Guys

I'm going home with a problem unsolved.

After an ALTERA EPM570F has been programmed can it still be boundary
scanned using the original BSDL file or does the fact that IO pins are
now hard wired as Input or Output mean that they can only be scanned as
Inputs or Outputs. (nneding the BSDL to be changed).

I have spent an hour on the ALTERA website and it is not at all clear.
In some places it suggests that ISP is the last JTAG thing that would
be done.

Apologies for perhaps being very slightly off topic but a simple yes or
know from someone who knows is all that I'm hoping for.

Regards

Colin

Hi Colin,

    In the Assembler settings tab, select 'Always enable input
buffers' and recompile the design.

Hope this helps,

Thanks for saving me a lot of time. Allthough putting it right is going
to take lots more!

Unfortunately the firmware has been formerly released by a third party
in the US and I have to prepare it for volume manufacture in the far
east and I work in the UK.

I will go and check, but I think that all the "errors" were stuck at
ones. Is the result that should be expected?

Allthough you have saved me some considerable time could you tell me
where the designer should have found this info. If it's very obvious
then I will have a quiet word with him. If it's not in a very obvious
place (and I have spent longer than I feel I should have looking) then
perhaps you could have a quiet word with your technical authors.

Regards

Colin
