New ContributorDear Sir,
Please find the attached schematic in previous reply.
The cards in which JTAG error is coming in that TDO is not coming. in this card CONF_DONE pin always high and NCSO is "LOW" after programming in AS mode and NSTATUS is LOW. NCONFIG once program started its becoming LOWfor some time and then HIGHuntill proram and after Program over in AS mode.
and in working cards NSTATUS during Program LOW and after Program over it is HIGH. CONF_DONE is during Program LOW and after Program over it is HIGH. NCONFIG once program started its becoming LOW for some time and then HIGH untill proram and after Program over in AS mode.
