Hi, how did you connect serial cable?

Bests,

Nuno

Again, if one just changes the filename from openwrt-ramips-uImage-initramfs.bin to  firmware.ram is it still necessary to access the router serial console?

It seems to me that the ethernet registration in target/linux/ramips/files/arch/mips/ralink/rt305x/mach-whr-g300n.c is never run.

The platform setup in target/linux/ramips/files/arch/mips/ralink/common/setup.c is always running the generic setup:
enum ramips_mach_type ramips_mach = RAMIPS_MACH_GENERIC;

    static int __init ramips_machine_setup(void)
    {
            mips_machine_setup(ramips_mach);
            return 0;
    }

I'm trying with hard coding the following in setup.c:
enum ramips_mach_type ramips_mach = RAMIPS_MACH_WHR_G300N;
That should make the machine specific initialization to run.

However I have yet to solder serial cable in order to see what happens.

Yes, you are right, it is not going into that routine.  I ran into this problem a couple weeks ago with a different RaLink board but it still used the RT3052 chip.   Here is a solution for testing....

In u-boot, hit option # 4

Then enter

setenv bootargs 'board=WHR-G300N'; tftpboot 0x80800000  openwrt-ramips-uImage-initramfs.bin; bootm

by the way, if you have a different board, you might want to use a different board name.  Here are a few other examples of valid boot sequences:

setenv bootargs 'board=WHR-G300N'; tftpboot 0x80800000  openwrt-ramips-uImage-initramfs.bin; bootm
setenv bootargs 'board=FONERA20N'; tftpboot 0x80800000  openwrt-ramips-uImage-initramfs.bin; bootm
setenv bootargs 'board=V22RW-2X2'; tftpboot 0x80800000  openwrt-ramips-uImage-initramfs.bin; bootm
setenv bootargs 'board=DIR-300-revB'; tftpboot 0x80800000  openwrt-ramips-uImage-initramfs.bin; bootm

If you do this, it will boot properly, and ethernet will start working using the stock OpenWrt.

Now, my big problem is that I am trying to get USB working on my RT3052 board.  There is no code currently there to support it.

The RT3052 is USB OTG compatible.   I tried compiling and installing the DWC_OTG driver for it. However, on installation, it gives a bunch of symbols not found for symbols like: "usb_create_ncd".   So apparently UsbCore is not being loaded (even tho it is checked in the kernel config).  I am not sure how to get USBCORE to load or how to fix things from this point.   I think this USB subsystem might require some modification by the OpenWrt porting experts....

That has done the trick (based on the instructions at the beginning of this thread).
I'm compiling an image with

Tried that and it didn't work.

Currently the board is being detected (during bootup) as
MIPS: machine is Generic Ralink board

If we use option 4 and pass 'board=WHR-G300N'; then the board is detected and seems to be good.
MIPS: machine is Buffalo WHR-G300N

Swapping
enum ramips_mach_type ramips_mach = RAMIPS_MACH_GENERIC;
for
enum ramips_mach_type ramips_mach = RAMIPS_MACH_WHR_G300N;
in target/linux/ramips/files/arch/mips/ralink/common/setup.c didn't help.

As I'm not fully up to speed on this, can someone tell me how the board is detected (the process and more specifically which files / functions are involved)

I see there is a mention in target/linux/ramips/files/arch/mips/include/asm/mach-ralink/machine.h
I tried swapping the order in there to have RAMIPS_MACH_WHR_G300N, at the start, but to no avail.

As a "quick hack" for those who want to see openwrt running on these (Note it may cause other kernel issues, I haven't yet looked at what other kernel customizations this does, or breaks)

make kernel_menuconfig
Kernel Hacking --->
Default kernel command string append board=WHR-G300N
The entire line would then be
"console=ttyS1,57600 rootfstype=squashfs,jffs2 board=WHR-G300N"

Note without the "

Then the normal make world

So to get something working, build as above,
Plug the WHR-G300N => switch => PC
Set the PC to use the ip address 192.168.11.2 netmask 255.255.255.0
run a tftp server on the pc
save / rename openwrt-ramips-uImage-initramfs.bin to firmware.ram and power the WHR-G300N.

Currently the image isn't written to flash when it's booted, the default is to copy time image to ram and execute.
If someone wants to look at http://www.denx.de/wiki/DULG/UBootScripts or http://www.denx.de/wiki/DULG/Manual in general about the boot time scipts. Other projects have written an image that loads the image AND writes it to memory.

We can use mtd to write the above image (copy it to /tmp on the WHR-G300N and then write it)
mtd -r write openwrt-ramips-uImage-initramfs.bin openwrt

Now the only problem is the wireless
Should be RT2860 which is in the staging drivers. I can't yet see how to select it. It seems commented out (or similar) in openwrt.
The drivers are there build_dir/linux-ramips_rt305x/linux-2.6.30.9/drivers/staging/rt2860
Normally (regular linux kernel)
Device Drivers --->
  Staging Drivers --->
    <M> Ralink 2870/3070 wireless support

Edit: There looks to be the wireless in a later version of trunk.  Lets see if that will compile a stable image.

Hi, Timothy.

buildroot -> make menuconfig -> "Kernel modules" -> "Wireless Drivers" -> "kmod-rt2800-pci............. Ralink Drivers for RT2x00 cards (RT2860 PCI)"
Is this?

bye
zukky

Yes I think that is it.
However in trunk I downloaded yesterday, Busybox has some problems, that can be worked around, but the kernel module isn't compiling.

But rt2x00lib.ko is still not being build.

I'm going to try revision 17175 as 17176 has compat-wireless 2010-01-15 which is the package that isn't compiling
Maybe compat-wireless 2010-01-13 works

Note busybox seems to have a problem with it's module tools (you need to use the simplified one rather than the defaults)

compat-wireless-2010-01-13 doesn't work either.
Raised a ticket for someone to look at it.
I'll probably look again tomorrow

With a bunch of fiddling I managed to get a compiled image, but the wifi is still an issue

I've tried compiling the other parts of the rt2x00 friver (led / firmware etc) with other unknown symbol issues

Also jffs2 and squashfs seem to have issues on boot so I'm having to do lzma compressed ramdisk.
the module utils were complaining at compile so I was using the simple one in busybox

Can you check and see what happens if you compile with usb-core. On my kernel/build I found that the new compat.ko requires usb-core in the new compat-wireless. I have no idea if that is the case for what you are doing, but in my case it resolved the problem. I also had to rename /etc/modules.d/20-usb-core to something prior to 20-mac80211.

rt2x00lib: Unknown symbol rt2x00crypto_key_to_cipher
rt2x00lib: Unknown symbol rt2x00crypto_create_tx_descriptor

I had the same output as you above, except mine said ath9k and mac80211 unknown blah blah.

I posted Ralink AP SoC SDK in another thread. I managed to compile a firmware from it and wireless works very well.

That may hit one of the other issues with the current state of this.

I can only currently build ramdisk images. If I do squashfs or jffs2 I get ALOT of jffs2 errors as it tries to boot, then it does before I can open a console.

Note I've been able to boot the ramdisk image, then write the squashfs image and I get the above message.

Do I need to reformat the flash, I thought that's what "mtd write openwrt-ramips-squashfs.img openwrt"

Sorry to intrude on this fascinating thread, but It seems that you have explored this Buffalo router extensively.

We are a group of users who have flashed DD-WRT on the Buffalo WHR-G300N.
This group is desperately trying to revert to the original Buffalo firmware for a variety of reasons.

We have tried:

1)GUI flashing. Does not work.
2)TFTP. Transfer occurs, but the firmware does not flash or install.
3)Telnet commands:

cd /tmp
wget ftp://xxx/firmwarexxx

then

write firmwarexxx linux

or

wget -O /var/firmware ftp://xxx/firmwarexxx

then

mtd write /var/firmware linux

Are also unsuccessful.

Is there any advice you can give to successfully revert to Buffalo firmware?
TFTP technique, specific Telnet commands or serial cable?

Many thanks.
