Dear All,
I am developing an application where I need to get the nRF5340 to the low power state, where the chip is consuming less than 10uA when it idle, while using the nRF7002 companion chip.
Starting with the simple blinky example, adding to the prj.conf
CONFIG_LOG=n CONFIG_SERIAL=n
I am able to get the device to work with about 10uA on average.
The next step is to have a more complex project configuration that looks like this:

When I am setting the CONFIG_SERIAL=n, I am getting the following error:

687 | initstruct->pins.io1_pin = QSPI_IF_BUS_IO1_PIN;Uncommenting the CONFIG_PINCTRL=y line at the end of my prj.conf allows for the project to build, but the current consumption while sleeping is quite high (~350uA):
My main looks like this:
int main(void)
{
while (1) {
k_sleep(K_FOREVER);
}
}
I have tried the following Kconfigs as well, but without any changes:
CONFIG_TFM_LOG_LEVEL_SILENCE=y CONFIG_NRF_WIFI_LOW_POWER=y CONFIG_NRF70_QSPI_LOW_POWER=y
I have also tried allowing for serial in the prj.conf and powering it down in the code, setting the corresponding Kconfigs, but that also did not work.
I have also seen this article https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/optimizing-power-on-nrf53-designs
and tried to add the prj.conf in the sysbuild/ipc_radio described in step 1. This also did not made any difference.
I think that the issue that I am seeing is that the project is being built with the CONFIG_PINCTRL.
I am using nRF connect SDK v3.1.1.
Any ideas?
Thank you very much.
