高通鏡像文件分包方法

文檔說明

本文檔以SC826(MSM8953平臺，Android 7)爲例，描述如何對SOC鏡像文件分包。

應用背景

客戶用QFIL刷固件的時候，由於客戶自己編譯生成的固件是沒有經過分包的，燒錄耗時較久。如果將編譯生成的固件先分包後，再燒錄就可以提升燒錄效率。

分包準備工作

1. 準備分包腳本checksparse.py

#!/usr/bin/python
#===========================================================================

#  This script parses "rawprogram.xml" looking for sparse="true" tags
#  if found, it tries to find the sparse files and updates rawprogram.xml
#  such that msp.py, T32 and QPST can program them
