I have the following error while executing the command ise-prog-prom to synthesize the vhdl on the platform :
error:impact:2070 There are only 0 devices on the chain. Position 1 does not exists.
I have tried to look online for some answers but I've had no luck so far.
Does anyone know where this bug come from and, even better, how to fix it ?
Here is the log I have :

ERROR:iMPACT:2070 - There are only 0 devices on the chain. Position 1 does not
exist.
make: *** [ise-prog-prom] Error 1
This message is generated because your programmer cannot find any JTAG devices on the chain to program. It's not connected to the device you're trying to program.
How to troubleshoot that specifically is hard to say, I would suggest for starters that you make sure the programmer is connected correctly to the board. If you're using the JTAG Platform Cable II like I do, this means the indicator LED on the programmer will be lit up green (not yellow). Then I would refresh the JTAG chain. If the solution isn't immediately obvious, see if this page is helpful to you at all.
