Hi Stefano,
I am trying to add USBH2 support for MX31PDK and I am using qong code as reference.
When I add the USB related defines in mx31pdk.h (same as qong.h) :
/* USB */ #define CONFIG_CMD_USB #ifdef CONFIG_CMD_USB #define CONFIG_USB_EHCI /* Enable EHCI USB support */ #define CONFIG_USB_EHCI_MXC #define CONFIG_EHCI_HCD_INIT_AFTER_RESET #define CONFIG_MXC_USB_PORT 2 #define CONFIG_MXC_USB_PORTSC (MXC_EHCI_MODE_ULPI | MXC_EHCI_UTMI_8BIT) #define CONFIG_MXC_USB_FLAGS MXC_EHCI_POWER_PINS_ENABLED #define CONFIG_EHCI_IS_TDI #define CONFIG_USB_STORAGE #define CONFIG_DOS_PARTITION #define CONFIG_SUPPORT_VFAT #define CONFIG_CMD_EXT2 #define CONFIG_CMD_FAT #endif /* CONFIG_CMD_USB */
, the mx31pdk board no longer boots.
I also took care of the USBH2 IOMUX, but even without the IOMUX the board does not boot.
Do you see anything obvious that I am missing here? Does qong board boot fine on your top of tree git?
Thanks,
Fabio Estevam
