no boot over nfs

Yes, you should not enable both jtag and uart as "support for console" in kernel config.

You should choose only one of them. see the wiki,

if you use serial uart (with a 9-pin RS-232C cable) on a terminal emulator such as minicom or ckermit,

[*] Nios serial support

[*] Support for console on Nios UART

[ ] Altera JTAG UART support[/b]

Do you have /dev/console ? I uploaded a rootfs which I used for the test.

In user config,

Core Applications --->

[*] init

[*] enable console shell

Then the init will open /dev/console for a shell.

If you do not select "enable console shell " or you do not have /dev/console, then you have to add a terminal to inittab.
