I'm very glade to have a changce to make a communication with everyone here,although my English is very very poor! As a beginner,I'm afraid that I can't get well with keil software! What i used is keil c166 software,but i can't locat the section on a fixed memory position,for example, section1( which I had defined it in the program ) and I want to locate it on the segment(80000h - 8ffffh),what should i do? If it is possible that you can give me an example,i will thank godness,and thank you!
