I think you may be a bit promiscuous, this thread is not about or
base on a loongson platform.

The usb keyboard can not work. I have added the usb_keyboard.mod into

In this case I'm sure that usb_keyboard works on both yeeloong and
fuloong. I suspect the difference between David and me is that he uses
pmon and I don't and when loaded from another bootloader rather than
directly from flash GRUB skips some init routines which shouldn't be
necessary in that case, including some CS5536 init. I just have not
enough battery right now to make a test image.
I think if no ehci support, the usb device will run with full-speed or
low-speed, because of uhci/ohci support.
Keyboard is always in low-speed mode.

Hi Vladimir, I have not received you reply for some days. I think you must be very busy, so I did some works on my own way.
I tested dozens of versions between r2249 and r3229. I found that most of them can boot my machine with "--with-platform=multiboot" option rather than "--with-platform=coreboot" option. The latest one I used is r3200, I think it should
support usb device nicely. I added usb.mod uhci.mod usbms.mod usbtest.mod into the image(payload.elf), but it can not detect
my usb disk stilly. But if I plug a usb stick into my board after booting into the grub shell( grub> ), I get these message:
/*********************************************************************************/
grub> bus/usb/usbhub.c:208: total=250
bus/usb/usbtrans.c:93: control: reqtype=0x80 req=0x06 val=0x100 idx=0x00
size=8
bus/usb/usbtrans.c:120: control: transfer = 0x7fe4cec0, dev = 0x7fe36ea0
bus/usb/usbtrans.c:187: control: err=7
It looks like GRUB has seen the device but no real data was transfered.
Could you try with low-speed device? E.g. keyboard. I think you may need
ehci driver (Aleš recently coded one)
/*******************************************************************************************************/
I looked at the source code and found err7 is time out error, I don't
know how to fix it.
I need your help and anyone's advices. It is long time I have spended
on this project. So look forward to your replay.
Thank you in advance.
BRs,
Rock.
I have read the source code about the mmap of grub and of corebootV4,
I found that the size of their table header struct are not same, and
I think ,in the file "mmap.c" of grub2,on the 53rd line, the offset
of the first table item may be error.
BRs,
Rock.

I received you reply this monday, then my office PC had a
problem ,can not power on, so I write you late.
I have tried to run "dd", but got "Reading a error address".

Sorry，I am careless, my log file is not empty, please refer to the
attachment.
I would also need another memory location for full diagnostics:
sudo dd if=/dev/mem of=tables bs=1 count=65536 skip=2146422784
Looking at the code, the only way it can hang AFAICT should be fixed by
attached patch (mostly guessing)
1. I have tried the "--with-platform=multiboot" option, but when
booting it show me:
/*********************/
Welcome to GRUB!
out of memory
Aborted.
/*********************/
2. The /dev/mem you need , how can I get it? I want it should be from
the "/" , then I must enter the ubuntu.
So I use the grub1.98 as coreboot payload and boot my ubuntu11.04.
But when I copy the /dev/mem to a log file with "sudo",
I was told “You can not do it!” : (

I have found the the last version which can boot my machine, it is
the r2348. The r2349 can not boot it.
So I checked out the changelog from 2348 to 2349 :
Ironically I did it because i386-coreboot didn't work in my tests.
Could
you send me the first 128K of /dev/mem ? Meanwhile you can try
i386-multiboot port.
