how to screen the usb detect function in uboot

winds2001

my uboot is uboot2013.01.01-psp06.00.00.00(SDK6.0), when i power up my board ,the uboot will detect the usb,and the debut terminal shows:

U-Boot SPL 2013.01.01 (Sep 29 2014 - 10:41:06)

Could not probe the EEPROM; something fundamentally wrong on the I2C bus.

Could not get board ID.

musb-hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, bulk combine, bulk split, HB-ISO Rx, HB-ISO Tx, SoftConn)

musb-hdrc: MHDRC RTL version 2.0

musb-hdrc: setup fifo_mode 4

musb-hdrc: 28/31 max ep, 16384/16384 memory

USB Peripheral mode controller at 47401000 using PIO, IRQ 0

musb-hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, bulk combine, bulk split, HB-ISO Rx, HB-ISO Tx, SoftConn)

musb-hdrc: MHDRC RTL version 2.0

musb-hdrc: setup fifo_mode 4

musb-hdrc: 28/31 max ep, 16384/16384 memory

USB Host mode controller at 47401800 using PIO, IRQ 0

Hi,

From your log I saw that you use a custom board and the first and second wrong messages are for reading from eeprom. This messages you can remove if you commented in s_init() read_eeprom() and i2c_probe() procedure. If you want to not using a usb in a u-boot you cannot execute arch_misc_init(void), see it:

int arch_misc_init(void)
{
#ifdef CONFIG_AM335X_USB0
   musb_register(&otg0_plat, &otg0_board_data,
       (void *)AM335X_USB0_OTG_BASE);
#endif
#ifdef CONFIG_AM335X_USB1
   musb_register(&otg1_plat, &otg1_board_data,
       (void *)AM335X_USB1_OTG_BASE);
#endif
   return 0;
}
