这里主要以裸分区为例比如oem分区。 1、创建一个1MB大小的oem.img写入内容“test oem partition” 创建方式
dd if/dev/null ofoem.img bs1024 count1oem.img内容 2、XBL阶段读分区方案 2.1、创建oem_partition_id 在https://www.guidgenerator.com/online-guid-generator.aspx网站自动生成生成后加入boot_images/QcomPkg/XBLLoader/boot_gpt_partition_id.c文件
diff --git a/BOOT.XF.4.1/boot_images/QcomPkg/XBLLoader/boot_gpt_partition_id.c b/BOOT.XF.4.1/boot_images/QcomPkg/XBLLoader/boot_gpt_partition_id.c
