thats absolutely right i am just looking for a way to switch the slot on manual reset instead of its automatically trigerring the reset

Yes. To start the app after OTA, it needs to reset.

are you sure?

coz earlier when using the ota on the same board it used to swap only during manual reset instead of automatically trigerring a reset thats what i want right now

[quote user="manav555"]I just want to swap the partition only when device is turned off and than turned on[/quote]

This will trigger a reboot and a complete reset of the device, no way around this.

I just want to swap the partition only when device is turned off and than turned on

means not reset and swap automaticlly as soon as ota is pushed instead wait for the device to be reseted by the user mannually than swap the partition please tell me how to do that

[quote user="manav555"]hence kindly tell me a way so that either i can set the gpio high even during partition switching or can switch the partition during the device reboot that is when device turned off mannually by the user [/quote]

There's no way to change this behaviour. When the device is reset, all GPIOs will be set to the default state, disabled, and not change untill after the power on reset is finished. You will need an external pull up resistor here, no way around that.

yes you got it right gpio is enabling the power supply

but the problem is that we cant change anything in the hardware since its already up for production

hence kindly tell me a way so that either i can set the gpio high even during partition switching or can switch the partition during the device reboot that is when device turned off mannually by the user

I assume the GPIO is enabling the power supply so that when the GPIO is not longer in a high state, the power supply will switch off? In that case, you need an external pullup resistor on the GPIO. When the device is reset, all GPIOs will be disconnected so you need something external to set the logic level.
