also, post what changes did you add to your make file.

Hello Jaceq,

I added following things in the makefile

$(eval $(call MultiProfile,AP121,AP121_2M AP121_4M AP121_8M)) --> line number 919

ap121_mtdlayout_8M=mtdparts=spi0.0:128k(u-boot)ro,64k(u-boot-env)ro,2952k(rootfs),896k(kernel),64k(nvram),64k(bconfig),2952k(brootfs),896k(bkernel),64k@0x7f0000(art)ro

Added the above line since I am using 8MB flash and when i typed printenv on uboot it showed this.

Also when I make a mtdlayout for 8M flash will i get another kernel image for 8M or i should use the one for 4M only..

Regards
Nikhil

I did cleanup and then recompiled but i could not find any kernel for 8M buddy. Can you check the above and let me know. I can also send you the compilation log if you need..

Regards
Nikhil

Hi,

So you're still missing one line:

$(eval $(call SingleProfile,AthLzma,$(fs_64k),AP121_8M,ap121-8M,AP121,ttyATH0,115200,$$(ap121_mtdlayout_8M),3022848,917504,RKuImage))

I'd add it around line 830 where other AP_121 are.

Also, have a look at this: Flash layout I'd suggest to add 'firmware' partiton which covers your rootfs and kernel partitions (this is used for upgrades later etc.)

jaceq what are the values 3022848 and 917504 and RKuImage

It's size of rootfs and kernel (in bytes), I modified them for you according to your partition layout:

ap121_mtdlayout_8M=mtdparts=spi0.0:128k(u-boot)ro,64k(u-boot-env)ro,2952k(rootfs),896k(kernel),64k(nvram),64k(bconfig),2952k(brootfs),896k(bkernel),64k@0x7f0000(art)ro

OK... AS i THOUGHT... But what does $(fs_64k) and RKuImage means.
