helloworld_fel 使用了 VFP 寄存器参数，但是某个库文件(libgcc.a(_udivmoddi4.o))却不支持。
-
缺少 .note.GNU-stack 段，暗示可执行栈缺失。
-
对于具有 RWX 权限的 LOAD 段，给出了警告。
-
在链接时，出现了对 raise 函数的未定义引用。

回复: T113S3双路 dual lvds驱动不起来发布在 T Series
uboot和dtsi里面添加dual link IO的配置

&lcd0{ ... lcd_lvds_if = <1>; ... ... pinctrl-0 = <&lvds2link_pins_a>; pinctrl-1 = <&lvds2link_pins_b>; ... }其他和single link的配置方法无异，如果点不亮请检查时序
这里看到dclk配置是80
但是手册需求的是54
这里提供一套1920x720的时序作为参考

回复: v853 vin通路配置发布在 V Series
（1）在线模式：四个vipp和dma实体，最大缩小比例为16*16，每路最多可支持16个orl
（2）离线模式：每个vipp和dma可分时复用为4个vipp和dma虚拟体，四个vipp和dma实体相互独立，在线模式和离线模式开关也是相互独立的；
（3）VIPP和DAM的分时复用（离线模式）与isp和tdm的分时复用（离线模式）是绑定关系，即tdm和isp开启了离线模式，vipp和dma的输入端如果是isp，那么vipp和dma也需要开启离线模式；
（4）只有VIPP0和dma0实体支持VE在线编码，而vipp0在线，如果vipp00的输入端为isp，那么tdm和isp也只能配置在线模式，而isp在线，那么四个vipp和dma实体都只能配置在线模式；online 和 offline 配 置 方 式 在 board.dts ， 所 以 需 要 在 对 应 版 型 的 board.dts 中 找 到 vind0 节 点 配 置 列 表 ， 对 应 关 系 为 tdm 对 应 节 点 ， isp 对 应 isp00 节 点 ， vipp 对 应 scaler00 、 scaler10 、 scaler20 和 scaler30 节 点 ， dma 对 ， 应 vinc00 、 vinc10 、 vinc20 和 vinc30 节 点 。
- 在线模式，单路3输出
- 离线模式，2路8输出

IMX219 同样可以使用，但是请注意4lane的摄像头不可适配2lane的数据
