Hi All,
I'm working on android ported on a beagleboard.using the rowboat version. I was faced with some errors related to the smart reflex VDD
autocompansation and as a resolution I wanted to change the current linux kernel to the linux-omap-pm latest branches with smart reflex patches.
My question now is how can I start the android init from the linux-omap kernel?..

Any help would be appreciate
Thanks in Advance
Best Regards
Mai

Hi Mai,
You can keep android FS in ext3 partition, and invoke its init as usual via kernel arguments..

for eg, in rowboat env,
uImage -> will be the linux-omap-pm kernel image
init =/init -> in bootargs will load android init from mmc partition 2.

Beagleboard# setenv bootcmd 'mmc init; fatload mmc 0 84000000 *uImage;* bootm 84000000'
Beagleboard# setenv bootargs 'mem=128M androidboot.console=ttyS2 console=tty0 console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw *init=/**init *rootwait omapfb.video_mode=640x480MR-16@60' Beagleboard# saveenv
Beagleboard# reset
