Hi -
Huh. I'm not sure if I've played with early printk on beagle.
If not, mind sending me the .config you're using and I'll take a look?
Oops, sorry, that second line was confusing. I was initially going to ask if you were using the android_omap3_defconfig, but clearly that's not the case as EARLY_PRINTK isn't enabled there.
So do please send your config.
You'll need it enabled in your .config as John mentioned but then on the kernel commandline the following additional magic too:
earlyprintk=1 earlycon=ttyO2,115200n81
if your kernel is older then it'll still need ttyS2 instead.
