how to access the jtag uart in the nios code

I assume the HAL interface can not be used on a small footprint nios?

Is that correct?

If not, how should I do that?

Sorry for being a newbie with this.

I managed to get the following working:

#include "altera_avalon_jtag_uart_regs.h"
int i;
char c;
char h;
char s;
 
c = alt_getchar();
 
i= IORD(JTAG_UART_0_BASE, ALTERA_AVALON_JTAG_UART_DATA_REG);
alt_printf("\ni=%x", i);
h = i &  ALTERA_AVALON_JTAG_UART_DATA_DATA_MSK;
alt_printf("\nchar=%x", h);
s = c >> ALTERA_AVALON_JTAG_UART_DATA_DATA_OFST;
alt_printf("\ns=%c", s);

But when the characters are typed in to soon, it misses several.

For example:

if I type:

ABC

it can happen that the B is missed.
