Hi Andy,

I am getting 0.500 V during startup , I am not sure what is causing this issue. I can share the entire schematic in private ticket for review

Hi.

Are you able to confirm if this is a software or hardware issue please?

If you powerup the board using VSET to set the voltage (SoC erased or held in reset), do you see 3.3V on the output?

Thanks
Andy
