ID:212006 Some devices in current device list cannot be added to selected programming mode <name>. Do you want to clear all devices in current device list and switch to selected mode?

CAUSE: You directed the programmer to use the specified programming mode for the current Chain Description File (.cdf), but the mode does not support the devices you added to the CDF. The Quartus Prime software is asking whether you want to switch to the specified programming mode, which will clear all the devices from the CDF.

ACTION: Click Yes to clear the devices from the current CDF and switch to the selected mode, or click No to cancel the operation.
