To: u-boot at lists.denx.de
Hi,
I am using OMAPL137EVM, using DaVinci-PSP-SDK-03.20.00.14 package and trying
to boot from USB on u-boot.
While configuring u-boot for USB support we have enabled macro's
CONFIG_USB_DA8XX and CONFIG_USB_STORAGE
in include/configs/da8xx_evm.h following below link :
http://processors.wiki.ti.com/index.php/Configuring/Building_U-Boot_for_OMAP-L137
I am using following environment variables
bootcmd=usb start; fatload usb 0:1 0xC0700000 uImage; bootm 0xc0700000
bootargs=console=ttyS2,115200n8 noinitrd rw ip=off root=/dev/sda2
rootfstype=ext2 mem=32M
I am facing following issues at U-BOOT prompt
U-Boot > usb start
(Re)start USB...
USB: scanning bus for devices... No USB Device found
scanning bus for storage devices... 0 Storage Device(s) found
Please can anyone suggest for solving issue
Thanks
