The Nios II data master is suppose to be connected to AVMM Slave of the jtag uart. Same goes with the timer.

You debug_reset_request in your Nios II should be connected to the reset of jtag uart. And disconnect it from the clk_in_reset and nios_ii_gen2_reset.

Refer to this: http://www.alterawiki.com/uploads/4/45/hello_world_lab_manual_max10.pdf and connect the debug_reset_request of nios ii to the jtag_uart_reset.
