Hello I'm nev on this group and have following problem. I need to program EPM7064SLC44 using JTAG cable (ByteBlasterII) and Quartus
4.1 and it doesn't work Auto detection does not work either. When i connect EPM7128SLC84 all works, so cable and software is OK. I tried different chips (EPM7064SLC44 ones with different speed grades) and all don't work. i connected scope and TDI,TMS and TCK signals seems to be ok, but there is no TDO signal... Does anybody had similar problem? maybe there is something wrong with quartus? I used altera 7000 series chips and never had any problems (but never used 7064 one) Thanks for response Regards Greg- posted
