[RK3288][Android6.0] 调试笔记 --- user版本固件升级无法开机问题

Platform: ROCKCHIP

OS: Android 6.0

Kernel: 3.10.92

这个是我同事解决的问题,不是我哈,也分享给大家~

user版sd固件升级启动之后开机出现如下error log:

原因:

system分区默认是512M

RKTools/linux/Linux_Pack_Firmware/rockdev/parameter:

0x00100000@0x00092000(system)

0x00100000,单位是512.

而user版本编译出来的system分区大小超过了512M

解决方法:

扩大system分区.
