Regarding current consumption for the WiFi shell application.

Hi, I am facing an issue while running the WiFi Shell application on nrf7002dk. I am using nordic power profiler kit 2 for measuring the current using P22. On connecting the power profiler as mentioned Getting started page, I am getting 0 uA in the nrfConnect desktop application. The screenshot is attached below: On connecting the other way round, I am getting current as 1.44 uA. The screenshot is attached below: Can anyone help in figuring out what is wrong? Also, what is the ideal expected current for WiFi shell example with power save on? Thanks in advance.

Issues flashing the NRF52480 custom board with the NRF52480 DK board.

Hello, We are currently facing a challenge with flashing our custom board with the chip NRF52480. We are using the NRF52480 DK board as our programmer. We compiled the code via VS code and tried flashing compiled HEX file using the programmer tool but it always returns an error. When we flash same hex file on the DK board everything works fine. But will throw errors when flashed on the custom board using the DK as its programmer. We are using the exposed SWDIO pinouts on our custom board. Please how do we address the issue? Here's the Error messages when trying to flash the custom board. Error: Failed with exit code 1. Failed to device info one or more devices: * 1050283227: [jlink] JLINKARM_DLL_ERROR, code: Nrfjlink. Message: Operation device-info failed, [jlink] JLINKARM_DLL_ERROR. 12:06:40.764 Using nrfutil device to communicate with target via JLink 12:06:42.994 Reading readback protection status for Application
