接下来，详细介绍本发明实施例所提供的一种远程升级CPLD固件的方法。图1为本发明实施例提供的一种远程升级CPLD固件的方法的流程图，该方法包括：Next, a method for remotely upgrading CPLD firmware provided by an embodiment of the present invention is introduced in detail. Fig. 1 is a flow chart of a method for remotely upgrading CPLD firmware provided by an embodiment of the present invention, the method comprising:
S101：接收用户终端传输的镜像文件。S101: Receive the image file transmitted by the user terminal.
基板管理控制器(Baseboard Management Controller，BMC)，可以实现服务器的远程管理控制。BMC和服务器上的CPLD可以进行通信。A baseboard management controller (Baseboard Management Controller, BMC) can implement remote management and control of the server. The BMC and the CPLD on the server can communicate.
在本发明实施例中，用户终端利用BMC实现对CPLD固件的远程升级控制。In the embodiment of the present invention, the user terminal uses the BMC to implement remote upgrade control of the CPLD firmware.
在本地系统即用户终端上通过文件传输工具，例如CURL命令行工具获取远端BMC的登录权限。用户终端获取BMC的登录权限后，便可以与该BMC进行信息的交互。On the local system, that is, the user terminal, use a file transfer tool, such as the CURL command-line tool, to obtain the login permission of the remote BMC. After obtaining the login authority of the BMC, the user terminal can exchange information with the BMC.
在具体实现中，用户终端依据BMC对应的IP地址，实现与BMC的交互。每个BMC有其对应的IP地址，在CURL命令行中输入不同的IP地址，便可以与该IP地址对应的BMC实现通信。In a specific implementation, the user terminal realizes the interaction with the BMC according to the IP address corresponding to the BMC. Each BMC has its corresponding IP address. Enter a different IP address in the CURL command line to communicate with the BMC corresponding to the IP address.
用户在CURL命令行中输入多个IP地址，便可以获取相应的多个BMC的登录权限，实现用户终端和多个BMC的交互。每个BMC和其对应的一个CPLD具有通信连接，故此，用户终端可以实现对多个CPLD的远程控制，从而可以实现对多台服务器主板CPLD固件的批量升级。为了便于介绍，后续内容中均以用户终端和一个BMC通信为例展开说明。By entering multiple IP addresses in the CURL command line, the user can obtain the login authority of the corresponding multiple BMCs, realizing the interaction between the user terminal and multiple BMCs. Each BMC has a communication connection with its corresponding CPLD. Therefore, the user terminal can realize remote control of multiple CPLDs, thereby realizing batch upgrade of CPLD firmware of multiple server motherboards. For ease of introduction, the communication between a user terminal and a BMC is taken as an example in the following content.
用户终端存储有用于实现CPLD固件升级的镜像文件，用户终端可以通过CURL命令行工具将镜像文件上传至BMC。The user terminal stores an image file for upgrading the CPLD firmware, and the user terminal can upload the image file to the BMC through the CURL command line tool.
S102：对所述镜像文件进行解析，得到目标数据。S102: Analyzing the image file to obtain target data.
在镜像文件中包含有实现CPLD固件升级所需使用的数据，为方便介绍，可以将这些数据称作目标数据。在镜像文件中除了包含有目标数据外，还包含有一些其它的数据，为了实现CPLD固件的升级，需要从镜像文件中提取出目标数据。在本发明实施例中，BMC对镜像文件进行解析，从而获取所需的目标数据。The image file contains the data needed to implement the CPLD firmware upgrade. For the convenience of introduction, these data can be called target data. In addition to the target data, the image file also contains some other data. In order to upgrade the CPLD firmware, the target data needs to be extracted from the image file. In the embodiment of the present invention, the BMC parses the image file, so as to obtain the required target data.
举例说明，BMC可以在接收到用户终端传输的镜像文件时，直接对该镜像文件进行解析。BMC也可以在接收到用户终端发送的CPLD升级指令后，对镜像文件进行解析。For example, when the BMC receives the image file transmitted by the user terminal, it can directly analyze the image file. The BMC can also analyze the image file after receiving the CPLD upgrade instruction sent by the user terminal.
其中，用户终端可以通过CURL命令行工具向BMC发送CPLD升级指令。Wherein, the user terminal can send the CPLD upgrade command to the BMC through the CURL command line tool.
以用户终端向BMC发送CPLD升级指令为例，在具体实现中，用户终端通过CURL命令行工具向BMC发送镜像文件，此时BMC可以保存接收到的镜像文件。当需要对服务器主板CPLD固件进行升级时，用户终端再通过CURL命令行工具向BMC发送CPLD升级指令，BMC接收到CPLD升级指令时，对保存的镜像文件进行解析。Taking the user terminal sending a CPLD upgrade command to the BMC as an example, in a specific implementation, the user terminal sends the image file to the BMC through the CURL command line tool, and the BMC can save the received image file at this time. When the CPLD firmware of the server mainboard needs to be upgraded, the user terminal sends the CPLD upgrade command to the BMC through the CURL command line tool, and the BMC analyzes the saved image file when receiving the CPLD upgrade command.
S103：将所述目标数据发送给CPLD，以实现CPLD固件的升级。S103: Send the target data to the CPLD, so as to upgrade the firmware of the CPLD.
BMC获取到目标数据后，可以利用通用输入/输出口(General Purpose InputOutput，GPIO)模拟国际标准测试协议(Joint Test Action Group，JTAG)的方式进行数据的传输，将目标数据传输给CPLD。CPLD依据接收到的目标数据，便可以完成CPLD固件的升级。After the BMC acquires the target data, it can use the general purpose input/output port (General Purpose Input Output, GPIO) to simulate the international standard test protocol (Joint Test Action Group, JTAG) to transmit the data, and transmit the target data to the CPLD. The CPLD can complete the upgrade of the CPLD firmware according to the received target data.
由上述技术方案可以看出，BMC接收用户终端传输的镜像文件；对所述镜像文件进行解析，得到目标数据；该目标数据是完成CPLD固件升级所需使用的数据，BMC将所述目标数据发送给CPLD，CPLD依据接收到的目标数据，便可以实现CPLD固件的升级。BMC和CPLD之间具有通信连接，用户终端通过向BMC传输镜像文件的方式，来实现CPLD固件的升级，达到了通过远程操作实现CPLD固件升级的目的。相比于通过治具进行CPLD固件升级的方式，在实际应用中通过远程操作的方式能够更加方便的维护CPLD固件升级。As can be seen from the above technical scheme, the BMC receives the image file transmitted by the user terminal; the image file is analyzed to obtain the target data; the target data is the data required to complete the CPLD firmware upgrade, and the BMC sends the target data To the CPLD, the CPLD can upgrade the CPLD firmware according to the received target data. There is a communication connection between the BMC and the CPLD, and the user terminal realizes the upgrade of the CPLD firmware by transmitting the image file to the BMC, and achieves the purpose of realizing the upgrade of the CPLD firmware through remote operation. Compared with the method of upgrading CPLD firmware through fixtures, in practical applications, it is more convenient to maintain CPLD firmware upgrades through remote operation.
在将镜像文件由用户终端传输至BMC的过程中，由于网络不稳定等原因，可能会存在镜像文件传输不完整的情况，当镜像文件出现损坏时会直接影响后续CPLD固件的升级。During the process of transferring the image file from the user terminal to the BMC, due to network instability and other reasons, the transfer of the image file may be incomplete. When the image file is damaged, it will directly affect the subsequent upgrade of the CPLD firmware.
为了保证镜像文件的完整性和正确性，在对镜像文件进行解析之前，可以先对其进行校验。当镜像文件通过校验后，可以该镜像文件保存至预设位置，例如存储到BMC的文件系统下，以便后续对通过校验的镜像文件进行解析。In order to ensure the integrity and correctness of the image file, before parsing the image file, it can be verified first. After the image file passes the verification, the image file can be saved to a preset location, for example, stored in the file system of the BMC, so that the image file that passes the verification can be analyzed later.
其中，对镜像文件的校验可以采用MD5校验工具，对镜像文件的完整性进行校验。Wherein, the verification of the mirror image file may use an MD5 verification tool to verify the integrity of the mirror image file.
考虑到不同产品类型其对应的镜像文件不尽相同，在校验过程中，可以对镜像文件的产品类型进行判断，为了区分不同的产品类型所对应的镜像文件，可以对镜像文件设置标识符。Considering that different product types correspond to different image files, during the verification process, the product type of the image file can be judged. In order to distinguish the image files corresponding to different product types, an identifier can be set for the image file.
例如，可以用数字进行标识，产品A对应的镜像文件，标识符设置为01，产品B对应的镜像文件，标识符设置为02，依次类推，对于不同的产品类型对应的镜像文件设置不同的标识符。For example, it can be identified by numbers. For the image file corresponding to product A, the identifier is set to 01, for the image file corresponding to product B, the identifier is set to 02, and so on. Set different identifiers for image files corresponding to different product types symbol.
在BMC对镜像文件的校验过程中，可能会存在未通过校验的镜像文件。当镜像文件未通过校验时则说明该镜像文件存在问题，为了保证顺利完成后续CPLD固件的升级，BMC需要重新获取该镜像文件。具体的，当所述镜像文件未通过校验时，BMC可以向所述用户终端发送反馈信息。During the verification process of the image file by the BMC, there may be some image files that fail the verification. If the image file fails to pass the verification, it means that there is a problem with the image file. In order to ensure the smooth completion of the subsequent CPLD firmware upgrade, the BMC needs to obtain the image file again. Specifically, when the image file fails the verification, the BMC may send feedback information to the user terminal.
反馈信息用于表示BMC接收到的镜像文件存在问题，用户终端接收到该反馈信息后，可以将相应的镜像文件重新发送给BMC。The feedback information is used to indicate that there is a problem with the image file received by the BMC. After receiving the feedback information, the user terminal can resend the corresponding image file to the BMC.
每个镜像文件有其对应的标识符，因此在反馈信息中可以携带有相应的标识符，以便于用户终端可以获知具体是哪种产品类型对应的镜像文件存在问题，从而有针对性的重新向BMC发送所需的镜像文件。Each image file has its corresponding identifier, so the corresponding identifier can be carried in the feedback information, so that the user terminal can know which product type corresponds to the image file that has a problem, so as to redirect the targeted BMC sends the required image files.
与用户终端向BMC传输镜像文件类似，由BMC向CPLD传输目标数据的过程中也可能存在目标数据损坏的问题。当目标数据存在问题时，CPLD将无法顺利完成CPLD固件的升级，故此，当CPLD依据目标数据无法完成CPLD固件的升级或者CPLD检测到目标数据存在问题时，CPLD可以向BMC发送数据获取请求，BMC接收到该数据获取请求时，可以依据所述数据获取请求中携带的标识符，向所述CPLD发送相应的目标数据。Similar to the transmission of the image file from the user terminal to the BMC, there may also be a problem of damage to the target data during the process of transmitting the target data from the BMC to the CPLD. When there is a problem with the target data, the CPLD will not be able to successfully upgrade the CPLD firmware. Therefore, when the CPLD cannot complete the upgrade of the CPLD firmware based on the target data or the CPLD detects a problem with the target data, the CPLD can send a data acquisition request to the BMC, and the BMC When the data acquisition request is received, corresponding target data may be sent to the CPLD according to the identifier carried in the data acquisition request.
对一个镜像文件进行解析后，可以获取相应的目标数据。不同类型的镜像文件，其对应的目标数据不尽相同。BMC依据标识符可以获知是哪个镜像文件的目标数据存在问题，以便于具有针对性的向CPLD传输所需的目标数据。After parsing an image file, the corresponding target data can be obtained. Different types of image files have different corresponding target data. According to the identifier, the BMC can know which image file has a problem with the target data, so as to transmit the required target data to the CPLD in a targeted manner.
当服务器主板的CPLD完成CPLD固件的升级后，为了便于用户终端获知CPLD固件升级的完成情况，CPLD可以向BMC发送响应信息，BMC可以将接收到的响应信息转发至用户终端。该响应信息用于表示CPLD已经完成CPLD固件的升级。After the CPLD on the server main board completes the upgrade of the CPLD firmware, in order for the user terminal to know the completion of the CPLD firmware upgrade, the CPLD can send a response message to the BMC, and the BMC can forward the received response message to the user terminal. The response information is used to indicate that the CPLD has completed upgrading the CPLD firmware.
