Hi everyone.
Really odd question - we've tried to setup GPIO1_A4 as an input pin on our Core1106 boards, but checking it with sysfs operations always shows it as HIGH (1). We've set it as an input in sysfs. We've checked and it doesn't multiplex to anything. We're using the Pico Pi W image with our expanded changes and we're trying to setup the GPIO1_A4 as input but we're having issues. Other pins like GPIO2_A7 work but we need the GPIO1_A4.

Hello, the GPIO1_A4 of the Core1106 with Wi-Fi module is connected to the internal Wi-Fi module and is not exposed. Only the Core1106 without Wi-Fi module has it exposed.
If you are using the Core1106 without Wi-Fi module, please check if the Bluetooth-related part of the device tree is using it.

Hey, thank you for this.
We're using the Core1106 with Wifi so this is likely the issue. We did go and re-check your documentation and it's not marked as disconnected in the pinout excel . We do see it's connected now in the schematic but this should probably really be marked correctly in the pinout as well.

I'm sorry, it seems that there was an error in the document organization. The correct information should be: GPIO1_A3 and GPIO1_A4 are not connected, while GPIO1_A2 is connected. I informed the relevant colleagues to make the corrections.
