I try to find a cause of a disfunction that stops a system : it occures at 1 min or lots of days after power-on.

Because JTAG can reconfigure FPGA, I prefer NOT plugging USB Blaster when the board is functionning. The risk is too important.

I made a "datalogger" board but it captures onl a few signals wich are not significant enough.

So I would like to offload data from Signaltap AFTER triggered (and after securizing the system).
