20250519使用TF卡將NanoPi NEO core開發板刷機為Ubuntu core22.04.3系統完成之后執行poweroff自動關機

1、h3-sd-friendlycore-xenial-4.14-armhf-20210618.img.gz 在WIN10下使用7-ZIP解壓縮/ubuntu20.04下使用tar
2、Win32DiskImager.exe 寫如32GB的TF卡。【以管理員身份運行】
3、TF卡如果已經做過會有3個磁盤分區，可以使用SD Card Formatter/SDCardFormatterv5_WinEN.zip格式化TF卡。DiskGenius可以嘗試。

制作好Ubuntu core22.04.3系統的IMG固件之后，還需要你編輯TF卡中的文件：
1、修改H:\eflasher.conf
autoStart=/mnt/sdcard/friendlycore-jammy
autoExit=true

2、root@NanoPi-NEO-Core:/opt# vi run-eflasher.sh?
root@NanoPi-NEO-Core:/opt# cat run-eflasher.sh?
poweroff

如果能夠直接編輯IMG固件就好了。到時候寫TF卡之后不需要每次都來編輯這兩個文件。

緣起：在上電之后，TF卡將NanoPi NEO core開發板刷機之后自動關機，安全/保險一點。
【不會丟數據^_】

【你放心吧】生產線的工人只會問你插入TF卡之后上電幾分鐘刷機完成。【2分鐘搞定】
不要想他們會去看DEBUG串口打印信息。

【切記，不需要在H:\eflasher.conf的autoStart項目之后手工輸入autoExit項目。conf配置文件有/自帶的。^_】
1、使用Win32DiskImager.exe寫TF卡之后，將TF卡插入讀卡器之后插入到WIN10/WIN11的電腦。
【理論上在ubuntu20.04.6下使用gedit修改也OK的。】
修改H:\eflasher.conf。【具體盤符H以您的電腦為準。^_不通的電腦肯定會變化的！】

C:\TF1emmc-jammy22.04\FriendlyARM\eflasher.conf

; This is the eFlasher configuration file.
; See http://wiki.friendlyarm.com/wiki/index.php/EFlasher for detailed information.

[General]
; Automate OS installation at system startup,
; Use the "autoStart" field to specify the image path or RAW image file,
; The RAW image file can be a gzip compressed file,
; The RAW image file extension must be ".raw" or ".gz",
; Available values: friendlycore-jammy
autoStart=friendlycore-jammy

; If the "autoExit" field set to true, the eflasher-gui will automatically exit after burning or restoring is completed,?
; You can do something else after burning or restoring by modifying /opt/run-eflasher.sh.
autoExit=false

; Don't erase the flash before burning, useful if you only want to update part of the system files
disableLowFormatting=false

[UI]
; HDMI overscan option, examples:
;?? ? screenSizePercent=auto
;?? ? screenSizePercent=90
screenSizePercent=auto

welcomeMessage=
hideMenuButton=false
hideBackupAndRestoreButton=false
hideStatusBar=false
autoRebootWhenSDBeEjected=true

修改成為：

2、將TF卡插入到NanoPi NEO core開發板，使用vi編輯run-eflasher.sh：【加入poweroff關機】
