SignalTap -> how to re-define the device chain (auto-detect doesn't work well)?

Hi All, The FPGA devices in the JTAG chain on my board are not auto-detected correctly. In Quartus Programmer, besides an auto-detection of the devices, there is an option to choose the devices ...

    Re-installing the Quartus on the new OS solved the problem, so thank you for your support.

You can't. The chain configuration section of the .stp file is for simple programming of a selected device in the JTAG chain for running the logic analyzer. If you have a more complicated setup, you need to use the Programmer. You can come back to the .stp window after you program the device in the Programmer.

This doesn't help... Even after programming the device with SOF (with STP included) via Programmer, the SignalTap GUI doesn't read the target device correctly. It "sees" the SignalTap signals, but also says that the programmed device doesn't match the SignalTap signals... Usually, this "warning" is solved by programming the device via SignalTap GUI, but in this case, this is impossible since the target device is not detected correctly by the SignalTap GUI and the programming is fail... This is just like some vicious circle... What's the solution?

I'm not sure whether this is important, but there are two devices in the chain - MAX10 (first) and Cyclone 10 (second). The MAX10 is detected correctly, but C10 doesn't ...
