Thanks for ur response Barun
I want to port android gingerbread source to Beagle Board XM Rev C...
Usb ports are not enabled by default as I mentioned before..

I've my own MLO and uboot.bin (which I customized it for my own splash image).
Since I couldn't use mouse or keyboard , I downloaded the prebuilt uImage from
link

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/TI_Andro
id_GingerBread_2_3_4_DevKit_2_1/exports/beagleboard-xm.tar.gz

and flashed sdcard with this uImage and my own MLO, uboot.bin and rootfs and
tried booting in Beagle Board XM Rev C.. The numlock and capslock leds are
glowing when I press keys in keyboard. But its not booting .. Here is the log,

Hi Sindhuja,
Sorry for my late response.
Can you test this and let me know.

Please comment out below code segment from arch/arm/mach-omap2/board-omap3beagle.c, you just need to use the else part and build your kernel.

if (cpu_is_omap3630()) {
/* Power on DVI, Serial and PWR led */
gpio_request(gpio + 1, “nDVI_PWR_EN”);
gpio_direction_output(gpio + 1, 0);

/* Power on camera interface */
gpio_request(gpio + 2, “CAM_EN”);
gpio_direction_output(gpio + 2, 1);

/*

  • TWL4030_GPIO_MAX + 0 == ledA, EHCI nEN_USB_PWR
  • (out, active low)
    */
    gpio_request(gpio + TWL4030_GPIO_MAX, “nEN_USB_PWR”);
    gpio_direction_output(gpio + TWL4030_GPIO_MAX, 1);
    } else {

Hi,

I have the same issue. However, I am very new to the rebuilding of
kernel. Is there any guide that I can follow and build the kernel?
Hope to hear from you soon as I am really rushing for my final year
project dateline.. Thanks!
