Problems solved by technology
Once a fault occurs, it is impossible to determine whether it is due to incorrect implementation of the application program or a fault in the chip itself, or an error in the program handling process, resulting in high follow-up troubleshooting costs

Embodiment Construction
[0052] to combine figure 1 , the SoC application object code generation and loading method with self-test function, the steps are as follows:
[0053] (1) Generate the object code about the application program running in the SoC chip, and calculate the CRC check code in bytes;
[0054](2) Packing the target code and the CRC check code, that is, the calculated application program CRC check code is placed immediately after the application program target code, occupying the space of one word;
[0055] (3) Generate the target code with self-test function guide method, and put it in front of the application program target code, and form the self-test function with the self-test function together with the application program target code and the calculated CRC check code To execute object code, see figure 2 .
[0056] The boot method with the self-test function includes the following steps:
[0057] Step 3.1, initialize the SoC chip, including memory access configuration, Cache ...

The invention relates to a SoC (System on a Chip) application guidance method with a self-detection function. Before an application is operated, the application is moved to an SRAM (Static Random Access Memory) from FLASH, the PC (Program Counter) pointer of a CPU (Central Processing Unit) is endowed with the first line of instruction address of the application, and one guidance function module operated by the application is started. By use of the program guidance method, before the application is transported, the SRAM operated by the application is checked, application transportation correctness is checked, and an operation target and the correctness of the operation environment of the operation target are guaranteed before the application is operated. By use of the method, through program uploading consistency checkout and checkout before and after transportation, correctness from a source program to the operation of the program each time is guaranteed, the function of the operation environment is guaranteed to be complete, and fault positioning can be quickly carried out once a program fails.
Description
technical field [0001] The invention relates to a method for guiding an SoC application program with a self-check function, and belongs to the technical field of SoC loading. Background technique [0002] SoC, the abbreviation of System on Chip, is the system on a chip. In a narrow sense, it is the chip integration at the core of an information system, which integrates the key components of the system on a chip; in a broad sense, SoC is a micro-miniature system. , Heart, Eye And Hand Systems. Academic circles at home and abroad generally tend to define SoC as the integration of microprocessor, analog IP core, digital IP core and memory (or off-chip storage control interface) on a single chip, which is usually customized by customers or for specific purposes standard products. Due to its strong scalability and high integration, SoC is widely used in mobile electronic products, smart devices and control devices. If the SoC is compared to the body, then the embedded softwar...
