Here is my 'hello':
#include <stdio.h>
int main(void)
{
int i=23;
printf("Hello, eCos world! %i\n",++i);
++i;
return 0;
}
It seems that target console output do not pass through 'mangler'.
With the diagnostics output directed to the channel 0, the "$O..#" message, can be seen on the host.
#include <stdio.h>
#include <cyg/hal/hal_arch.h> /* CYGNUM_HAL_STACK_SIZE_TYPICAL */
#include <cyg/hal/hal_if.h>
const char test_string[] = "$O5468697320697320612074657374206d657373616765210d0a#12";
int main(void)
{
int i=23, cur;
cur = CYGACC_CALL_IF_SET_CONSOLE_COMM(CYGNUM_CALL_IF_SET_COMM_ID_QUERY_CURRENT);
CYGACC_CALL_IF_SET_CONSOLE_COMM(0);
printf("%s\n",test_string);
CYGACC_CALL_IF_SET_CONSOLE_COMM(cur);
printf("%s\n",test_string);
i++;
return 0;
}
Target dies after the second printf.
