Hi. First time posting. I have a Microchip Studio project that works reliably at 5V with an ATTiny 441. However, a recent HW change requires operation at 3.3V and I have not been able to get this configuration to work. At any voltage under 4.5V I am unable to read fuses, read the device signature or program or debug the device.
The MPLab IDE appears to have voltage level options but I can't find the equivalent in Microchip studio:
Does this option exist and if so, where?
