Hi I'm working on a Phytec Board Satrter-Kit 167 and i want to use the Serial Port for incoming Information of my mobile phone. When I write a Interrupt Srvice routine for the Recieve-Interrupt of the port, I get the Warning : *** WARNING L4: MEMORY SPACE OVERLAP FROM: 0000ACH.0 TO: 0000B0H.0 while compiling it with Keil. And when I send a character with HyperTerminal the routine doesn't execute but the S0RIR is set on 1. I think its because the monitor use this interrupt, but I switched of that the program will stop with the serial interrupt in the options for target -> Debug Information. I load the hex-file with FlashTools 16W up. Can somebody help me. How can I execute my program without the monitor for using the interrupt of the serial port? Thanks a lot
