https://www.nxp.com/docs/en/user-guide/IMX_LINUX_USERS_GUIDE.pdf

在 Fast Boot on i.MX 8M and i.MX 9 Using Falcon Mode and Kernel Optimizations 文档中提到了固件信息，以及下载方法；

# 「Fast Boot on i.MX 8M and i.MX 9 Using Falcon Mode and Kernel Optimizations」网址如下
https://www.nxp.com/docs/en/application-note/AN14093.pdf

2. 硬件信息

开发板：IMX93EVK

电脑系统：ubuntu 20.04，x86_64 架构

3. uboot 构建

在 IMX_LINUX_USERS_GUIDE.pdf 中提到了如下信息：

On i.MX 93, multiple elements are needed:
• imx-boot (built by imx-mkimage), which includes SPL, U-Boot, Arm Trusted Firmware, OP-TEE, Sentinel Firmware, DDR PHY Firmware
• Linux kernel image
• (Optional) Arm Cortex-M33 image
• A device tree file (.dtb) for the board being used
• A root file system (rootfs) for the particular Linux image

imx93 的 uboot 使用 imx-mkimage 来制作；需要如下部分：

SPL：second program loader，二级程序加载器，为 uboot 的一部分，编译 uboot 的时候会一并编译出；
U-Boot：简单理解为内核引导程序，编译 uboot 的时候一并编译出；
ATF：Arm Trusted Firmware，简单理解为由 Arm 提供的项目，支持 Arm 架构上的安全启动和运行时需求；
OP-TEE：Open Portable Trusted Execution Environment，开源的可信执行环境（TEE）框架，先不管；
Sentinel Firmware：应该就是指 EdgeLock Secure Enclave (ELE) firmware；
DDR PHY Firmware：ddr 固件

3.1 交叉编译器下载

方法一：去 arm 网站上下一个

# 我选择的是 arm-gnu-toolchain-13.2.rel1-x86_64-aarch64-none-linux-gnu.tar.xz
# 下载网址见下
https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads

方法二：下载 buildroot，构建一个 sdk

# 下载 buildroot 源码
git clone git://git.buildroot.net/buildroot# 进入 buildroot 目录，配置 imx93 defconfig
cd buildroot
make freescale_imx93evk_defconfig# make menuconfig 去除 kernel 与 uboot 的构建，保存后退出
make menuconfig# 执行构建 sdk 命令
make sdk -j$(nproc --all)# 生成的文件路径如下
ls -alh output/images/aarch64-buildroot-linux-gnu_sdk-buildroot.tar.gz

方法三：使用 Yocto 来构建交叉编译器

# 见另一篇博客
https://blog.csdn.net/liangtao_1996/article/details/137959559

3.2 uboot 编译

# 在 https://www.nxp.com/docs/en/user-guide/IMX_LINUX_USERS_GUIDE.pdf 中提到了下载编译的方法# 下载 uboot 源码，并切换到分支 lf_v2023.04
git clone https://github.com/nxp-imx/uboot-imx -b lf_v2023.04# 进入 uboot 源码，配置 imx93（配置交叉编译器的前提下）
cd uboot
make distclean
make imx93_11x11_evk_defconfig
make -j$(nproc --all)# 编译会生成以下两个需要的文件
ls -alh u-boot.bin
ls -alh ./spl/u-boot-spl.bin# 遇到报错如下：
tools/mkeficapsule.c:21:10: fatal error: gnutls/gnutls.h: No such file or directory21 | #include <gnutls/gnutls.h>| 
# 解决方法：安装如下包
sudo apt-get install libgnutls28-dev

3.2 ATF 编译

# 下载源码，并切换到当前版本 tag：lf-6.6.3-1.0.0；LF 是 linux factory 的缩写；
git clone https://github.com/nxp-imx/imx-atf
cd imx-atf
git checkout lf-6.6.3-1.0.0# 执行 make help 查看编译帮助
make help# 从 make help 中可以知道，执行 make clean 是清除编译；
# 一般的编译命令为 make [PLAT=<platform>] [OPTIONS] [TARGET]
# 所以构建 imx93 的 ATF 命令如下（配置交叉编译器的前提下）
make PLAT=imx93 bl31# 生成的文件如下：
ls -alh build/imx93/release/bl31.bin

3.3 ELE 固件下载

3.6 打包生成 flash.bin

# 在以下文件中，藐视了如何打包 flash.bin
# https://www.nxp.com/docs/en/user-guide/IMX_LINUX_USERS_GUIDE.pdf
4.5.13 How to build imx-boot image by using 
For i.MX 93 A1 and i.MX 91P, to build imx-boot image by using imx-mkimage, perform the following steps:
1. Copy u-boot.bin from u-boot/u-boot.bin and u-boot-spl.bin from uboot/ spl/u-boot-
spl.bin to imx-mkimage/iMX93/.
2. Copy bl31.bin from Arm Trusted firmware (imx-atf) to imx-mkimage/iMX93/.
3. Copy the image of Sentinel firmware container mx93a1-ahab-container.img to imx-mkimage/iMX9/.
4. If using OP-TEE, copy tee.bin to imx-mkimage/iMX93/. The bl31.bin copied in Step 2 must be built
with OP-TEE SPD enabled.
5. Run the following command to generate flash.bin.
• For i.MX 93 A1:
make SOC=iMX9 REV=A1 flash_singleboot

# 拷贝 3.1 编译的 u-boot.bin 和 spl/u-boot-spl.bin 到 imx-mkimage/iMX93/ 目录
cp uboot-imx/u-boot.bin uboot-imx/spl/u-boot-spl.bin imx-mkimage/iMX93/# 拷贝 3.2 编译的 bl31.bin 文件到 imx-mkimage/iMX93/ 目录
cp imx-atf/build/imx93/release/bl31.bin imx-mkimage/iMX93/# 拷贝 3.3 下载的 Sentinel firmware container mx93a1-ahab-container.img 到 imx-mkimage/iMX93/ 目录
cp firmware-ele-imx-0.1.1/mx93a1-ahab-container.img imx-mkimage/iMX93/# 拷贝 3.4 下载的 ddr 固件 lpddr4* 到 imx-mkimage/iMX93/ 目录
# 参考博客：https://xterra2.avnet.com/poc/nxp/buildroot-for-i.mx93
cp firmware-imx-8.23/firmware/ddr/synopsys/lpddr4* imx-mkimage/iMX93/# 进入 imx-mkimage 构建 flash.bin
cd imx-mkimage
make SOC=iMX9 REV=A1 flash_singleboot# 生成的 flash.bin 文件在 iMX93/flash.bin 路径
ls -alh iMX93/flash.bin

4. 将 flash.bin 写入 tf 卡

利用 shell 脚本来快速写入，新建一个命令为 mksdboot.sh 的脚本，给于执行权限；

将 uboot 编译出的文件 flash.bin 和 mksdboot.sh 放入同级目录，执行以下命令就能将 uboot 刻录到 tf 卡；

对于 i.MX 9 seek 为 32k；这个在 IMX_LINUX_USERS_GUIDE.pdf 中有提到；

sudo ./mksdboot.sh

脚本的作用是：

1. 找到 16GB 以下的分区

2. 将 tf 卡的前 1MB 空间写 0

3. 跳过 tf 卡的前 8MB 空间，将剩余空间格式化为 fat

4. 将 flash.bin 文件写入 tf 卡，seek 为 32KB 的地方

虚拟机版本如下：

#!/bin/bash# Determine the absolute path to the executable

后续单独写入命令

# /dev/sdb 是你的 tf 卡被虚拟机识别的节点
sudo dd if=flash.bin of=/dev/sdb bs=32K seek=1 conv=fsync

5. 下载另一版本的 ele

我在调试的时候发现，使用 mx93a1-ahab-container.img，imx93 evk 会无日志输出，使用 mx93a0-ahab-container.img 就行；原因暂不知；

# 在其博客可知，他们用的是 mx93a0-ahab-container.img
# 下载同样的版本
wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-sentinel-0.9.bin# 导出固件，firmware-sentinel-0.9.bin 头部是一段 shell 脚本，赋予执行权限
chmod u+x firmware-sentinel-0.9.bin# 执行 bin 文件，同意许可后会导出固件
./firmware-sentinel-0.9.bin# 导出的文件为： mx93a0-ahab-container.img
ls -alh firmware-sentinel-0.9/mx93a0-ahab-container.img

重新打包生成 flash.bin

# 将 mx93a0-ahab-container.img 拷贝到 imx-mkimage/iMX93/ 目录
cp firmware-sentinel-0.9/mx93a0-ahab-container.img imx-mkimage/iMX93/# 进入 imx-mkimage 构建 flash.bin
cd imx-mkimage
make SOC=iMX9 REV=A0 flash_singleboot# 生成的 flash.bin 文件在 iMX93/flash.bin 路径
ls -alh iMX93/flash.bin

将 flash.bin 再次写入 tf 卡；

6. tf 卡启动日志如下
