HI,

I want to know how each devices is getting powered on in sitara board.
E.g LCD is getting powered on at boot time.
So my question is which part of software code is doing this job.

Thanks and Regards,

Hi Vishnu,

The U-Boot initialization is generally happening inside board.c and mux.c which are located in <u-boot_folder>/board/ti/am335x/.

The Linux initialization is happening in <linux_folder>/arch/arm/mach-omap2/board-am335xevm.c file.

Best regards,
Miroslav
