Abstract
The invention provides a microwave remote outdoor unit (ODU) software updating method, in advance writing Boot into the ODU, downloading target code through indoor unit (IDU) to the MCU of the ODU so as to achieve updating. And the invention divides application software into Boot and Firmware, flexible to apply, and thus people can update source code Firmware through remote network or microwave, and it is especially suitable to update software part of products in adverse environments.
Description
Technical field
The present invention relates to a kind of update method of software, particularly a kind of update method of microwave remote outdoor unit software.
Background technology
Because communication product outdoor unit ODU is that frame is on the brandreth in high-altitude, the abominable high-altitude of product in to(for) encapsulation upgrades application program Firmware if desired, edit the importing hexadecimal code S.19 by compiler BDM or Cyclone Pro, need open the screw and the lid of shell, insert the BDM data line, needing to carry on the notebook brandreth in high-altitude simultaneously, to remove to implement down loading updating application program Firmware be the comparison difficulty.If before dispatching from the factory, Boot is write earlier in the outdoor unit ODU, in the outdoor unit ODU Boot has been arranged as long as guarantee, then only need control indoor unit IDU down loading updating application program Firmware, object code is passed through indoor unit IDU down loading updating in the MCU of outdoor unit ODU, thereby reach the purpose of renewal.
Summary of the invention
Technical matters of the present invention is to provide a kind of microwave remote to download the method for carrying out software upgrading.
In order to solve above technical matters, the invention provides a kind of update method of microwave remote outdoor unit software, its job step is as follows:
1) outdoor unit ODU power supply;
2) code of needs renewal Firmware redaction is uploaded to indoor unit IDU.
3) pointer of the controller MCU of outdoor unit ODU jumps to the start address of Boot, and the version number of reading outdoor unit ODU from EEPROM is uploaded to indoor unit IDU with version number;
4) indoor unit IDU judges whether it is update command according to version number; Not, redirect the 13rd) step;
5) if indoor unit IDU replys is update command, then download initializes order;
6) wipe Flash fixed page and paging;
7) outdoor unit ODU makes initialization for indoor unit IDU to reply;
8) one group of data of reception indoor unit IDU;
9) form array;
10) judge whether the array that receives is correct; Not, response for indoor unit IDU and wait for repeating transmission; Redirect the 8th) step;
11) judge whether these frame data that receive are end frame; Be redirect the 13rd) step;
12) frame data have been write; Make which frame reception for indoor unit IDU and reply back wait reception next frame data; Jump to the 8th) step;
13) jump to the start address of application program Firmware, beginning executive utility Firmware;
14) finish.
The wiping of Flash fixed page and paging is divided into part and wipes with piece and wipe.Part is wiped and is meant and once can wipes 512 bytes; It is that the call instruction word once can be wiped the 64K byte content that piece is wiped.For the erase operation of most of chip fixed pages, need carry out erase operation to code copy to the Ram district.
Writing of Flash fixed page and paging is meant the operation of writing for most of chip fixed pages, need carry out erase operation to code copy to the Ram district.
Superior effect of the present invention is: the present invention is divided into two application software, promptly be divided into Boot and Firmware two parts, applying flexible, that we need upgrade usually is Firmware, we can just can upgrade source code Firmware by telecommunication network or microwave like this, are particularly suitable for the renewal of the software section of rugged surroundings product.
Description of drawings
Accompanying drawing is a workflow diagram of the present invention.
Embodiment
See also shown in the accompanying drawing, the present invention is done to describe further.
Because the edition upgrading of Firmware, need to upgrade the version of Firmware in the outdoor unit ODU now, the needs in the indoor unit IDU upgrade application version and number are: 00.00.01.02.
The application code of Boot is stored in the fixed page 3F of MCU, and (0xC000～0xFFFF), the code that is downloaded Firmware are stored in fixed page 3E (in the page or leaf of 0x4000～0x7FFF) and paging Block1, Block2, the Block3.The start address of Boot is stored in: 0x0FFFE; The start address of Firmware is stored in: 0x7FFFE.Its job step is:
1) gives the power supply of outdoor unit ODU and indoor unit IDU line;
2) code of needs renewal Firmware redaction 00.00.01.02 is uploaded to indoor unit IDU.
3) pointer of the controller MCU of outdoor unit ODU directly jumps to the start address 0x0FFFE of Boot (what deposit is start address: 0xC000), carry out the application program of Boot;
4) after the Boot program initialization, the data that at first begin to read continuous four unit from the 0x0B00 address of EEPROM are former Firmware version number: 00.00.01.01 is uploaded to indoor unit IDU, waits for the response of indoor unit IDU;
5) deposit needs in the version number that reports according to outdoor unit ODU of indoor unit IDU and the indoor unit IDU and upgrade Firmware version number: the 00.00.01.02 version compares, because the version number that will upgrade is higher, then need to upgrade, what indoor unit IDU replied is update command: the download initializes order;
6) outdoor unit ODU receives that the download initializes order needs down loading updating, rather than redirect Skip order, then wipes 3E (page or leaf of 0x4000～0x7FFF) and paging Block1, Block2, Block3;
7) wipe clean back outdoor unit ODU response indoor unit IDU, prepare to receive the frame data that indoor unit IDU sends;
8) receive frame data that indoor unit IDU sends and form array;
9) whether the array that judge to receive is correct, if incorrect then do not response through these frame data of check, wait for and retransmits these frame data; Jump to the 8th) step;
10) judge whether these frame data that receive are end frame, are to jump to the 12nd) step;
11) write frame data after, make and correctly reply and jump to the 8th) step;
12) jump to the start address of application program Firmware: 0x7FFE, beginning executive utility Firmware;
13) finish.
Claims (1)
1, a kind of update method of microwave remote outdoor unit software is characterized in that following job step:
1) outdoor unit ODU power supply;
2) code of needs renewal Firmware redaction is uploaded to indoor unit IDU.
3) pointer of the controller MCU of outdoor unit ODU jumps to the start address of Boot, and the version number of reading outdoor unit ODU from EEPROM is uploaded to indoor unit IDU with version number;
4) indoor unit IDU judges whether it is update command according to version number; Not, redirect the 13rd) step;
5) if indoor unit IDU replys is update command, then download initializes order;
6) wipe Flash fixed page and paging;
7) outdoor unit ODU makes initialization for indoor unit IDU to reply;
8) one group of data of reception indoor unit IDU;
9) form array;
10) judge whether the array that receives is correct; Not, response for indoor unit IDU and wait for repeating transmission; Redirect the 8th) step;
11) judge whether these frame data that receive are end frame; Be redirect the 13rd) step;
12) frame data have been write; Make which frame reception for indoor unit IDU and reply back wait reception next frame data; Jump to the 8th) step;
13) jump to the start address of application program Firmware, beginning executive utility Firmware;
