The embodiment of the invention discloses an information processing method, an apparatus and a device, wherein, the method comprises the following steps: obtaining a first instruction, wherein, the first instruction is used for instructing to read/write data from a memory; If there is a fault address in the address corresponding to the first instruction, determining a second starting address according to the fault address; A read/write data operation is performed based on the second start address.

Information processing method, electronic device and computer storage medium

The invention relates to a method and a system for testing embedded software. The system comprises a host computer, a controller chip and a sampling chip. The method comprises: when the host computercompiles a control program, defining data to be monitored as a global variable, and compiling and generating an output file and a corresponding. map file; then, programming the generated output file into the controller chip, after programming is completed, the controller chip running the program, driving a device to work, and collecting data information generated by work of the device; the host computer extracting the global variables and corresponding storage addresses stored in the.map file; according to the storage addresses of the global variables to be monitored, receiving corresponding data information generated by operation of the device, processing the data information, to draw an image. The method can effectively solve shortcomings of inconvenience, insecurity and the like existing in field tests of an existing embedded test technology.

Method and system for testing embedded software

The invention provides an on-board software dynamic loading method for supporting address redirection. A simple, highly-reliable and redundant on-board software address redirection loading method canbe implemented. The method includes the steps: firstly, writing an embedded software link configuration file; secondly, detecting a memory when a program is started; thirdly, on-board software globalattribute componentization: packaging all global attributes into an attribute of a component known as a program component; fourthly, program component instantiation: mapping the program component defined in the third step onto a healthy memory starting address by acquiring a starting address saved in a global register to instantiate the program component; fifthly, compiling and linking the whole program to form a programmable binary program file; sixthly, programming the binary program file onto a target device, and normally starting the target device in a power-on manner. The all global attributes can change and include attributes with initial values and without initial values.
