Description

一种提高系统固件烧写速度的方法 技术领域
本发明属于半导体领域，尤其涉及一种提高系统固件烧写速度的方法。
背景技术
系统固件(ROM)是指固化的软件，它把某个系统程序写入到特定硬件系统中的闪存。手机固件相当于手机的系统，刷新固件就相当于刷系统。
系统程序首先生成系统镜像，然后将系统镜像传输到设备的内存中烧写到设备的闪存。以系统程序system为例，为了能满足用户在使用过程中添加新的数据信息，系统程序system生成系统镜像大小通常要远大于系统程system大小，比如500M的系统程序，可能需要制作出1G甚至更大的系统镜像system.img，这就导致系统固件非常大，使得制作镜像耗时多并且将制作好的镜像烧写到硬件上速度也很慢。
现有技术中为了提高系统固件的烧写速度，一些厂商采用将带有系统文件的可存储数据空间的系统中间文件先压缩，然后根据压缩后的中间文件系统生成系统镜像，再传输到内存，此方法在很大程度上加快了传输到内存的速度，但是在最后将系统镜像烧写到设备闪存前需对制作生成的系统镜像采取解压操作，然后将解压后的系统镜像烧 写到闪存，这个过程也很耗时。因此，如何在其他性能不变的情况下有效缩短系统镜像的制作时间和将系统镜像烧写到硬件设备的时间，提高系统固件的烧写速度成为本领域技术人员面临的一大难题。
发明内容

实施方式
通过阅读参照以下附图对非限制性实施例所作的详细描述，本发明及其特征、外形和优点将会变得更加明显。在全部附图中相同的标记指示相同的部分。并未可以按照比例绘制附图，重点在于示出本发明的主旨。
针对系统固件烧写速度低烧写时间长的问题，本发明披露了一种提高系统固件烧写速度的方法，通过调整中间文件系统的大小，根据中间文件系统调整后的大小生成系统镜像，再将系统镜像传输到内存烧写到设备闪存，该方法有效减小了系统镜像的大小，节省了制作系统镜像的时间和将系统镜像传输到内存的时间以及将系统镜像烧写到闪存的时间，有效提高了系统固件的烧写速度，同时减少了工程师调试的时间，减少了产线上硬件生产的时间。下面结合附图和具体的实施例对本发明作进一步的说明，但是不作为本发明的限定。
系统固件是一个非常大的文件集合，比如Andriod系统中的system.img，userdata.img，ccache.img等，本实施例仅以system.img为例进行阐述，基于本发明原理的仅对系统中其他文件的改变同样属于本发明保护的范围。
参见图1所示现有技术中系统固件烧写过程流程图，以一个500M的system/目录为例进行阐述，以需要存500M的数据信息为例，由于有500M的文件系统，优选的，生成1024M的中间文件系统，所谓中间文件系统，其大小包含系统文件和容纳的数据容量，然后根据1024M的中间文件系统生成1024M的系统镜像文件system.img，再将制备好的1024M的系统镜像文件system.img传输到内存(实施 例中以智能设备为例)，也就是图1中所示的下载1G数据到内存，最后将传输到内存中的1G镜像文件system.img烧写到智能设备的闪存。500M的文件系统却要生成包含500M文件系统和需存储数据容量大小的中间文件系统，然后根据中间文件系统大小生成系统镜像，这无疑导致了系统镜像大，传输、烧写时间长的问题，现有技术中为了避免这一问题，先将生成的中间文件系统进行压缩，压缩后大大减小了中间系统文件的大小，然后将压缩后的中间文件系统传输到内存，烧写到设备闪存时需解压后烧写，这又将浪费很多时间，这里的设备包含手机和平板电脑。
参见图2所示提高系统固件烧写速度方法的流程图，首先调整中间文件系统的大小，然后根据中间文件系统调整后的大小生成相应的系统镜像，继续将生成的系统镜像传输到内存，最后执行将系统镜像烧写到设备内存。
参见图3所示结构，本发明烧写系统固件方法过程示意图，同样以500M文件系统制造成能容纳500M数据信息的闪存设备为优选的实施例。
根据常规做法，500M的文件系统生成1024M的中间文件系统，优选的，文件系统ext3，首先应用命令$resize2fs-M system.img将1G(1024M)的中间文件系统调整成只包含文件系统大小，即500M；作为另一个实施例，选择ntfs系统，当系统镜像system.img位于loop0设备，应用命令ntfsresize–b–s 516M/dev/sdf调整中间文件系统到516M。现有技术中成熟的文件系统都支持调整文件系统的大小(如 ext3/4，ntfs，fat)。根据中间文件系统调整后大小500M生成相应的系统镜像，值得注意的是，生成的系统镜像要稍微大于中间文件系统，以能容纳一些系统必需文件，根据不同的系统必需文件设置不同的大小，但是都在16M以内，即生成不大于516M的系统镜像。
将不大于516M的系统镜像传输到内存中，并烧写到设备的闪存，即完成系统固件的烧写，闪存设备包含但不仅限于手机和平板电脑。住的注意的是，首次启动时，需要调整烧写到闪存的系统固件到调整前中间文件系统的大小，以使其能容纳500M的数据信息。这里的调整也很好调整，作为一个实施例，当文件系统ext3生成的系统镜像system.ing位于sdf分区，应用命令$resize2fs/dev/sdf即可；当文件系统为ntfs时，应用命令ntfsresze–x/dev/sf将烧写后的系统硬件还原到中间文件系统大小。采用本方法提高了系统固件的烧写速度，有效缩短了系统固件烧写的时间，如将目前市面上流行的Andriod手机1.5G的系统镜像的中间文件系统调整到满足文件系统800M后，机器的烧写时间从118s降低到66s。
综上所述，本发明通过在生成系统镜像前调整中间文件系统的大小，然后根据中间文件系统的大小生成系统镜像，有效缩小了生成镜像的时间和将系统镜像传输到内存的时间以及烧写系统镜像到设备闪存的时间，有效缩短了将镜像烧写到硬件的时间，提高了系统固件的烧写速度。
本领域技术人员应该理解，本领域技术人员在结合现有技术以及上述实施例可以实现所述变化例，在此不做赘述。这样的变化例并不 影响本发明的实质内容，在此不予赘述。
以上对本发明的较佳实施例进行了描述。需要理解的是，本发明并不局限于上述特定实施方式，其中未尽详细描述的设备和结构应该理解为用本领域中的普通方式予以实施；任何熟悉本领域的技术人员，在不脱离本发明技术方案范围情况下，都可利用上述揭示的方法和技术内容对本发明技术方案作出许多可能的变动和修饰，或修改为等同变化的等效实施例，这并不影响本发明的实质内容。因此，凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所做的任何简单修改、等同变化及修饰，均仍属于本发明技术方案保护的范围内。
