Can I use ISD51 in the target system of at89c51? I tried it. But if I use the ISD51 debugger and select the debugger option"verify if the application in ROM is identical to current project", the connetion error will happen. otherwise,the debugger can connect to the target correctly. Any solutions or suggestions? Best regards Lakeshu Hu
Which communication error?
the ISD51 Monitor Error is below: There was no reply from the target system! Please check the following items: -make sure the target system is connected to the selected com port -make sure the ISD51 is linked to your application -make sure the loaded application matches the ROM content -review the initialization of the serial interface(baudrate) -the application must not disable the serial interrupt for more than 5 seconds My other problems:1.If I don't select the option "Verify if Application in ROM is identical to current project",the ISD51 debugger can connect to my target system(AT89c51).what's the problem? 2.If the ISD51 debugger connects to my target system(AT89c51),I can only run my application program using step-into.If I use the step-over,the ISD51 debugger will freeze(out of order).
Thanks for your help. lakeshu hu
