maybe i'm doing something wrong, or i failed to "read the instructions" properly.

i feel i'm asking a stupid question, but ...

if we program a nios-based design of our making in the cyclone evaluation board, it will only run for, roughly, 10 minutes.

it does not help that the board is connected through the jtag uart to the quartus programmer (tethered).

this applies to hal based programs and the uclinux os.

can anyone help, please ?!

This seems odd; are you sure your hardware is good? When it&#39;s tethered, the box in the programmer should say that it&#39;s connected to Opencore bla bla... otherwise, you will get an error saying that it lost communication. Maybe there&#39;s a problem with your JTAG that causes communication to be lost after 10 minutes? How are you determining that your program has stopped because of the tethere operation, and not a coding/hardware error?
