一、从window下发送文件到板端

挂载SD卡:

mount /dev/mmcblk0p1 /mnt/tfcard

启动板端服务器:

udpsvd -vE 0.0.0.0 69 tftpd -c &

windows中启动TFTP客户端

单个文件发送:

window中tftp命令：

从当前本机，向远端192.168.1.27 中发送C:\Users\Administrator\Downloads\test.wav 文件

TFTP.EXE -i 192.168.1.27 PUT C:\Users\Administrator\Downloads\test.wav

使用bat脚本多文件发送：(注意检查更换目标IP地址、本地路径、目标路径)

@echo off
setlocal

:: Set the IP address of the TFTP server
set TFTP_SERVER=192.168.1.27

:: Set the source directory path (modify as per your actual situation)
set SOURCE_DIR=Y:\AX620Q\kanhujia_AX620E_SDK_V3.0.0_20241120230136_NO1951\build\out\AX620Q_nor_arm32_k419\images\sd_update_pack

:: Set the destination directory path (modify as per your actual situation)
set DEST_DIR=/mnt/tfcard/bin

:: Set the list of files to be transferred (relative to SOURCE_DIR)
set FILES=customer.img ddrinit.img dtb.img dtb_b.img kernel.img kernel_b.img logo.img logo_b.img opt.img rootfs.img spl.bin uboot.bin uboot_b.bin version_info.txt

:: Switch to the source directory
cd /d %SOURCE_DIR%

for %%F in (%FILES%) do (
    echo Uploading %SOURCE_DIR%\%%F to %DEST_DIR%/%%F...
    
    :: Note: Not all TFTP clients support specifying a remote file path directly.
    :: If your TFTP client and server both support it, you can use the following command:
    tftp -i %TFTP_SERVER% PUT %%F %DEST_DIR%/%%F
    
    :: If not supported, remove the line above and uncomment the line below:
    REM tftp -i %TFTP_SERVER% PUT %%F
    
    if errorlevel 1 (
        echo Failed to upload %%F.
	echo Press Enter to exit...
	pause >nul
        exit
    )
)

echo All files uploaded successfully.

:: Wait for the user to press Enter before closing the console window
echo Press Enter to exit...
pause >nul

endlocal

效果如下：

二、从板端获取目标服务端的文件：

需要先启动服务端的服务器， (Windows下tftp服务器配置都差不多) ，以SecureCRT为例子：

打开全局选项：

指定TFTP服务器的上传/下载目录

启动tftp服务器

单个文件获取：

Linux中tftp命令：

从192.168.1.4 远端中的C:\Users\Administrator\Downloads中获取stream_chn0_Apr–5-03-44-47-1970.h264 文件

板端使用shell脚本，循环获取多个远端(对应上方下载目录)文件到板端(注意更换ip地址和文件名)

TFTP_SERVER="192.168.1.4"
FILES="customer.img  ddrinit.img dtb.img dtb_b.img kernel.img kernel_b.img logo.img logo_b.img opt.img rootfs.img spl.bin uboot.bin uboot_b.bin version_info.txt"  

for FILE in $FILES; do
    echo "Uploading $FILE..."
    tftp -g -r "$FILE" "$TFTP_SERVER"
    if [ $? -ne 0 ]; then
        echo "Failed to upload $FILE."
        exit 1
    fi
done
echo "All files uploaded successfully."

效果如下：
