急！！我疯了 connected, target, button, 程序, hardware

jojolee

一个简单的hello_world程序

为什么总是出现这个nios2-terminal: connected to hardware target using UART on /dev/com1 at 115200 b
aud
nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)

我到底应该怎么做？才能看到我输出的东西？？

这个是nios2-terminal命令行提示啊，没有问题啊。

如果楼主要输出自己的数据，可以使用比如 fprintf(uart, "open flash device failed!!!\n");

int main(void)
{
alt_flash_fd* flash_handle;
FILE *uart;
char write_data = 0;
char read_data = 0;
write_data = 100;
uart = fopen(UART_NAME,"w");
flash_handle = alt_flash_open_dev(CFI_FLASH_NAME);
fprintf(uart, "open flash device...\n");
usleep(10000);
if (flash_handle)
{
fprintf(uart, "open flash device successed!!!\n");
usleep(10000);
alt_write_flash(flash_handle, DATA_OFFSET, &write_data, 1);
fprintf(uart, "wirte_data = %d\n", write_data);
usleep(10000);
alt_read_flash(flash_handle, DATA_OFFSET, &read_data, 1);
fprintf(uart, "read_data = %d\n", read_data);
usleep(10000);
if(read_data == write_data)
{
fprintf(uart, "flash write and read successed!!!\n");
usleep(10000);
}
else
{
fprintf(uart, "flash write or read failed!!!\n");
usleep(10000);
}
alt_flash_close_dev(flash_handle);
fprintf(uart, "close flash device...\n");
usleep(10000);
}
else
{
fprintf(uart, "open flash device failed!!!\n");
usleep(10000);
}
}
