Honored ContributorThank you for your answer, MSchmitt.
--- Quote Start --- check the labeling on your device with the datesheet if you have the correct device mounted. --- Quote End --- It is the correct device. The label on the device package says "EPM570T100C4N". This is equal to the device setting in the corresponding Quartus project. --- Quote Start --- if you use a new unprogrammed device will it be destroyed as well ? --- Quote End --- No, it is not destroyed, but even when it is programmed, it may work as expected. There are both cases (destroyed and not destroyed) when programmed, and there may be both cases when not programmed - but I can't verify that. --- Quote Start --- check wheter you have two outputs connected. --- Quote End --- No outputs are connected with each other. --- Quote Start --- Recheck all max 2 pins the device on the pcb as it is realy connected with the datasheet --- Quote End --- Well, the datasheet (device handbook) does not contain the pinout, does it? Would you recommend to take the ".pin" file of my Quartus project and to compare it with the PCB schematics?
