Hello, I am using uV2 to develop my system. The target is an AT89C52 (ATMEL). I use CEIBO debugger in addition. When I have compiled it and ran it with the emulator, everything works... I use both xternal and internal clk, that's ok anyway... The same resulted when I emulate with the HEX output too... But the problem is, when I program to the MCU, it fails... The circuitry and firmware is proved to be correct... and I have emulated again and again with the emulator both xternal and internal clk... both KEIL code and HEX... What's wrong then? Thanks Panda CUHK EE
You gave little information about your target system design. From what you described, I am afraid that you might be on the wrong track. How about getting a scope and starting from "RESET" pin?
