my AGDI dll met problem in bankswitch. I use C:\Keil\C51\EXAMPLES\Bank_EX1 project to debug the bankswitch function.for example,when code jumps from common area to B01:0x8000,the keil disasssembly window show c:0x8000 and keil debugger get instruction from c:0x8000.In memory window,I found the B01:0x8000 has the right code which I had download into flash.the project can work well with keil simulator. why they are not identical? why it will jump to c:0x8000 with DLL? In the apnt_145 ,it mentions "the amBank0, amBank31" etc.How to use them? thank you!!
