Honored ContributorI have bought a Nios II Development Kit(2C35) . It often reset automatically when I communicated with Computer through Ethernet . I do not know why? Who can give me some advice?
Honored ContributorA random guess is that if you have a completely full design, I would look at if hte power supply is being taxed and resulting in a reset?
Just a wild guess.Honored ContributorI know NIOS II kits reset itself after configuration if you set the unused pins to drive ground. This is because the nConfig pin is tied to one of the unused IO. Not sure what happened to yours if it reset because of connection to PC using ethernet.
Maybe you can try to set the unused pins to be input tri-stated and see if it helps. Driving ground sometimes draw a lot of current as well if you have pull up resistors to the unused pins.Honored ContributorHi Avatar and LTS,
Thanks for your reply. I have a new discovery. In fact, the problem is the ethernet at Nios II Development Kit(2C35) was broken and then connected again when I send a string from PC to Development Kit sometimes. It cause my command lost. Are there any defects in lwIP ? How can we solve this problem? Regards, Jnwang
