Is it possible to software debug psoc 1 eval device without any ICE. I am using miniprog1 and device is powered through miniprog.
No, you cannot debug a PSoC1 (setting breakpoints, inspecting vars) without an ICE-Cube.
I would suggest you to get hands on a PSoC4 or PSoC5 Prototyping Kit as an affordable entry.
can miniprog3 be used to debug the same device?
Miniprog3 does not work with PSoC1
