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.

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".

    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!” : (

    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.
