[U-Boot] building and updating u-boot on redboot based board

Hello U-Boot Alias, I am a newbie in using embedded boards and have few questions please kindly help me.

1. How to know if u-boot image I have build is build correctly? 2. I have redboot on my EP9302 SOC (Cirrus logic), can I load u-boot in memory and test if it works? What will be the memory address I need to download the image? 3. How can I burn the u-boot image if I find every thing ok?

Regards, Vipul.
