[attach]4456[/attach]本文适用OpenHarmony系统，本次使用的是触觉智能EVB3568开发板，搭载瑞芯微RK3568芯片

<b>一、查看文件路径</b>

首先init.rkxxx.cfg文件在系统路径/vendor/etc/，如下图所示：

C:\Users\industio>hdc shell# cd vendor/etc/# lsaudio fstab.rk3568 iqfil.json soc_perfbattery hdfconfig iqfiles thermal_configcgroup_sched init onsdistributedhardware init.rk3568.cfg paramfirmware init.rk3568.usb.cfg ressched"

二、文件传至本地

将需要需要修改的cfg文件从文件系统中拉下来放在本地目录，命令是：hdc file recv '系统路径' '本地文件路径'，如下图所示：

C:\Users\industio>hdc file recv /vendor/etc/init.rk3568.cfg D:\[I][2024-07-25 10:49:35] HdcFile::TransferSummary successFileTransfer finish, Size:3581, File count = 1, time:127ms rate:28.20kB/s
三、修改文件

在cfg文件中增加权限，注意在对文件修改不要使用TAB键，复制前一行代码后再修改防止出错

{ "import" : [ "init.${ohos.boot.hardware}.usb.cfg" ], "jobs" : [{ "name" : "pre-init", "cmds" : [ "write /proc/sys/vm/min_free_kbytes 10240", "mount debugfs /sys/kernel/debug /sys/kernel/debug mode=755", "write /sys/kernel/debug/hisi_inno_phy/role peripheral" ] }, { "name" : "init", "cmds" : [ "write /proc/1/oom_score_adj -1000", "chown system system /sys/kernel/hungtask/userlist", "symlink /dev/block/platform/fe310000.sdhci/by-name /dev/block/by-name" ] }, { "name" : "boot", //在此位置添加设备权限 "cmds" : [ "write /sys/block/zram0/disksize 1024M", "mkswap /dev/block/zram0", "swapon /dev/block/zram0", "chmod 777 /dev/ttyAMA2",+ "chmod 666 /dev/bus/usb/005/001"+ "chmod 666 /dev/bus/usb/005/002" "chmod 775 /sys/class/rfkill/rfkill0/state", ] }, { "name" : "post-fs-data", "cmds" : [ "restorecon", "restorecon /data/updater" ] } ], "services" : [{ "name" : "ispserver", "path" : ["/vendor/bin/ispserver"], "once" : 1, "secon" : "u:r:ispserver:s0", "uid": "ispserver", "gid": [ "ispserver", "camera_host" ] } ]}
四、文件推送

当修改完成后将文件推送回去，命令如下：

hdc shell mount -o remount,rw /vendor //重新挂载设备，将设备改为可读可写hdc file send “本地路径” “/vendor/etc/init.rkxxx.cfg” //将修改好的文件覆盖到系统当中hdc shell reboot //将文件推送回去，系统重启
