How to build fw_printenv and fw_setenv for imx8mq?

[晓锋潘]

我在android 9.0.0_2.0.0以及Yocto L4.14.98_2.2.0环境下编译fw_printenv 和 fw_setenv时一直报错，请问有解决方案吗？log如下：

Hello @wang12zhe ,

Create a new case for your question, please!

And our MPU team will take it, and discuss it with you.

Hi Pan,

   你可以从网上得到很多类似的同行的经验，比如：

https://blog.csdn.net/leochen_career/article/details/81027309 

你之所以编译出错，原因就是makefile中的编译器路径配置不对。

编译这个东西，建议你在linux里编译，先按照linux doc中的一个porting guide 文档描述的standalone模式，把工具链从yocto里导出来。u-boot、kernel代码都整理到一个目录里。当能够用单机模式编译u-boot和内核成功时，单机环境就好用了。

这时候，你再开始编译你的fw_printenv和fw_setenv. 参考上面链接里的经验，编译一下。

或者Yocto里直接编译，我刚刚测试过：

---------------------------

# cd imx-release-bsp

# gedit .build/conf/local.conf

add the line:

IMAGE_INSTALL_append  += " u-boot-fw-utils"   # a space character must be used before "u-boot-fw-utils".

save and exit.

# source setup-environment build

# bitbake u-boot-fw-utils -c compile

# bitbake u-boot-fw-utils -c install

Then succeeded.

-------------------------

Have a nice day!

BR,

Weidong

@weidong_sun 在IMX8QXP上测试，这样操作能 fw_printenv and fw_setenv但 不能用，进入uboot源码编译的却能用，

但怎么自动打包到文件系统能
