How can I tell u-boot to boot with the ramboot= definition instead of mmcboot= ?

You need to change environmental variable bootcmd
setenv bootcmd ramboot saveenv run bootcmd
or simpler:
Stop u-boot -> and access prompt
then,
run ramboot
Hi Lucasz, that didn't work for me and I think it's because of the variables set by 'make am335x_evm_defconfig'. It seems like there are a set of standard u-boot commands and a higher level of variables set by 'make am335x_evm_defconfig' which appear in include/configs/am335x_evm.h and prevent you from using the standard u-boot commands in uEnv.txt.
For example, even after adding the following to the top of my uEnv.txt:
setenv bootcmd ramboot saveenv
I still get:
"Booting from mmc ..."
I'm struggling to figure out how to use the framework provided by 'make am335x_evm_defconfig' in uEnv.txt. Can you point me to info on how to do that?
