Error while rebuilding the kernel

[milkyway]

Hi

I am using BeagleBoard Rev C3 runnign Ubuntu. I need to rebuild the kernel in order to enable the i2c-2 channel. So I did the following changes to 'arch/arm/mach-omap2/board-omap3beagle.c' file.

a) in omap3_beagle_i2c_init(), added:

omap_register_i2c_bus(2, 400, NULL, 0);

b) in board_mux[], added:

static struct omap_board_mux board_mux[] __initdata = {
 OMAP3_MUX(I2C2_SCL, OMAP_MUX_MODE0),
 OMAP3_MUX(I2C2_SDA, OMAP_MUX_MODE0),
 { .reg_offset = OMAP_MUX_TERMINATOR },
};

But while building the kernel by using build_kernel.sh form

https://github.com/RobertCNelson/stable-kernel

I am getting the following error.

error: Error building trees

How would I solve it? Please help me

Ah.. so it's been awhile (more then a year) since i've personally
booted any of those kernels... But you shouldn't have to patch that
file, i usually enabled that i2c port by default.. Note this is only
in reference to v3.7.x branches, as everything else is foggy and too
"old" for me..

Looks like you corrupted the ./KERNEL directory or the orignal git
clone.. First try deleting the ./KERNEL directory, if that doesn't fix
it you may have disconnected the git objects..
