Detailed Description
In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
In the prior art, when parameter configuration is performed on an embedded product, firmware needs to be pre-compiled first, and the pre-compiled firmware is modified and repackaged, but the validity and the security of the firmware cannot be guaranteed.
In order to solve at least the above technical problem, the present disclosure provides a parameter configuration method. According to the method and the device, the configuration parameter partitions are added in the device partition table, the storage space of each parameter area is reserved in the configuration parameter partitions, the corresponding storage space is set according to the number of the parameter areas, and the storage space is initialized. The configuration parameters stored in each parameter area are stored in the corresponding storage space, so that the subsequent inquiry of different configuration parameters can be facilitated, and the initialization of the equipment is performed by using the configuration parameters in the storage space. In this way, embodiments in accordance with the present disclosure enable dynamic configuration of parameters without modifying the firmware itself.
Hereinafter, technical solutions according to the present disclosure will be described with reference to specific embodiments and with reference to the accompanying drawings.
Fig. 1 is a flow chart illustrating a parameter configuration method 100 according to an embodiment of the present disclosure. Referring to fig. 1, the method 100 includes the following steps 102 to 108.
In step 102, a partition table of a device is accessed to read a configuration parameter partition set in the partition table. The configuration parameter partition is used for storing all configuration parameters which need to be used in the device initialization process. The configuration parameter partition may include header information and a plurality of parameter areas. In some embodiments, the method 100 may further include adding the configuration parameter partition in a device partition table.
In step 104, the storage space corresponding to the parameter area is set according to the information associated with each parameter area in the configuration parameter partition. In some embodiments, the corresponding storage space is set according to the number of the parameter areas, and all the storage spaces are initialized. In some embodiments, a parameter area is determined according to header information in the configuration parameter partition, a corresponding storage space is reserved according to the determined parameter area, the size of the storage space is greater than or equal to the size of the configuration parameter partition, and the content of all the storage spaces is initialized to 0x 00. In this way, a corresponding large enough memory space can be provided for each parameter area, which is convenient for subsequent inquiry of different configuration parameters.
In step 106, if there is a configuration parameter in each parameter area in the configuration parameter partition, storing the configuration parameter in the storage space corresponding to the parameter area. In some embodiments, if the header information parameter of the configuration parameter partition is the same as a preset parameter, it is determined whether data exists in each of the parameter areas, and if so, the data in the parameter areas is stored in the corresponding storage space. In some embodiments, when the data in the parameter area is stored in the corresponding storage space, the offset address of the parameter area is located first, when the data in the parameter area is an encrypted ciphertext, the data is decrypted to a plaintext in the temporary buffer area and then copied into the storage space, and when the data in the parameter area is not the encrypted ciphertext, the data in the parameter area is directly copied into the corresponding storage space. In this way, any type of configuration parameters can be adaptively stored.
In step 108, the device is initialized according to the configuration parameters in the storage space. In some embodiments, it is determined whether data in the storage space is initialization data, and if not, the device is initialized by using the configuration parameters in the storage space. In some embodiments, the parameter regions include a trusted context parameter region, an encrypted parameter region, and an unencrypted parameter region. In some embodiments, it is determined whether data in the first storage space corresponding to the trusted environment parameter area is initialization data, if so, the device is initialized using default parameters, otherwise, the device is initialized using configuration parameters in the first storage space corresponding to the trusted environment parameter area. And then, judging whether the data in the second storage space corresponding to the encryption parameter area or the third storage space corresponding to the non-encryption parameter area is initialization data, if so, indicating that the corresponding second storage space or the corresponding third storage space is not used, otherwise, indicating that the corresponding second storage space or the corresponding storage space is used. In this way, the device can be initialized adaptively, the use condition of the corresponding second storage space or the third storage space is marked, and resource waste caused by subsequent frequent query is avoided.
In some embodiments, when initializing the peripheral device driver of the device, if the configuration parameter required by the peripheral device driver is located in the encrypted parameter area or the unencrypted parameter area, when the corresponding second storage space or the third storage space is marked as used, the configuration parameter is read from the second storage space or the third storage space to initialize the peripheral device driver, and the address and the length of the second storage space or the third storage space are transmitted to the kernel. In this way, the initialization of the dynamic parameters can be performed for the peripheral.
In some embodiments, when initializing a device kernel, the device enters a mirror mode, if a configuration parameter required for kernel initialization is located in an encryption parameter area or a non-encryption parameter area, when the encryption parameter area or the non-encryption parameter area is available, a physical address space of a corresponding second storage space or a corresponding third storage space is mapped to a virtual address space, a configuration parameter in the virtual address space is obtained, and the kernel is initialized. In this way, the kernel can be initialized with dynamic parameters.
In some embodiments, when initializing the user space, if the header information parameter of the configuration parameter partition is the same as the preset parameter and the configuration parameter required for initializing the user space is located in the encryption parameter area, determining whether the data exists in the encryption parameter area, if so, locating the offset address of the encryption parameter area, reading the data in the encryption parameter area into a temporary buffer area, and initializing the user space according to the configuration parameter in the plaintext after decrypting the data in the temporary buffer area into the plaintext. If the head information parameter of the configuration parameter partition is the same as the preset parameter and the configuration parameter required by user space initialization is located in the non-encryption parameter area, judging whether the non-encryption parameter area contains data or not, if so, locating to the offset address of the non-encryption parameter area, and initializing the user space according to the data of the non-encryption parameter area. In this way, the initialization of dynamic parameters for the user space is enabled.
Hereinafter, an application scenario of the parameter configuration upgrade method according to the embodiment of the present invention will be described by way of example.

The configuration parameters are converted into a binary mirror image file which is written into the configuration parameter partition of the equipment through a burning tool before leaving the factory.
In some embodiments, the size of the binary image file corresponding to the configuration parameter is consistent with the size of the configuration parameter partition, and if the total size of all the configuration parameter information is smaller than the size of the configuration parameter partition in the process of generating the configuration file binary image file, 0x00 is filled at the end until the size of the entire binary image file is consistent with the size of the configuration parameter partition.
In addition, the binary image file corresponding to the configuration parameters includes 4 parts, which are fixed-size image header information, a trusted environment parameter area, an encrypted parameter area, and an unencrypted parameter area, respectively.

The non-encryption parameter area stores all configuration parameters except configuration parameters needing encryption in boot program configuration parameters, kernel space configuration parameters and user space configuration parameters.
In step 204, the device is started, and in the boot program starting, the partition table of the device is accessed first, and the starting address and the length of the configuration parameter partition are obtained; then, three storage spaces with at least the size of the parameter partition are reserved in the DDR memory of the device, and all the storage spaces are initialized to 0x 00. These three reserved memory spaces cannot be used for subsequent allocations. Step 204 includes the following steps 2042 to 2048.
In step 2042, the fixed-size header information of the configuration parameter partition is read, whether the magic number of the configuration file is consistent with the expected magic number is checked, and if not, step 206 is executed. If so, execution continues at step 2044.
In step 2044, the trusted environment parameter area offset address and the trusted environment parameter area length in the header information are read, if the trusted environment parameter area length is 0, step 206 is executed, otherwise, the trusted environment parameter area offset address of the configuration parameter partition is located, data of the trusted environment parameter area length is read to the temporary buffer area, the ciphertext in the temporary buffer area is decrypted by using a built-in symmetric encryption algorithm and a key, and finally the decrypted plaintext is copied to the reserved storage space 1.
In step 2046, the offset address of the encryption parameter area and the length of the encryption parameter area in the header information are read, if the length of the encryption parameter area is 0, step 2048 is executed, otherwise, the offset address of the encryption parameter area of the configuration parameter partition is located, data of the length of the encryption parameter area is read to a temporary buffer area, a ciphertext in the temporary buffer area is decrypted by using a built-in symmetric encryption algorithm and a key, and finally the decrypted plaintext is copied to the reserved storage space 2.
In step 2048, the unencrypted parameter area offset address and the unencrypted parameter area length in the header information are read, if the unencrypted parameter area length is not 0, the unencrypted parameter area offset address is located in the configuration parameter partition, and the data of the unencrypted parameter area length is read to the reserved storage space 3.
In step 206, the boot program is started to load the trusted operating system, whether all the reserved storage spaces 1 are 0x00 is checked in the trusted operating system, and if yes, the initialization of the trusted operating system, the secure peripheral and the available application is completed by using default parameters; otherwise, the expected configuration parameters are read from the reserved memory space 1 to complete the initialization of the trusted operating system, the secure peripheral and the available applications.
In step 208, the boot loader checks the reserved 2 and 3 memory spaces to see if all the data in the memory space is 0x00, if so, the memory space is marked as unused, otherwise, the memory space is marked as used.

If the reserved memory space 2 is marked as unused, the initialization of the corresponding module and the peripheral is completed using default parameters.
In step 3024, if the configuration parameters are located in the unencrypted parameter area, the reserved memory space 3 is checked, and if the reserved memory space 3 is marked as used, the expected boot configuration parameters are read from the reserved memory space 3 to complete the initialization configuration, and the starting physical address and length of the reserved memory space 3 are passed to the kernel (e.g., shared _ param _ addr and shared _ param _ len) via the command line parameters.
