If I use UART4 to connect, then the screen will print lots of " � ", is it correct?
Thanks.

louisom · 2017-03-07T02:44:31Z

I think the answer is NO.

Could you give me the info about your board and the setting in the user/apps/build.mk?
Because if you are using STM32F429, and building with LCD apps, you may hang by this process, and got the junk info like you got.

gnitnaw · 2017-03-07T09:44:02Z

I didn't change the code (with stm32f429 discovery). All are the same (git pull yesterday).
I connect to USART4: PC11 (TX), PC10 (RX)
Here is the message after I push reset button:

====================================================
Copyright(C) 2013-2014 The F9 Microkernel Project

About LCD apps, I can see the rectangle on the LCD.

louisom · 2017-03-07T09:56:41Z

You still need to check user/apps/build.mk, my setting is like this

# Copyright (c) 2013 The F9 Microkernel Project. All rights reserved.
# Use of this source code is governed by a BSD-style license that can be
# found in the LICENSE file.

user-apps-dirs = \
	l4test \

If you use default setting, it may contain other apps.

And if I remember correctly, UART output will use async output, so your kernel may occure some problem after __l4_printf(banner) when init with INIT_LEVEL_KERNEL_EARLY hook at start.c.

Maybe you can use gdb to trace it.

After I remove the ping-pong in user/apps/build.mk, it becomes:

So how to solve this problem?

What is your current baud rate? 115200 or 9600 gnitnaw <[email protected]>於 2017年3月7日週二，下午6:16寫道：

I have tried 115200, 76800, 38400, 19200, and 9600.
Only 115200 can let me see the banner...

louisom · 2017-03-07T10:23:20Z

@gnitnaw Can you give me your .config?

I assume you use minicom to see the output of UART. So, do you have turned off (or turned on) software flow control and hardware flow control ? gnitnaw <[email protected]>於 2017年3月7日週二，下午6:25寫道：

No, I simply follow your instruction:
sudo screen /dev/ttyUSB0 115200 8n1

louisom · 2017-03-07T10:36:44Z

That's weird. Using your setting with master (d466fe1) branch, I can get the output:

@gnitnaw For now, I know you have tried USART1, UART2 and UART4 but it doesn't work normally.

Hence, I suggest you to read the document STM32F420 Note at this moment, please pay attention 「示範專案：USART 測試程式」, which is a part of the document.

If it doesn't work, I suggest you change your USB TTL Cable.

gnitnaw · 2017-03-07T13:33:49Z

For me USART1 works... USART2/4 doesn't work.

ab1aw · 2019-03-05T12:11:12Z

Are you also using the LEDs? The LEDs and the USART4 (PA0 and PA1) are using the same GPIO pins. Take a look at my ping-pong and other apps on my fork to see working variations of user/apps.
