It got compiled. But the u-boot-sunxi-with-spl.bin still generate HOST
controller rather than Peripheral USB.
I can't see it in lsusb.
Here is the u-boot console:
=> usb stop
stopping USB..
=> usb tree
USB is stopped. Please issue 'usb start' first.
=> usb start
starting USB...

Thank you Maxime!
I have removed the USB_HOST configuration. Now I get:
LD u-boot
drivers/usb/host/built-in.o: In function `ehci_usb_remove':
/home/pi/otg/mikboot/u-boot/drivers/usb/host/ehci-sunxi.c:78: undefined

Enable CONFIG_USB_MUSB_GADGET instead of HOST.

Hello Maxime!
Thank you for your answer.
How can I set "peripheral" mode on the USB in u-boot?
Thank you,
Michael

Hello Kever Yang,
Thank you for your prompt response.
This is an important feature, as 'otg' mode allow the board to stay responsive
to the computer driving it. Especially sunxi-fel and ttyusb.
I might be interested in implementing it in u-boot.
How can I do that? What is the code size
Hi Michael,
There is no 'otg_mode' in U-Boot, the driver framework is different
with kernel.
If you want to use usb device, you can use cmd like this:
ums 0 mmc 0
If you want to use usb host, you can use:
usb start
this command will enumerate all the device connect to the host port.
Hello u-booters!
I want to load u-boot-sunxi-with-spl.bin and make it operate the USB in otg
mode.
(Where the host can still be connected to the board).
How can I achieve this?
(I have attempted to use: "usb0:dr_mode=otg,phy_type=utmi\0" without success).
Thank you,
Michael
