Not floating: GPIO0_A3 (USR1_SWITCH#) has an external 4.75k pull-up (R9) to 1V8_S3 on the SoC side of D11, sheet 29 of https://wiki.kobol.io/helios64/files/schematics/Helios64_Schematics_Rev1.2.pdf Armbian ships the same pinctrl; with no User1 button attached the IRQ count stays 0 after 29 minutes of uptime.
