My program is writed in asm with ax51 v2.74. Code size is about 83200 byte and using rom huge complier directive. All my code above 64k use ejmp ecall & eret.It work well in keil ,but when it is runing on my termial device,it fails to work.If I delete some function and reduce the code below 64kb ,it can work correctly on my termial device. I have read the apnt_160.pdf the example in keil direcotry.But I don't know what's wrong about my program.
