Hello ,
I invoked the Linux kernel on ALCHEMY DBAU1100 by U-BOOT.
The processing which resets USB-OHCI of the head of a kernel is not
completed. (refer to *)
Au1100 does not indicate "reset is completed."
Is this phenomenon experienced?
In addition,
this phenomenon is not encountered when starting a kernel by YAMON.
*:
arch/mips/au1000/common/setup.c
#ifdef CONFIG_USB_OHCI
// enable host controller and wait for reset done
au_writel(0x08, USB_HOST_CONFIG);
udelay(1000);
au_writel(0x0E, USB_HOST_CONFIG);
udelay(1000);
au_readl(USB_HOST_CONFIG); // throw away first read
while (!(au_readl(USB_HOST_CONFIG) & 0x10))
au_readl(USB_HOST_CONFIG);
#endif
Best regards,
Nyauyama

Yamon initializes the CPU and then Linux doesn't have to touch too many
registers. I'm guessing u-boot doesn't setup the clocking correctly, or
at all, and that might be your problem. The Yamon code for these boards
is available and it's easy to read the initialization code. Take a look
at it and that should solve your problem.

Thank you for advice.
I solved by setting up Frequency Control 0 register (FE2, FS2)
and setting 100 to a Clock Source Control register (MIR).
However, in U-BOOT and YAMON,
behavior of a kernel differs about USB-KEYBOARD.
A kernel is started using U-BOOT:
USB-KEYBOARD is not recognized.
A kernel is started using YAMON:
USB-KEYBOARD is recognized.
I am investigating this phenomenon now.

I can't tell without the manual in front of me what it means to write
100 to the clock source control reg, so I can't tell if you're setting
the right frequency. If I remember correctly, you need the clock to be
48MHz. Use the values that yamon is using that should do it. Also, there
are multi-use pins that need to be set appropriately. I don't remember
if everything was set in Linux or if we allowed yamon to do it. Finally,
if you get all the software right and it's still not working, check the
hardware design as well :)

The problem which I was investigating was solved.
USB of Au1100 uses AUX_PLL as a clock source.
The setting value of AUX PLL Control Register was mistaken.
When I corrected it, USB-KEYBOARD worked.
Eric, Pete,
I appreciate to you.
