| Abstract: | The main function of aeronautic computer is communication information process.The communication initialization files and record data files store in flash disk.The files download from and upload to target system through high-speed serial port.When upload communication initialization files to target,it may reboot.For fault analysis and recurrence,Setup simulation environment.Through analyzing driver code,we catch the fault and give some ways to solve it.These ways are testified feasible under simulation envir... |
