Compiling U-Boot for i.MX27ADS

[#1]

These instructions used ltib-imx27ads-20071219.

First, get u-boot v2.0:

git clone http://git.denx.de/u-boot-v2.git u-boot-v2 

Enter the U-Boot directory:

cd u-boot-v2 

Export the proper compilation paths and environment variables:

export ARCH=arm

export PATH="$PATH:/opt/freescale/usr/local/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/"

export CROSS_COMPILE=arm-none-linux-gnueabi-

Configure it for the i.MX27ADS board:

make mx27ads_defconfig 

You may want to enable the FEC driver:

make menuconfig 

And go to Drivers -> Network drivers and select Yes on i.MX FEC Ethernet driver

Exit the config menu (don't forget to save the configuration) and just make it:

make 

Or if you prefer the verbose mode

make V=1 

After a quick build, you should get a uboot.bin on your current directory. I used the ADS Toolkit to program the NOR flash.
