请教求助： rk3288 + rk818 无法正常启动

yubang · 发表于 2016-11-2 17:25:29

各位好！

用RK3288 做了一个板子， PMIC用的是 RK818；
用的系统是android5.1的，内核中的dst文件开始时是没有添加rk818的相关的；我参考其它的dts文件，添加了对rk818的支持；

这样改动后，把各个映像烧写进去，uboot启动能够识别到rk818，内核启动也能识别到rk818；
但是遇到了问题，就是系统只能进入到recovery模式，每次重启后，uboot引导内核，然后内核也是调到recovery模式下，无法正常进入系统。

以下是启动时uboot的打印：

然后后面启动到recovery模式的命令行。

1）我把这些我改动后，编译出来的所有映像，下载到firefly3288 reload 板子， reload板子能够正常启动到android系统中；并不会像我的板子那样一直进入recovery模式；

2）我查看了内核的代码，它是会读取cpu的pmu相关的寄存器来决定是进入recovery模式，还是 normal模式的，我想咨询下，哪些方面会影响这些寄存器的值呢？  是不是我rk818配置的哪组电压不对吗？

3）一直进入recovery模式，我做了排除，应该是和我板子的recovery按键没关的，在uboot启动时，如果不按recovery按键，它是不会进入升级状态的；

4）有哪个朋友，也是用rk3288 + rk818 做板子的吗？若有，能否给一下建议，是不是我的哪里的改动不对？

谢谢！

got recovery cmd from misc.

这个是否没有清空 misc 分区所致？

怎么清空 misc分区呢？我有把misc.img也烧写进去；

busybee · 发表于 2016-11-3 09:50:03

dd if=/dev/zero of=misc_zero.img bs=16k count=3
然后把这个 misc_zero.img 烧写到 misc 分区即可。具体见

我根据你的建议，改动了misc映像升级进去；
板子现在不会进入recovery模式下了；但是启动后，死掉了，停在以下的地方：（每次重启，基本是停在同样的地方）

1、同样在firefly3288 reload中用了一样的固件，reload的正常；

2、请教，能从这个启动的打印判断问题出在哪里吗？谢谢；

busybee · 发表于 2016-11-4 09:24:52

从内核日志上确实看不出哪里出问题了。仔细比对一下硬件吧。

在內核中打印並略過 disable動作

看看這樣去加印一些訊息, 對你有沒有幫助

是的,
因為目前遇到了開機不穩定的現象, 有先將 dvfs ddr 的部分在 dts檔案中先做 disable的動作,

也有試著根據下方連結嘗試做修改驗證
http://www.voidcn.com/blog/huangkaiyue1/article/p-6112359.html
仍然無解,

目前 ddr Freq 固定跑在 300M,
持續驗證釐清中...

是的,
因為目前遇到了開機不穩定的現象, 有先將 dvfs ddr 的部分在 dts檔案中先做 disable的動作,

我看到有3128的dts文件，关于rk818部分，有以下的设置：
&rk818 {
gpios =<&gpio1 GPIO_B1 GPIO_ACTIVE_HIGH>,<&gpio1 GPIO_A1 GPIO_ACTIVE_LOW>;
cpu_det_gpio = <&gpio0 GPIO_D0 GPIO_ACTIVE_HIGH>;
power_hold_gpio = <&gpio0 GPIO_D6 GPIO_ACTIVE_HIGH>;
rk818,system-power-controller;
rk818,support_dc_chg = <1>;/*1: dc chg; 0:usb chg*/

而我现在用的，只是：
&rk818 {
gpios =<&gpio1 GPIO_B1 GPIO_ACTIVE_HIGH>,<&gpio1 GPIO_A1 GPIO_ACTIVE_LOW>;
rk818,system-power-controller;
rk818,support_dc_chg = <1>;/*1: dc chg; 0:usb chg*/

没有这两句：

cpu_det_gpio = <&gpio0 GPIO_D0 GPIO_ACTIVE_HIGH>;
power_hold_gpio = <&gpio0 GPIO_D6 GPIO_ACTIVE_HIGH>;

这个有什么影响吗？

我看到我的电路没有这两路管脚接过去；
