Honored ContributorQuery FPGA device ID from Linux
We have a board that accepts both an Cyclone V SX or ST part, and also one with more or less logic. Given device availability varies considerably, we have some boards built with one part and some wi...

Honored ContributorIf the device (SX vs ST) have the same logic density, then their IDCODE will be the same:
https://documentation.altera.com/#/00005773-AA$NT00080225 Now if the density is different, when you use FPGA manager to program the FPGA image, you can code in such a way that the FPGA manager returns error to the program if the attempt to program the FPGA is unsuccessful (which is the case when you program a part with mismatch image). Presumably then you can load the second image which is correct for the aforementioned device. I know this is not pretty... but could be something :)
