[尚飞汤]

can anyone tell me how to slove??? i have do the patch of freescale.

[jimmychan]

sorry, I don't understand. which logo you want to change?

[尚飞汤]

i have changed the logo,and follow freescale's patch keep uboot logo to kernel.however, when show to the android logo(which we called third logo),the screen has a splash.

now,do understand?

[jimmychan]

which bsp are you using?

[jimmychan]

So, you want to keep the 'Android' logo? or not?

if not, please try to remove the bootanimation in the init.rc.

[尚飞汤]

no,

we have two logo,one is uboot logo,the other is the android logo,however when the uboot logo turn to be android logo,the screen has a flash which is so ungainly,can you tell me how to deal with it????

[qiang_li-mpu_se]

The issue should be caused by your modification on the patch, please list your modifications.

[尚飞汤]

Dear li：

     i attempt to change the patch to yours,but i find it is hold on the     kernel start........,can you give some tips?

they say that you are the master of this part .

[qiang_li-mpu_se]

What's your display config? LVDS panel on LVDS port 0? Are you use JB4.2.2 BSP?

[尚飞汤]

yes,lvds_num=0,but did that relation to the ipu di? I  think the ipu dix can transform for lvds0 and lvds1. did this right?

i was use JB4.2.2 .and what's the meaning of display config?

static struct fb_videomode ldb_modedb[] = {

  {

  "LDB-PAT215", 60, 1024, 768,15385,

  240, 48,

  23, 3,

  32, 12,

  0 ,

  FB_VMODE_NONINTERLACED,

  FB_MODE_IS_DETAILED,},

};

is this?

[qiang_li-mpu_se]

The LVDS0 example had been given in Patch to support uboot logo keep from uboot to kernel to Android for JB4.2.2_1.1.0-GA and L3.0.35_4....

Verified on both iMX6DQ and iMX6DL boards.

[尚飞汤]

Dear li：

I find when i ptach your patch，it will stop at do_register_framebuffer

fb_notifier_call_chain(FB_EVENT_FB_REGISTERED, &event);

and previous my colleague delete this code. she has resigned. i don't know how she did that,

so i porting her code to my project. but  my has ipu warning.

[qiang_li-mpu_se]

You should not change that code.

[尚飞汤]

嗨，Dear Li，porting了你给的uboot里面的代码，修改了LVDS_NUM=0;DISP_NUM=0;但是屏幕一直黑屏，量取了信号，发现信号线没有信号出来，其他时钟电压都是ok的，请问是否是因为该patch不支持LVDS0的配置？

[qiang_li-mpu_se]

LVDS0的例子也已经给了，porting的工作都不需要了，你只要直接打patch，然后修改你们的LVDS屏用的timing参数就可以了。

[尚飞汤]

嗨 li,我研究了你的patch，看你的patch在uboot里面应该默认就是支持LVDS1的吧，但是我这边是需要支持LVDS0，所以我顺便改了相应LVDS_NUM=0;DISP_NUM=0,应该是ok的吧，但是开启之后一直黑屏，所以想讨教下是否还需要改什么别的参数。

[qiang_li-mpu_se]

只要uboot头文件改LVDS_NUM=0;DISP_NUM=0，然后kernel编译时，也选成CONFIG_MX6_CLK_FOR_BOOTUI_TRANS_LVDS_IPU1_DI0，就好了。

[尚飞汤]

Dear li：

打了你的patch无法显示，我这边把所有之前和现在的patch全部拿掉，结果发现还是会出现ipu_warning.但是概率有所下降。

具体发现ipu_warning发生的地方是在：

mxcfb_set_par中的4.4——4.5之间

printk("[4]\n");

  ipu_clear_irq(mxc_fbi->ipu, mxc_fbi->ipu_ch_irq);

printk("[4.1]\n");

  ipu_disable_irq(mxc_fbi->ipu, mxc_fbi->ipu_ch_irq);

printk("[4.2]\n");

  ipu_clear_irq(mxc_fbi->ipu, mxc_fbi->ipu_ch_nf_irq);

printk("[4.3]\n");

  ipu_disable_irq(mxc_fbi->ipu, mxc_fbi->ipu_ch_nf_irq);

printk("[4.4]\n");

  ipu_disable_channel(mxc_fbi->ipu, mxc_fbi->ipu_ch, true);

printk("[4.5]\n");

  ipu_uninit_channel(mxc_fbi->ipu, mxc_fbi->ipu_ch);

printk("[5.]\n");

所以我觉得和我打得patch应该是没什么关系吧？不知道您之前是否遇到过类似的问题？

[qiang_li-mpu_se]

请确保display和IPU相关的代码恢复到原始的BSP，再来测试。

或者你有Freescale开发板的话，最好现在开发板上试试在，针对你这个LVDS0的用法，我特地做了一个CONFIG_MX6_CLK_FOR_BOOTUI_TRANS_LVDS_IPU1_DI0的例子，都测试过没问题了。

[尚飞汤 · Accepted solution]

嗨，li，现在的现象看来应该不是我打得patch问题，是否有其他模块干扰到display部分的可能呢？
