The development board is automatically mounted after inserting the SD/TF card.

Test platform-hisi-dv500

To implement automatic mounting on a Linux system after a TF card (Micro SD card) is inserted, similar to the fact that the insertion of an SD card/TF card will also trigger kernel events. You can use the udev tool to monitor and process these events and create a udev rule file. To capture the TF card insertion event.

1: Create a udev rules file, such as /etc/udev/rules.d/100-tfcard.rules, and add rules

2:添加SUBSYSTEM=="block", ACTION=="add", KERNEL=="mmcblk*", RUN+="/opt/sdcard.sh"

Where mmcblk* is your tfcard, /opt/sdcard.sh is your mounting script

3: Create a mount script

#!/bin/sh

# device node

DEVICE="/dev/mmcblk1"   #sd card

MOUNT_POINT="/opt/sd"  # mount dir

# check if mount dir exit if not create it

if [ ! -d "$MOUNT_POINT" ]; then

    mkdir -p "$MOUNT_POINT"

fi

# mount

mount "$DEVICE" "$MOUNT_POINT"

 

4: Make rules take effect udevadm control --reload-rules

5: Give the script permission chmod a+x sdcard.sh

Test: automatic mounting successful
