定制Uboot报Can't find PMIC:PFUZE100

leavs · ‎04-19-2016

参考 fsl-yocto-imx-4.1.15_1.0.0 BSP文档定制Uboot，移植完成之后，在串口中出现如下错误：

开发板是我们自己设计的，不确定为什么会报这个错误，有什么解决方法吗？

我已经解决，加QQ 281362556 或者wechat ：aiwesky2009

jiepeng · ‎07-28-2016

我也遇到同样的问题，只是我已经处理了，遇到新的问题

希望能加qq：281362556 或者wetchat：aiwesky 交流

I got the same problem

You can modify the u-boot/include/configs/mx6_common.h to avoid ldo bypass check, which can fit the discrete power supply.

48 #define CONFIG_LDO_BYPASS_CHECK

49 #undef CONFIG_LDO_BYPASS_CHECK

void_ · ‎05-18-2016

非常谢谢你的回答，但是如何屏蔽Can't find PMIC:PFUZE100 这个问题我已经知道如何处理了，我强调的问题是如何通过源码编译生成MFG中使用的uboot固件

你好：

我们公司的板子根据imx6q_sabresd裁剪的，烧写遇到和你相同的问题，请问Can't find PMIC:PFUZE100 这个问题你是怎样解决的？

BiyongSUN · ‎05-22-2016

In the BSP 3.10 and later, the uboot is shared with mfg tool.

ispsubb · ‎05-04-2016

感谢biyong.sun 的帮助。前面的提到的点都是正确的。

昨天下午得到你们的FAE帮助，问题解决了，这里我mark一下。

关于这一点：

2. CONFIG_LDO_BYPASS_CHECK is the definition in uboot-imx\include\configs\mx6_common.h

If you undefine it, will never see the No PMIC found!

这一点我有去注释掉，但我编译的时候编译不过，bitbake -c compile u-boot-imx-mfgtool

但我在uboot 中注释掉了对pmic 初始化的函数，这样没有卡住在uboot。

另外我们的板，还有一个原因是采用的mini USB ，然后用了一根转接线，而问题就在这根转接线上，这个OTG转来接U盘的。

在L3.0.35是可以的，但在L3.14.52上是不行的。这一点是得到你们同事的确认。最开始有怀疑这根线，就是因为L3.0.35可以烧，就pass掉这一点了。L3.14.52做得更加规范了。

void_ · ‎05-17-2016

你好，我现在也出现了和你一样的情况，用MFG工具烧录5.1的镜像时出现Can't find PMIC:PFUZE100 ，原因就和你的一样没有PMIC，所以能否告知你是如何制作新的MFG工具中uboot固件呢？

ispsubb · ‎05-18-2016

Can't find PMIC:PFUZE100 屏蔽掉相应的代码，就可以了。

加你QQ告诉你

ygzhou · ‎07-28-2016

Hi li chao:

我也遇到同样的问题，Can't find PMIC:PFUZE100，怎么蔽掉相应的代码，能否也告知一下，谢谢

你好，我们公司的板子是基于sabresd改的，也出现类似问题，打印信息如下：

请问你说的:Can't find PMIC:PFUZE100 屏蔽掉相应的代码，就可以了

相应代码的是哪些呢？我的QQ597367138，能告知你的QQ吗？

谢谢！

1. Have you modified the device tree for your customer board?

现在是烧写不了，尝试修改过mfgtool uboot ，linux 固件。你指的device tree应该如何修改？我尝试去掉pmic ，但与其他相关性较大。并且在mfgtool uboot中置空了对pmic 初始化的函数，这样才可以不至于卡在Can't find PMIC:PFUZE100

2. Have you finished the DDR calibration and apply the result to the uboot as porting guide mentioned?

DDR 较准与压力测试有做，并且回填到了mfgtool firmware 。用的1.03 版本的工具做的测试。

3. Have you got the entire log from the power on to check?

我们有 fsl demo 板，我将demo烧写成功与我们的板烧写不成功的log有做对比，没有从中发现什么问题。

另外：我有尝试mfgtool2-yocto-mx-sabresd-emmc-1.2g.vbs , 就是LDO打开的，现象log一样。

您的邮箱是多少呢？能不能直接给你发邮件？这个问题卡了很久，然后你的回复虽然很及时，但我要过很久才能查看得到。

BiyongSUN · ‎05-04-2016

1. Please use the L4.1.15_1.0.0_ga-mfg-tools to try for your L4.1.15_1.0.0.

Please try this first.

2. CONFIG_LDO_BYPASS_CHECK is the definition in uboot-imx\include\configs\mx6_common.h

If you undefine it, will never see the No PMIC found!

3. How about the VBUS hardware design, it is swiched by usb id or fixed the supply by board?

Because it is blocking at the polulate disk, it could be that reason the VBUS is conflicted with VBUS on PC, which is not isolated the VBUS phyiscally.

You can try to change to another computer to check. and also you can check with the window device manage to see if you have the Updater .

你好，我用L3.14.52_1.1.0_ga-mfg-tools.tar 中自带的 mfgtool2-yocto-mx-sabresd-emmc-1.2g.vbs 打开去烧写，这个脚本打开看过了，里面内容如下：

Set wshShell = CreateObject("WScript.shell")

wshShell.run "mfgtool2.exe -c ""linux"" -l ""eMMC"" -s ""board=sabresd"" -s ""mmc=3"" -s ""ldo=-ldo"" -s ""sxdtb=sdb"" "

Set wshShell = Nothing

烧写的现象是一样的，还是烧不进去。

jump to the os image 后卡在 no device detect 的地方。

Hi leavs

suggest to check signals by oscilloscope and check values of

i2c pull-up resistors. For custom board bringup it may be useful

to follow Chapter 1 Porting U-Boot attached Porting Guide.

Best regards

igor
