Can I use jtag instead of writing code for lcd

Hello all, I have a custom board with Cyclone II and NiosII implemented. The system is interfaced with a sensor and with an lcd module.

I use the lcd module included in SOPC builder .

I developed a program that reads data from a sensor.

In BSP editor I selected the lcd module as Nios II standard out console to visualize Jtag information.

So all my printfs goes to lcd. Its working Ok.

I would like to ask if I can use in my final project the JTAG module in order to visualize the relative printf s or I have to implement a the piece of code that will control the lcd module.

I read in forum that it could not be used JTAG output in final projects because there will be a problem flashing them!

Can I leave Jtag module and flash the board from the moment I will not use it for sending data outside direction (I mean Eclipse in the Personal Computer).

I hope that is clear what I mean! Please forgive my English.
