Cyclone IV (EP4CE15E22C7N): CONF_DONE pin failed to go high in device 1

[Altera_Forum]

Hello everyone 

 I designed my first PCB with a Cyclone IV FPGA. Unfortunately, I can't configure the device.  Here's the log:    --- Quote Start ---   Info (209060): Started Programmer operation at Mon Feb 17 09:14:13 2014 Info (209016): Configuring device index 1 Info (209017): Device 1 contains JTAG ID code 0x020F20DD Error (209014): CONF_DONE pin failed to go high in device 1 Error (209012): Operation failed Info (209061): Ended Programmer operation at Mon Feb 17 09:14:15 2014   --- Quote End ---    I checked the signals CONF_DONE, nSTATUS and nCONFIG with a scope. During configuration, CONF_DONE is alway '0', nSTATUS and nCONFIG are always '1'.  Attached is the schematic, maybe there's a mistake I didn't see? As I'm waiting for the EPCS4 to arrive, this part is not on the PCB at the moment.  Thanks for the help.  Greetings Thomas

The package for this part has a ground tab (see this picture on the Digikey site):

Because your schematic symbol does not show the ground pin numbers, its not possible to determine if that is your issue.  Cheers, Dave

Thanks for the hint, but I soldered the part (including the exposed tab) with a reflow oven.

Now that you mention it. But I thought the MSEL pins are ignored if I use JTAG? 

Another thing I noticed: the pullups for TMS and TDI should be connected to VCCA and not VCCIO (http://www.altera.com/literature/hb/cyclone-iv/cyiv-5v1.pdf, page 211)?!  Thomas
