Error: JTAG ID code specified in JEDEC STAPL Format File does not match any valid JTA

Hi,

I am using Quartus II with 9.1 version.

while connecting to hard ware it is showing error like follows

Error: JTAG ID code specified in JEDEC STAPL Format File does not match any valid JTAG ID codes for device

and I coud n't connect to the hard ware,

details of hardware are as follows

family-MAX7000S

Device - EPM7256SRC208-15

thanks&regards

Has this ever worked - i.e. has your hardware developed a fault? Or has this never worked?

Have you check the power on the board? Is the device powered correctly?

Are you sure you are using a programming file intended for the device you're using?

What programming hardware are you using? Have you checked that the programming signals (TDI, TCK, TMS) are getting to the device? Is the device driving anything out on TDO?

Cheers,

Alex

I had the same problem. It worked one first time with a 7128STC100 on 2 different PCBs.

The hardware was beyond suspicion. Power ok, signals ok, programming file ok.

I got the same result with Quartus on Linux and Windows. Same result with a parallel port byte blaster.

I retested the USB byte blaster (clone) on a FPGA platform and the byte blaster was OK, even after plugging it in reverse a few times.

I specifically dedicated the JTAG pins for ISP in order to not brick itself after programming, but it seems something may have protected the access to JTAG.

Any hints?

Dear Alex,

The board has worked previously.

All impedences ,power connections on the board are proper.

Yes I am using programming file (.pof) it is intended for device,

currenlty we are using ByteBlaster II for programming hardware.

TDI,TCK ,TMS are getting to the device ,It is driving TDO also

while checking JTAG Chian at Quartus II it is showing uncertain TCK value.

thanks&regards

I assume you mean the frequency of TCK changes. This is perfectly normal and depends on many factors. Can I assume you have a good 3.3V swing on the signals?

Have you changed the computer you're using? Have you got a USB-Blaster to try? There shouldn't necessarily be anything wrong with ByteBlaster II, I'm just suggesting you try some other programming hardware, perhaps both computer & Blaster. I also suggest you upgrade to a newer version of Quartus.

Cheers,

Alex
