When I use the byteblasterII to download my software in the NiosII_ide->Run,it appear

nios2-terminal: Warning: The JTAG cable you are using is not supported for Nios

nios2-terminal: II systems. You may experience intermittent JTAG communication

nios2-terminal: cable or another supported cable. Please refer to the file

nios2-terminal: errata.txt included in the Nios II development kit documents

YEP.

To use JTAG you must use the USB blaster rev B. There are some problems when you are using the rev A.

If you are using a custom board, pay a real attention on the JTAG connection : pullups, wire size.

To make my JTAG working I had to change pullups from 10KR to 1KR and add a 32R serial on the JTAG clock.

I use the ByteBlaster II (LPT) and it seems to work fine most of the time (download, debug...). For more information you really should read the errata.txt.
