This may be a trivial question, but I hope that someone can answer me. I am bring up u-boot on 8xx.

While doing source level debugging under ddd, whenever I do step, stepi, next or nexti I see green instruction pointer jump all over the code. e.g. it would go to first line, than third line, than 7 line. If I look at machine code window, it is running in normal predictable way.

That is typically because the compiler optimizer has re-ordered your program. ddd is showing you which line is being executed and the machine code window shows sequential instructions, but those instructions are _not_ for sequential source lines.
