GPIO_48 Output Issue on SC200L Module

Dear Quectel Technical Support Team,

I am currently working with the SC200L module and have encountered an issue with the GPIO_48 pin. While other GPIOs such as GPIO_28 and GPIO_54 function as expected, GPIO_48 does not seem to respond correctly when configured as an output.

I have tested using the following commands via ADB shell:

adb shell
su
echo 208 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio208/direction
echo 1 > /sys/class/gpio/gpio208/value

Despite this, the output state of GPIO_48 does not change.

We would appreciate it if you could provide any documentation or support regarding GPIO_48 on the SC200L module. If there are known limitations, required configurations, or hardware dependencies associated with this pin, kindly advise. We also plan to post this issue on your support forum for broader visibility and discussion.

Thank you for your assistance.

This may cause by the GPIO48 is used by other functions.
Or it is initialled with pull down so you cannot operate it by export.
