Hi everyone, I'm doing some work with custom cyclone III boards and am in the process of trying to program the device using a JTAG port and a USB Blaster cable. The boards were used last yea...

Sorry it took so long to reply I've been super busy. You select AS programming in the drop down box of the programmer, where you currently have JTAG programming selected. For me this removed the current device I had set up as the device was not supported via AS programming. So I had to add a new device, as for the device number I couldn't help you because the one I used was listed in our own documentation with no reason given, but I would suggest to check the data sheet, it might list which device to use in AS mode or something like that. PS, this will only work if your board has been configure for AS programming so check the data sheet and compare against your boards schematics to see what mode it was configured for. Sorry I couldn't be more help, Mat.
