I am trying to change the pinmux config in CBoot using this code: NV_WRITE32(NV_ADDRESS_MAP_PADCTL_A0_BASE + 0xd040, 0x00000005); // Z3 NV_WRITE32(NV_ADDRESS_MAP_PADCTL_A0_BASE + 0xd058, 0x00000005); // Z5 NV_WRITE32(NV_ADDRESS_MAP_PADCTL_A0_BASE + 0xd010, 0x00000009); // Z6 NV_WRITE32(NV_ADDRE…

hello avv, please use the 32-bit register write marco in the NV_WRITE32(), you may also read it back and print it out to ensure you’ve gotten the correct register. you’re not seeing it changes, perhaps you’re doing this before GPIO/pinmux initialization from the core DTSI files.
