The problem is in avrtest.c:335
static int data_read_byte_raw(int address)
{
// add code here to handle special events
if (address == STDIO_PORT)
return getchar();
return cpu_data[address];
}
address happens to be 82 which equals STDIO_PORT, therefore avrtest
waits for input. I removed the if and avrtest works as expected; the
test program hits ABORT in the remainder.
