Error: CONF_DONE failed to go high in device 1.

Before anyone comments on this, I have searched the forum and read everything I have found on the internet with people getting this error message. :)

I'll try to post as much relevant information as possible, so the next one who has this problem might get off a bit easier.

"Error (209014): CONF_DONE failed to go high in device 1"

The error message happens both when trying to program the Serial Flash Loader and when trying to program JTAG directly. The programming fails before there is any progress, it doesn't even say 0%.

Auto Detect Device functions as it should though. I get the choice between EP4CE15 and EP3C16, but that has never been a problem with other designs.

I have made a custom board with a FBGA256 Cyclone IV EP4CE15 fpga and some peripherals.

The fpga is hooked up with JTAG for Serial Flash Loader (SFL) as described in the Device Handbook on page 218 (figure 8-29, revision november 2011).

I'm using a 20MHz CMOS oscillator, although that shouldn't have any impact on this issue as far as I know.

The supply voltages are derived through separate low-noise, high PSRR LDO-regulators which can deliver max 150mA each.

They are connected as such:

VCCIO of all IO-bank is 3,3V.

VCCINT and VCCD_PLL is 1,2V.

VCCA is 2,5V

nCE (J3) is connected to ground.

nStatus (F4), nConfig (H5) and CONF_DONE (H14) are all pulled to VCCIO by 10k resistors.

MSEL are connected as MSEL0(H13)=2,5V, MSEL1(H12)=GND, MSEL2(G12)=GND. But since I'm using JTAG these would be overridden anyways.

The JTAG plug is connected as such:

1 - TCK (pin H3), pulled to GND by 1k

2 - GND

3 - TDO (pin J4)

4 - 2,5V

5 - TMS (pin J5), pulled to VCCIO by 10k.# modded this to VCCA.

6, 7,8 - N.C.

9 - TDI (pin H4), pulled to VCCIO by 10k.# modded this to VCCA.

10 - GND

Does anyone know anything I can try?

    Hi,

    the Conf_Done (High/Low) is taken by Boundary Scan, thus the status is "measured" w/o being physically connected to the JTAG I/F.

    Maybe it's worth filing a service request at ALTERA - perhaps you really found that magic MSELx combination...

    I did actually file a service request. The suggestion I got was to set the MSEL pins to a correct combination. Damn it!

    Hey, so you've got your instructions... Come on - take some tiny wire and do it, it's just only a FBGA... :-)

    (Sorry for the sarcasm)

    Well - based on the layout, perhaps you can use a small drill to open the connection of MSEL1 (H12) to GND by drillling the via (my Layout is somewhat standard and thus any Pad for the BGA is routed to a via crossing the complete board (no burried via). If your's is similar, maybe the internal weak pull ups will do the job to get the system running.. Ok - this still is not as recommended in the handbook (don't leave MSEL pins floating)...

    Except some additional minutes of worktime there seems to be less to loose, as the board itself in the actual configuration seems to be unuseable so far..

    Hehe, my thought exactly! :D

    Edit:

    Just so there's no misunderstanding, I didn't get any instructions from Altera until a few hours ago..

    Edit 2:

    Actually, I like your idea. I'll have to check if I have access to the tools though, but I'll try to give it a shot.

    I'm not sure the MSEL-pins will have a weak pull-up though, but it's worth a shot.

    Drilling the MSEL holes didn't help.

    Seems like I have to do a redesign after all.

    Ok, now you just have to use small, tiny wires, push them through your drilled holes and position them to contact all MSEL pin to GND - shouldn't be a "Mission impossible", should it?

    Just kidding :-)

    Hi again.

    This is coming a bit late, but I redesigned my PCB and made sure the MSEL pins were connected correctly for Active Serial programming. I also added a connector for AS, to be on the safe side.

    It works fine this time, so it would seem that it was only the MSEL pins that were incorrect.

    Apparently, when Altera wrote "JTAG-based configuration takes precedence over other configuration schemes, which means the MSEL pin settings are ignored." in the datasheet they also meant that another configuration scheme needed to be selected.

    Thank you so much for your help, Carlhermann! :)
