NIOSV firmware stuck when juart-terminal is not open for the print messasges.

Hi prashant_gohel​,

Can you try to modify the alt_sys_init.c?
Our team found that the current auto-generated initialization sequence is causing the JTAG UART fast driver to malfunction.

Current (Failing) - Nios V processor is initialized last.

void alt_sys_init( void ) 
{ 
    ALTERA_AVALON_JTAG_UART_INIT (JTAG_UART, jtag_uart); 
    INTEL_NIOSV_M_INIT (NIOS, nios); 
} 

Modified (Passing) - Nios V processor is initialized first.

  void alt_sys_init( void ) 
{ 
    INTEL_NIOSV_M_INIT (NIOS, nios); 
   ALTERA_AVALON_JTAG_UART_INIT (JTAG_UART, jtag_uart);  
} 

We believe that the JTAG UART initialization have some dependency on Nios V processor initialization.
As such, Nios V processor should be the first to initialize.
