NXP(imx8qxp)系列DDR校准以及android镜像烧录

IT利刃出鞘 • 2022-5-21 • app • 阅读 63

NXP(imx8qxp)系列DDR校准以及android镜像烧录,第1张

文章目录 一、源码进行编译二、校准DDR三、修改代码四、阶段测试
记录一次关于nxp平台的imx8qxp系列android11的ddr校准笔记和相关的烧录笔记，因为之前公司没人做过，只有一点一点的去百度相关资料进行尝试。

一、源码进行编译

因为我下载的官方最基础的源码，按照官方文档，进行环境搭建过后，进行 source lunch 后，进行./imx-make.sh,无法编译，这里因为缺少对应的交叉编译工具链。在《Android_User’s_Guide.pdf》的4页里面有对应的说明，可能你们需要你们的组长进行帮助，我这里是之前有imx8系列的环境，我直接打的补丁，具体步骤我没有去研究。
下载对应的镜像文件：
在弄好之前的环境后，进行编译，他告诉我找不到mx8qmb0-ahab-container.img，和mx8qxb0-ahab-container.img，和mx8qxc0-ahab-container.img。这里需要下载对应的工具链，进行脚本编译。
这里可以使用 weget获得，对应的网址如下：

http://www.freescale.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.1.bin

可以直接进行下载
对应的命令如下：

wget http://www.freescale.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.1.bin
chmod +x firmware-imx-8.1.bin && ./firmware-imx-8.1.bin --auto-accept

编译后就会生成3个img
将对应的img防到

/*mx8qmb0-ahab-container.img 放这里*/
MX8QXP/vendor/nxp-opensource/imx-mkimage/iMX8QM
/*mx8qxb0-ahab-container.img，和mx8qxc0-ahab-container.img 放这里*/
MX8QXP/vendor/nxp-opensource/imx-mkimage/iMX8QX

然后在编译，就ok了

二、校准DDR

按照nxp的平台，我们还是按照之前imx8mp系列的步骤，先进行ddr校准工作。对应的工具可以自己去nxp官网下载。或者我这里https://download.csdn.net/download/weixin_51178981/85090517
对应步骤已经在文档里面说的比较清晰了,与mp不同的是他不会生成对应的xx文件。最后进行压力测试，成功的结果如图：

这个时候就需要你保存你的表格。因为里面的东西比较重要，关于你后面代码ddr的校准，相关的文档已经上传 https://download.csdn.net/download/weixin_51178981/85090561

对应步骤如下：需要下载两个工具进行校准,步骤算比较详细了

3、下载scfw工具链：
https://www.nxp.com/design/software/embedded-software/i-mx-software/embedded-linux-for-i-mx-applications-processors:IMXLINUX?tab=In-Depth_Tab

# imx-scfw-porting-kit-1.9.0.tar.gz

4、下载gcc工具链
https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads

# 解压到 /opt 目录下
～～～～～
# tar -zxvf imx-scfw-porting-kit-1.9.0.tar.gz
# cd packages
# chmod a+x imx-scfw-porting-kit-1.9.0.bin
# ./imx-scfw-porting-kit-1.9.0.bin
# cd imx-scfw-porting-kit-1.9.0/src
# tar -zxvf scfw_export_mx8qm_b0.tar.gz 		// for i.MX 8QuadMax MEK
# tar -zxvf scfw_export_mx8qx_b0.tar.gz		// for i.MX 8QuadXPlus MEK
# cd scfw_export_mx8qx_b0
//excel表的倒数第二个文件放入/src/scfw_export_mx8qx_b0/platform/board/mx8qx_mek/dcd/ 并重新命名：imx8qx_dcd_1.2GHz.cfg （表格中的倒数第二个文件）
//最后一个表格中的文件命名为xx.ds用于校准(放入对应的校准工具的script目录下)

/*/MX8QXP/vendor/nxp/fsl-proprietary/uboot-firmware/imx8q/board-imx8qxp.c 官方默认是3GB，这里需要你自己去适配自己的ddr大小，比如我的是4GB，修改如下：

三、修改代码

主要修改部分为uboot阶段的代码,对应的修改如下:

下面的修改比较重要，会影响到你烧写镜像是否成功，我在这里卡了几天，如果这里没有修后，可能会导致你烧录镜像，烧录完uboot后就停止了，不会再往下进行。

还有《Android_User’s_Guide.pdf》的52页的修改也要计的修改，因为i我是4GB所以这里也要修改。

到这里，所有的android的代码已经修改完成，我也成功的启动了开发板。

四、阶段测试

其实阶段测试最重要的就是你flash.bin和uboot阶段命令的测试。
flash.bin测试：
在我们编译完过后，在

/MX8QXP/vendor/nxp-opensource/imx-mkimage/iMX8QX

目录下会有一个flash.bin

/MX8QXP/vendor/nxp-opensource/imx-mkimage/iMX8QX$ ls
bl31.bin                head.hash           mkimage_uboot               scfw_tcm.bin  u-boot-atf.bin   u-boot-spl.bin
boot-spl-container.img  m4_image.bin        mx8qxb0-ahab-container.img  scripts       u-boot.bin       uuu
flash.bin               mkimage_fit_atf.sh  mx8qxc0-ahab-container.img  soc.mak       u-boot-hash.bin

把对应的uuu工具拷贝到这里，或者把flash.bin拷贝到uuu工具目录下，执行下面的命令:

#  ./uuu SDPS: boot -f flash.bin

如果成功的话可以在串口打印上看到下列信息：
