Question How to test embedded Linux / Startup Code


Hi,

i couldn't found any matching entries in this forum.

I've got an ARM9 Atmel SAM9G25, and it's running with an embedded Linux. Now since it's about an embedded device I want to check where i can save time and power by the startup of the device.

I know some parameters which can improve the energy savings but I only knew a few tricks to measure it. Since im not only want to test the Linux but bootstrap and u-boot in front of it too, i need a measuring method for all these 3 instances.

Can you tell which programs/algorithms can help me measure this e.g by serial port, ethernet or by creatings log files? Any links or advices?

Thanks! Greetings
