Gpio6 of wp7608 on mangOH


Hi All,

I would like to understand the GPIO6 functional behaviour. Does this gpio has any specific functionality wrt to modem ?

Initially, this signal was configured as input and no access from linux as shown below. It means any specific reason for configuring as input ?

+WIOCFG: 2,16,0,0,1,0,0
+WIOCFG: 6,0,0,0,1,0,0
+WIOCFG: 7,16,0,0,1,0,0
+WIOCFG: 8,16,0,0,1,0,0
+WIOCFG: 13,16,0,0,1,0,0
+WIOCFG: 21,16,0,0,1,0,0
+WIOCFG: 22,16,0,0,1,0,0
+WIOCFG: 23,16,0,0,1,0,0
+WIOCFG: 24,16,0,0,1,0,0
+WIOCFG: 25,16,0,0,1,0,0
+WIOCFG: 28,16,0,0,1,0,0
+WIOCFG: 29,16,0,0,1,0,0
+WIOCFG: 30,16,0,0,1,0,0
+WIOCFG: 31,16,0,0,1,0,0
+WIOCFG: 32,16,0,0,1,0,0
+WIOCFG: 33,16,0,0,1,0,0
+WIOCFG: 35,16,0,0,1,0,0
+WIOCFG: 42,16,0,0,1,0,0


So I changed this signal to output from the AT Commands as shown below


I would like to use the gpio6 as like gpio2(Reset signal to Ethernet bridge ) in mangoH.
Is that possible to achieve the same behavior with the gpio6 ?



Hi Siva,

To my understanding, GPIO6 of WP7608 is named RESET_OUT_N and serving as reset signal for external peripheral.
Please refer to PTS section 4.14 “Reset Out (RESET_OUT_N)” for details.

If that doesn’t match your requirement, +WIOCFG can be used to configure and allocate it to Linux sysfs/Legato use.
That is possible since Release 6, please refer to table in section 14.2 of customer release note for that change:,-d-,1-customer-release-notes/

Note, the original “+WIOCFG: 6,0,0,0,1,0,0” means it is allocated as RESET_OUT_N by default for MangOH.

Hope it helps.


Hi Stirulaka

The GPIO6 is special IO of module.
It has multi function in different condition.

If some “custom” function is enable, it will be occupied. for example “DSSS”- Dual SIM Switch System, RESET_OUT_N.

Please avoid such multi function pin.
