Hi , stephanyr

I’m also trying to follow “the dsi porting guide” and actually I have same question about .
“cd $ANDROID_BUILD_TOP/kernel”

Did you “mkdir” kernel folder @\data or did you find $ANDROID_BUILD_TOP/kernel ?

And how did you do the below command.
“cd $ANDROID_BUILD_TOP/ bootable/bootloader/lk”

Thanks in advance.

ANDROID_BUILD_TOP just means the directory that contains the android source. Its the fully qualified path to a directory that looks something like: APQ8016_410C_LA.BR.1.2.4-01810-8x16.0_5.1.1_Lollipop_P2/
