有没哪位同仁做过屏的的cmd模式转vdo模式的？
请将你的
static void lcm_get_params(LCM_PARAMS *params)
发上来给大家看看
怀疑 是这个东西配置有问题。
我在75与89上都没有做过MIPI所以不清楚
在72上做MIPI接口的，没有你说的问题。
这个是75上的，用的屏是科迪的 fwvga，IC ili9806

你的初始化中有没有一个0X35的寄存器?
89平台上点的那个屏没有,75点的屏上面有,这和TE有关么?
最好关掉吧。
ok
试试看
试了下 关掉也没用
发个log上来看看，开机黑屏
lcd背光亮了吗? 另外既然你唤醒可以，那你可以看看你resume干了些什么?
背光 亮了 在cmd模式下是ok的
小编：请教下，下面这两个参数是配置什么的，刚接触屏调试，不太懂；
params->dsi.vertical_sync_active = 4;
params->dsi.horizontal_sync_active = 6;
水平和垂直同步信号脉冲宽度
嗯嗯，学习了，非常感谢！
请问 params->dsi.mode = BURST_VDO_MODE;跟params->dsi.mode = SYNC_PULSE_VDO_MODE;有什么区别，怎么确定该填哪个值。
小编，请问你这个问题解决了吗，如果解决了能否告知是如何解决的?
