Technical Field
The invention relates to a data processing technology, in particular to a method for on-line upgrading of multi-board software.
Background
At present, most project software upgrading is still carried out in a programmer mode, and the biggest defect is that a cover needs to be opened for each upgrading, and the efficiency is low. A few projects began to be upgraded online, typically using SDFlash recommended by TI or C2Prog by CodeSkin. The two tools support more DSP models and have more powerful functions. The method has the disadvantages that errors are made in the midway, the problem is difficult to find according to the prompt, and the multi-board system is not supported to be upgraded. To use the above two types of upgrade software, it is necessary to control each board individually and to lead out the serial line of each board. The actual project situation is more complicated, a serial port line is designed and led out only when a board which needs to report data outwards is involved, and other boards do not directly send data outwards. Upgrading of multi-board software cannot be accomplished using common tools.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a method for on-line upgrading of multi-board software aiming at the defects in the prior art.
The technical scheme adopted by the invention for solving the technical problems is as follows: a method for multi-board software online upgrade comprises the following steps:
1) a state information board is arranged between the upper computer and the plurality of monitoring operation boards to be upgraded; the state information board is communicated with the upper computer through an SCI (serial peripheral interface), and the state information board is communicated with the monitoring operation board through an SPI (serial peripheral interface); codes for unlocking Flash and receiving data are solidified in the state information board and the monitoring operation board;
2) the upper computer is powered on firstly and continuously sends an upgrading command to the state information board;
3) after the state information board is powered on, after the state information board and the monitoring operation board are initialized, the state information board detects whether an upgrading instruction exists;
4) after the state information board detects the upgrading instruction, the upgrading instruction is sequentially sent to the monitoring operation board through SPI communication, and the information which is fed back by the monitoring operation board and receives the upgrading instruction is received to the state information board;
5) the state information board reports the upgrading preparation of the monitoring operation board to the upper computer through SCI communication;
6) the state information board receives the segmented upgrading codes of the monitoring operation boards analyzed by the upper computer, and the codes are packaged and then sent to the monitoring operation boards; the method comprises the following specific steps:
the upper computer sends the first section of the upgrading code of the monitoring operation board to the state information board, the state information board packages the first section of the upgrading code according to the SPI format and then sends the first section of the upgrading code to the first state information board, and after receiving the feedback that the first state information board finishes programming the first section of the code, the state information board feeds back the first section of the upgrading code to the upper computer to be finished and then sends the first section of the upgrading code to the subsequent monitoring operation board; if not, the state information board starts a retransmission to the uncompleted monitoring operation board;
7) judging whether all the segmented codes of each monitoring operation board are finished or not, if so, finishing upgrading of the monitoring operation board, and otherwise, repeating the step 6);
8) and the upper computer sends the upgrading code of the state information to the state information board through the serial port in a sectional sending mode, and after the state information board is finished, the upper computer feeds back the completion of upgrading.
The invention has the following beneficial effects:
the invention designs a method for upgrading multi-board software on line aiming at the limitation that the common upgrading software can only upgrade single-board software, thereby avoiding the situation that the single-board upgrading software needs to be externally connected with a controller to control the current upgraded board, and the upgrading of all boards can be completed by one key of an upper computer, and the upgrading efficiency is high.
