Subject: [U-Boot] USB host on the AT91sam9g45
Date: Thu, 30 Sep 2010 23:43:08 +0200 [thread overview]
Message-ID: <201009302343.08924.korgull@home.nl> (raw)
Hi,
I wonder if anyone has used USB host on the AT91sam9g45.
In current u-boot-usb, USB host can be configured, but I can't make it work. I
used the configuration from the AT91sam9m10g45 regarding the USB host part.
It does the following (usb storage device is attached)
Sam9> usb start
(Re)start USB...
USB: scanning bus for devices... 1 USB Device(s) found
scanning bus for storage devices... 0 Storage Device(s) found
Sam9> usb info
1: Hub, USB Revision 1.10
- OHCI Root Hub
- Class: Hub
- PacketSize: 8 Configurations: 1
- Vendor: 0x0000 Product 0x0000 Version 0.0
Configuration: 1
- Interfaces: 1 Self Powered 0mA
Interface: 0
- Alternate Setting 0, Endpoints: 1
- Class Hub
- Endpoint 1 In Interrupt MaxPacket 2 Interval 255ms
Below are the related config items :
#define CONFIG_ARM926EJS 1 /* This is an ARM926EJS Core */
#define CONFIG_ICNOVA_ARM9 1 /* It's an ICnova SAM9G45 OEM boardR */
#define CONFIG_AT91SAM9G45 1 /* It's an Atmel AT91SAM9G45 SoC */
#define CONFIG_AT91_LEGACY 1 /* needed for some defines */
#define CONFIG_ARCH_CPU_INIT
#undef CONFIG_USE_IRQ /* we don't need IRQ/FIQ stuff */
/* USB */
#define CONFIG_USB_ATMEL 1
#define CONFIG_USB_OHCI_NEW 1
#define CONFIG_SYS_USB_OHCI_CPU_INIT 1
#define CONFIG_SYS_USB_OHCI_REGS_BASE 0x00700000
#define CONFIG_SYS_USB_OHCI_SLOT_NAME "at91sam9g45"
#define CONFIG_SYS_USB_OHCI_MAX_ROOT_PORTS 2
#define CONFIG_DOS_PARTITION 1
#define CONFIG_USB_STORAGE 1
Any ideas what I can check ?
Best regards,
Marcel
