now,after i program the flash,i can open the nios2 terminal ,it show message:
<div class='quotetop'>QUOTE </div> --- Quote Start --- [SOPC Builder]$ nios2-terminal nios2-terminal: connected to hardware target using JTAG UART on cable nios2-terminal: "ByteBlasterII [LPT1]", device 1, instance 0 nios2-terminal: Warning: The JTAG cable you are using is not supported for Nios nios2-terminal: II systems.

this whole work has three steps(i use ecos for nios2):
1)nios2configtool config the jtag uart as console device; 2)program_flash hello to my board,it succeed! 3)open nios2 sdk shell and run nios2-terminal to receive the "hello world" message. when restart the board,i can't use nios2-terminal to connect to my custom board,is it the sopc custom problem?whether do i must custom the target board again?
