Hi everyone,
the subject basically tells it all: I have a dirt-cheap BR6104K around and would like to run OpenWRT on it.
It's based on the ADM5120. However, when compiling kamikaze, I have the choice between little and big
endian, and I haven't been able to figure out which one I need. 
Please give me a hint..
Florian
BR-6104KP is little-endian.
Thanks a lot. I'll give it a try right now.. stay tuned 
All right, here we go: I had to make some minor changes to the kernel to make it compile, but it flashed and booted all right, up to the flash initialization:

Kernel panic - not syncing: Attempted to kill init!I have to admit I'm too tired to follow this through now, so I'll post it here for reference and go to bed for the moment
Good night,
Florian
After a bit of debugging, I've traced the problem to the following code in drivers/mtd/chips/gen_probe.c, line 130:
for (i = 1; i < max_chips; i++) {
cp->probe_chip(map, i << cfi.chipshift, chip_map, &cfi);
}The actual bus error happens a bit farther down the call stack, in drivers/mtd/chips/cfi_probe.c, line 85:
val[0] = map_read(map, base + osf*0x10);At this point, base = 0x00200000 and ofs = 2.
When I remove the loop in drivers/mtd/chips/gen_probe.c, the kernel oops doesn't happen anymore, but the root fs can't be found:

VFS: Cannot open root device "<NULL>" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)Obviously, the code in gen_probe.c is needed to actually make the MTD device work, but I'm not completely sure what it does.
Can somebody help me with some hints?
Thanks, Florian
The most recent kernel I have working with this board is this one:
http://nano.gmxhome.de/linux-2.6.17.11- … ch.diff.gz
With these instructions (more or less):
http://www.student.tue.nl/Q/t.f.a.wilms/adm5120/
Maybe something in the mtd driver has changed between 2.6.17.11 and
2.6.21.1?
By the way - I have now caught up with you - I did the same thing and
got the same kernel panic as you. I'm also very interested in fixing this.
Have you already tried this patch?
https://dev.openwrt.org/ticket/1768
I haven't yet had time to try it out, but maybe it's just what we need.
Flo
Update: this patch has already been merged into SVN. I've been trying to build a new image for the EASY5120 profile, however, this has failed so far.
First, the patch target//linux/adm5120-2.6/patches/140_cmdline-hack.patch is broken,
but this was easy to fix.
Problem two:

Here's what happens if you
a) take the newest svn source
b) remove the block at line 131 of build_mipsel/linux/drivers/mtd/chips/gen_probe.c
c) use make kernel_menuconfig to set MTD_DEBUG to 2
d) flash the resulting openwrt-adm5120-2.6-squashfs-br-6104k.bin

Kernel panic - not syncing: Attempted to kill init!I think we're almost there, it says VFS: Mounted root (squashfs filesystem) readonly.
So now the question is why init crashes..
Florian
Basically, we have two different bugs here, one in the build system and one in the kernel.
Therefore, I have opened two tickets:
https://dev.openwrt.org/ticket/1855 for the kernel panic
https://dev.openwrt.org/ticket/1852 for the build failure
Florian
Have you already tried this patch?
https://dev.openwrt.org/ticket/1768
I haven't yet had time to try it out, but maybe it's just what we need.Flo

I'm keen on this Edimax box since this article in c't. I could follow your instructions until the kernel panic. Many thanks for your posts, I would have given up without your hints! But now let's help you. The last steps have been:
- enable in the kernel the "mini fanout overlay system" in filesystems (mini_fo)
- add libgcc (openwrt configuration: Base system)
- add udevtrigger (openwrt configuration: Utilities)
I've temporarily added the devices from http://forum.openwrt.org/viewtopic.php?id=11021 and got some helpfull output from the preinit script. But finally they're not required to boot OpenWrt.
HTH! I happily answer all your questions!
Bernhard
This is totally awesome work! At revision 7576 everything is looking very good, however the USB host controller does not seem to do anything when a device is plugged in.
I think this is because there is no option to chose adm5120 HCD from the top-level "make menuconfig". It would be nice to enable this so we can experiment with different devices, even if there are many bugs!
Many thanks...
Alright.. It took me a while to get it up and running, but now I have step-by-step instructions for the Edimax devices:
1. Get a fresh checkout of kamikaze (rev. 7671 works).
2. Downgrade memory.c: svn up -r 7630 target/linux/adm5120-2.6/files/arch/mips/adm5120/memory.c
3. Apply the following patch using patch -p0:

7. Profit!
Unfortunately, I'm quite sure that these patches are probably going to cause a lot of breakage with other devices, so I'd need some help from the true kernel hackers to really integrate this into the main OpenWRT tree.
Florian
P.S. If you have a bit of time, please try this, so I'm sure I didn't forget anything..
Oh, thanks, I'm already running the latest revision on the BR-6104K. There have been no more replies to this thread, therefore I wrongly assumed that there's not much interest in patches. I'm quite new to openwrt and still watching the development process.
DRAM-detection doesn't work any more, and my Macronix chip MX29LV160CB needs another ID:

Of course I unterstand that work is in progress and nothing is finished yet. At the moment I can't cleanly enable tweaks for the BR-6104K, because the code doesn't know that it's running on a BR-6104K. There's neither a compile-time configuration nor a runtime detection for this router. I've no idea how to distinguish between a BR-6104K and any other adm5120 board at runtime.
I don't know which way to go, therefore I'm still watching your commits!
Should I publish all my quick&dirty patches & configs required to run openwrt on BR-6104K? Somewhere on openwrt.org or on my webspace?
Why don't you just post your patches here? I would like to look them through in order to see what you have changed. For example, what does the patch in your last post do? Does it probably make my second patch unnecessary?
I noticed that I forgot myself to mention what my patches do:
- downgrading memory.c avoids the system to wrongly detect double memsize (but you could probably also just add "mem=16M" on the kernel command line)
- the first patch enables the four flash partitions to be found, the edimax loader seems to use the same flash layout as CFE
- the second patch avoids a kernel panic when probing for additional flash chips - perhaps your patch also does this.
In general, I'd suggest that we should discuss our patches here and, when we have decided on a complete set, should open a ticket with the merged patches. As for the topic of runtime detection: there is already a patch which I mentioned above for the easy5120 boards, which just adds another profile. I'd say that this is the easiest way. Otherwise, we might try to find the signature of the edimax bootloader at the begin of the flash..

Ok, please give me 1 or 2 days ...
For example, what does the patch in your last post do?
There's a new fixup for the location of the bootblock in Macronix flash chips:
https://dev.openwrt.org/browser/trunk/t … h?rev=7618
The fixup didn't trigger on my MX29LV160CB. I've added the CFI-version of this chip.

Ah, thanks for the hint.
- the second patch avoids a kernel panic when probing for additional flash chips - perhaps your patch also does this.
I'm not quite sure, if your patch is still in my source. I've to check this later.

Ok, I'll post my patches here. A profile just adds some packages. I don't know how to enable tweaks for the edimax in the source. I'd like to add the BR-6104K to the list of boards in adm5120_info.c!
Otherwise, we might try to find the signature of the edimax bootloader at the begin of the flash.
No more xmodem :-{] I'm using the tftp-bootloader from midge: http://midge.vlad.org.ua/wiki/bootloader-with-tftp. I'll see if I find some usefull in the boot block.
All adm5120 files for Kamikaze 7.06 are still in development. I know developers to rewrite a big part of code, so we have to wait to have total support for all the devices
I'm somewhat unhappy about the move from compile-time configuration to runtime detection because of two reasons: it breaks things on edimax and it consumes space on the very tight 2 MB flash. Of course I unterstand that work is in progress and nothing is finished yet.
I raised a ticket concerning non-working USB on the adm5120, and it was rejected. The interesting thing was that the developer said the USB host controller would be auto-detected, resulting in compiled-in host controller. Some of these devices don't use the onboard controller (I have a adm5120 device in front of me now with 4 USB ports on a PCI VIA chip), so why bloat the kernel with this?
With the greatest respect to the openwrt developers (particularly since I've not submitted any code!), auto-detection is nice from a usability point of view, but Openwrt requires quite a high level of knowledge to use in the first place, so I doubt there is anyone who can't read their board model and find out what hardware it has.
I have written a patch which allows the adm5120-hcd driver to compile as a module and load up to the root hub initialization.
Unfortunately, at least on my hardware, the interrupt code still seems to be buggy, as plugging a new device doesn't trigger an interrupt most of the time.
Here's the patch: https://dev.openwrt.org/ticket/1972
I'd be glad if somebody else can give this a try and see what happens on other hardware.
Thanks, Florian
Hello guys. Thank you all for your work. I will handle separately the HCD problem and the 2MB/Flash problem. Could you please post your patches on the trac with the relevant parts you needed to change so that we can plan on merging them to SVN ?
I've put my flash-related patches in this ticket: https://dev.openwrt.org/ticket/2012
The second one is still a rather crude hack. If anybody has a better idea, go ahead..
Florian

VFS: Mounted root (squashfs filesystem) readonly.
Freeing unused kernel memory: 132k freed
Warning: unable to open an initial console.
Kernel panic - not syncing: Attempted to kill init!What it is necessary to open an initial console? Any help is much appreciated.
Hm.. I'm not quite sure about this bug, but I suspect it's not the console, but the root fs instead - the message "VFS: Mounted root (squashfs filesystem) readonly." is probably misleading. I have noticed that your kernel command line doesn't contain the following: "rootfs=jffs2,squashfs,yaffs2" - perhaps you can give that a try and add yaffs2.
Florian
Volker, your kernel looks good and you're very close. The kernel panic just tells you that init (in our case: preinit) exited, which must not happen.
yaffs2 is not necessary in the command line, the root file system is squashfs, so "rootfs=squashfs" would be sufficient.
The message "Warning: unable to open an initial console." is normal. When init (= busybox) starts there's not a single device in /dev. I was stuck at the same point and added some devices to the image (see my posting above). This way I caught some valuable error messages (missing libraries). I don't know exactly, which device(s) are important, just try with console, tty0, ttyS0, stdin, stdout, null, zero, ...
Make sure that all tools used in the scripts "preinit" and "init" are in the image, including the libraries! If preinit makes it's way down to the start of "udevtrigger" then you'll see the "- preinit -" message.
I also played too much with the configuration, here is what I missed:
- libgcc (openwrt configuration: Base system)
- udevtrigger (openwrt configuration: Utilities)
- special mount-utilities
Good luck,
Bernhard
