Welcome in the forum!
"I've used PSoC Programmer to check the firmware level on my MiniProg" Did you only check or did you indeed update the miniprog3 firmware? Actual version for PSoC programmer is 3.26
"Instead of my PSoC 5 I..." Your selected device in Creator is hopefully a PSoC 5LP chip? Same on your pcb??
When using the programmer, do the green "Device powered" show up on the screen?
Thanks Bob, it's a blown Miniprog. :(
Too bad! How did you manage that?
