Embodiment
Below in conjunction with embodiment the present invention is further described:
According to the design of NodeB system, the commencement of commercial operation software of intrasystem peripheral single board all leaves in the CF card of master control veneer BMC, and peripheral single board is by certain protocol and BMC communication, with each software download in internal memory separately, and with its startup.The present invention has then proposed a kind of processing scheme of downloading software and guiding startup and remote upgrade from BMC.Because the veneer of NodeB adopts embedded OS usually, and starts by BOOT ROM, so whole software can be divided into two parts: ROM start-up system and system's commencement of commercial operation.Wherein to start the function of software be the guiding single board starting to ROM and download formal software to specified memory, and the software that commencement of commercial operation software moves when being only whole normal working of single board.
After ROM powers on, program among the ROM is to the software download of BMC application veneer, and BMC wants downloaded software according to applicant's information decision, and the file transfer protocol (FTP) by veneer and BMC downloads software among the RAM of veneer, according to the characteristics of specific operating system, move the software of downloading then.Stored needed current operating software of all peripheral single board and backup software on the CF card of BMC plate, and with relevant information records at lane database.After peripheral single board powered on, the software in the peripheral single board BOOT ROM was applied for software download to BMC, and BMC needing to obtain the downloaded software specifying information and sends to the applicant according to applicant's information inquiry database.Then, by the file transfer protocol (FTP) between BMC and the peripheral single board software download is arrived in the internal memory of peripheral single board.
When software need be upgraded, remote control terminal notice BMC, file transfer protocol (FTP) by appointment after BMC responds downloads to software on the CF from remote control terminal, increases relevant record then and it is masked as backup in database, downloads successfully back BMC notice remote control terminal.The user can activate upgrading software by remote control terminal, BMC changes being masked as by backup of the related software in the database into operation after receiving activation command, the software of original running status is changed into Status of Backups, and BMC sends reset message to peripheral single board then.Veneer can restart after receiving reset message, and BOOT ROM powers on the back to BMC application software download, and the BMC Query Database goes the software download that is masked as operation to veneer.
Below by an example the present invention is described further: in example of the present invention, the user by daemon software BBP (Node B Base-band Processing, LTE Baseband Processing Unit) board software is downloaded on the CF card of BMC, is downloaded to from BMC by the BBP plate then again and goes the internal memory and start execution.In example, the used operating system of veneer is VxWorks, veneer and BMC adopt TCP/IP (Transfer Control Protocol, transmission control protocol/Internet Protocol, Internet protocol) agreement, file transfer adopts FTP (FileTransfer Protocol, file transfer protocol (FTP)) agreement.In fact, though embodiment adopts said system and agreement, in the system and agreement of other types, the method for the invention stands good.
Fig. 3 is the memory allocation map of vxworks operating system, and in VxWorks, after system powered on, processor began to carry out romInit (), and this program inhibition interrupts, and will start type (cold/heat) pop down, jumps to romStart () after doing the relevant hardware initialization.In romStart (), reflection among the system loads ROM is in RAM, if the reflection of the VxWorks among the ROM is a compressed version, then system carries the block among the ROM and data segment on the arm shellfish and unzips among the RAM, be positioned at RAM_HIGH_ADRS, jump to this address then and in RAM, carry out the remaining program of ROM.Because can being divided into ROM, whole software starts software and two parts of commencement of commercial operation.ROM starts the ROM program form (vxWorks_romCompress) that software is compression, and commencement of commercial operation software then is to exist with the binary file form.RAM_LOW_ADRS among Fig. 3 is that the BIN file of VxWorks acquiescence is carried out inlet, therefore the RAM_LOW_ADRS in the commencement of commercial operation software that generates the BIN file must with the BOOT program in to deposit the address of the formal software under the download consistent.
Conflict with the internal memory of depositing rom software for fear of the internal memory of depositing the formal software of downloading, the present invention is revised as the Memory Allocation of startup software among the ROM and formal software shown in Figure 4.In Fig. 4, the BOOTStartAddr that ROM starts software is a memory address of depositing the formal software of downloading, and it equals the RAM_LOW_ADRS in the formal software physically.Equally, the RAM_LOW_ADRS in the ROM startup software equals the RAM_HIGH_ADRS in the formal software.Like this, start the formal software download of software handle behind BOOTStartAddr at ROM, jump to when formal software is carried out in this address and redefine RAM_LOW_ADRS and RAM_HIGH_ADRS, be equivalent to directly jump to RAM_LOW_ADRS, thereby can normally move formal software.Program among the ROM and the formal loading of software in RAM are as shown in Figure 5.
Introduce whole example process in detail below in conjunction with embodiment.
