Error 209015 programming in Quartus 15-1-2 (but not in 15-0-0)

Hi,

I am getting an error when programming my Arria10 (Reflex Alaric board):

Error (209015): Can't configure device. Expected JTAG ID code 0x02E050DD for device 1, but found JTAG ID code 0x00000000. Make sure the location of the target device on the circuit board matches the device's location in the device chain in the Chain Description File (.cdf).

I have a simple work-around: if I use Quartus 15-0-0 programmer, it works fine, and I don't get the error. (I'm using Quartus 15-1-2 to generate the .sof file)

Has anyone else seen this problem ?

Regards,

Chris
