jetson agx xaviar刷机过程

一、下载刷机包

https://developer.nvidia.com/embedded/jetson-linux-archive

选择需要的版本，下载这两个包

|---|---|
| Driver Package (BSP) ||
| Sample Root Filesystem ||

二、解压缩刷机包

官方文档：https://docs.nvidia.com/jetson/archives/r34.1/DeveloperGuide/text/IN/QuickStart.html

bash 复制代码

tar xf ${L4T_RELEASE_PACKAGE}
cd Linux_for_Tegra/rootfs/
sudo tar xpf ../../${SAMPLE_FS_PACKAGE}
cd ..
sudo ./apply_binaries.sh

这里 ${L4T_RELEASE_PACKAGE}是BSP包的路径，$ {SAMPLE_FS_PACKAGE}是sample root filesystem路径。

三、刷机

将Jetson用usb口连接在电脑上，按抓recover按钮的同时，重启Jetson，这样Jetson就会进入Recover模式。

执行：

bash 复制代码

sudo ./flash.sh ${BOARD} mmcblk0p1

这里${BOARD}选项：

Module	Module type *	Carrier board	Configuration	Configuration notes
Jetson AGX Orin 32 GB (P3701-0000)	Development	Jetson AGX Orin reference carrier board (P3737-0000)	`jetson-agx-orin-devkit`	Flashes QSPI-NOR and eMMC
Jetson Xavier NX (P3668-0000)	Development	Jetson Xavier NX reference carrier board (P3509-0000)	`jetson-xavier-nx-devkit`	Flashes QSPI-NOR and microSD Card
Jetson Xavier NX 8 GB-DRAM (P3668-0001) & 16 GB-DRAM (P3668-0003)	Production	Jetson Xavier NX reference carrier board (P3509-0000)	`jetson-xavier-nx-devkit-emmc`	Flashes QSPI-NOR and eMMC
Jetson AGX Xavier 16 GB-DRAM (P2888-0001), 32 GB-DRAM (P2888-0003), & 64 GB-DRAM (P2888-0005)	Development & production	Jetson AGX Xavier reference carrier board (P2822-0000)	`jetson-agx-xavier-devkit`	Flashes internal eMMC
Jetson AGX Xavier Industrial (P2888-0008)	Production	Jetson AGX Xavier reference carrier board (P2822-0000)	`jetson-agx-xavier-industrial`	Flashes eMMC
	----	--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------		*

注意：在刷机过程中可能会遇到 bootloader/tergrasign_v3.py的相关报错，原因是刷机包中的python脚本是用python2写的，我们电脑上可能用的是python3。修改bootloader/tergrasign_v3_util.py文件如下（注释掉原来的write_file函数）：

python 复制代码

'''             
Write data to given file handle
'''
#def write_file(file_handle, data):
#    try:
#        if isinstance(data, str):
#            file_handle.write(data.encode('utf-8'))
#        else:
#            file_handle.write(data)
#    except IOError:
#        info_print("Cannot write %s \n" %(file_name))
                
def write_file(file_handle, data):
    # Handle different data types
    if isinstance(data, bytearray):
        # Bytearray - convert to bytes or string as needed
        if hasattr(file_handle, 'mode') and 'b' in file_handle.mode:
            file_handle.write(bytes(data))
        else:
            file_handle.write(data.decode('utf-8', errors='ignore'))
    elif isinstance(data, bytes):
        # Bytes object
        if hasattr(file_handle, 'mode') and 'b' in file_handle.mode:
            file_handle.write(data)
        else:
            file_handle.write(data.decode('utf-8', errors='ignore'))
    elif isinstance(data, str):
        # String object
        if hasattr(file_handle, 'mode') and 'b' in file_handle.mode:
            file_handle.write(data.encode('utf-8'))
        else:
            file_handle.write(data)
    else:
        # Try to convert to string as fallback
        file_handle.write(str(data))

再执行

bash 复制代码

sudo ./flash.sh ${BOARD} mmcblk0p1

等待烧录结束，重启，刷机完成。

四、安装软件
