Problems solved by technology

[0003] This approach has the following disadvantages: 1. Since all burning threads directly access files, this will cause a large number of file IO requests during the burning process and will cause thrashing in the external storage; 2. The burning data is not compressed and transmitted

Embodiment 1

[0072] Please refer to figure 1 , Figure 3 to Figure 5 , a firmware batch burning method, comprising steps:

[0073] S1. Obtain the data to be programmed, and lock the data to be programmed in the memory.

[0074] Specifically, the following data needs to be set and input before firmware batch programming:

[0075] The lower limit of the size of the burning block, the unit is sector, and one sector is 512 bytes. Since the flash storage is programmed to write data according to the page, it is preferable to set the lower limit of the burning block to 4 sectors, that is, one page size;

[0076] Erase block size, the unit is sector, it is recommended to set it to 512, 256k size;

[0077] The group size, in megabytes, is recommended to be set to 32;

[0078] The redundancy size at the end of the erase block, the unit is sector, it is recommended to set it to 128, which accounts for a quarter of the erase block size;

[0079] The upper limit of the burning block size, the uni...

Embodiment 2

[0106] Please refer to figure 2 , a firmware batch programming terminal, including a memory, a processor, and a computer program stored on the memory and operable on the processor, when the processor executes the computer program, the firmware of Embodiment 1 is realized The various steps of the batch programming method.

[0107] To sum up, the method and terminal for batch firmware programming provided by the present invention can obtain the data to be burned and lock the data to be burned in the memory, and can pre-write the burned data before data burning In the locked memory, prevent a large number of file IO operations during the burning process; according to the data content of the data to be burned, the data to be burned is divided into common blocks, repeated blocks, and erased blocks. The burning blocks are linked into a burning chain, and the burning chain is burned. If the common block is burned, the corresponding read and write data in the common block will be se...

Abstract

The invention discloses a firmware batch burning method and a terminal. The method comprise steps of obtaining and locking to-be-burnt data being in the memory, so as to prevent a large number of file IO operations from being generated in the burning process; dividing the to-be-burnt data into burning blocks of which the types are common blocks, repeated blocks and erasing blocks according to the data content of the to-be-burnt data, linking the burning blocks in the same group into a burning chain and carrying out burning, and if the common blocks are burnt, sending corresponding read-write data in the common blocks to a burning program for firmware burning; and if the repeated blocks are burnt, sending a burning address, a burning length and repeated data in the repeated blocks to a burning program for firmware burning, and if the erasing blocks are burnt, sending an erasure address and an erasure length in the erasing blocks to the burning program for firmware burning. The method is advantaged in that writing can be replaced by erasing to improve the burning speed, repeated blocks and erasing blocks do not need to transmit specific data, the data transmission amount sent to a burning program is reduced, and the firmware burning speed is improved.

Description

technical field [0001] The invention relates to the technical field of data burning, in particular to a firmware batch burning method and a terminal. Background technique [0002] At present, the main method of PC-based firmware batch programming is that the programming program will create a programming thread for each programming device. The programming thread is responsible for reading the programming data and transmitting it to the device through USB or serial ports. Notify the programming thread after the entry is successful, until the programming thread completes programming of all data. [0003] This approach has the following disadvantages: 1. Since all burning threads directly access files, this will cause a large number of file IO requests during the burning process and will cause thrashing in the external storage; 2. The burning data is not compressed and transmitted . Contents of the invention [0004] The technical problem to be solved by the present inventio...
