STM32F407VE hang up using USB Serial(CDC) with 6 serial on.

Hi there guys,
As the title implies, if I combine all the codes to run the six uart/s and USB Serial(CDC) the program hangs up and stop sending the debug message.
Please suggest any thing that I can do with the code or is it something to be changed in the core?
No error encountered during compilation.
Im Using:
OS: Windows 10
IDE : Arduino IDE 1.8.10
Core : StevStrong core (
https://github.com/stevstrong/Arduino_STM32)
Board settings: Generic STM32f407V series
USB Configuration: USB Serial (CDC)
Upload method : ST link (im using jlink to upload the bin file)
Here is my sample code:
Code: Select all
void setup() {
Serial.begin(115200);
Serial1.begin(152000);
Serial2.begin(152000);
Serial3.begin(152000);
Serial4.begin(152000);
Serial5.begin(152000);
Serial6.begin(152000);
delay(1000);
Serial.println("Start");
}
void loop() {
// put your main code here, to run repeatedly:
if (Serial.available() > 0) {
Serial.write(Serial.read());
}
delay(1000);
Serial.println("USB Serial Test tx");
// delay(10);
Serial1.println("Serial1 Test tx");
Serial2.println("Serial2 Test tx");
Serial3.println("Serial3 Test tx");
Serial4.println("Serial4 Test tx");
Serial5.println("Serial5 Test tx");
Serial6.println("Serial6 Test tx");
}

try a debug?
or did you try commenting the serialX to see where the 'hang' occurs?

Thanks for your suggestion
What I have tested is,
1. Use only the USB serial (Serial) --> result does not hang
2. Use USB Serial(Serial) and added Serial1 --> result does hang
3. I just added all the serial and USB Serial(Serial) --> result does hang

tried
instead?
152000 seemed quite odd a baud rate, but nevertheless, stm32's uart tend to still work with odd baud rates
i actually tried successfully to connect esp8266 at 74880 baud on stm32f103
to dig into the bottom of it one may need a debugger
some alternatives are to Serial.print() to the usb-serial console to try to figure out where it got stuck
it is quite possible to do that with gdb / openocd / st-link-v2
https://ardupilot.org/dev/docs/debuggin ... stm32.html
then there are 'full suite' setups patched into eclipse etc e.g.
https://www.openstm32.org/System%2BWork ... or%2BSTM32
https://github.com/stm32duino/wiki/wiki/How-to-debug
one other trick that i tend to use
are things like
Code: Select all
void blinks(int8 led_pin) {
bool led = true;
for(int i=0; i<10;i++) {
digitalWrite(led_pin, led);
led = ~led;
delay(100);
}
}
then i called blinks deep into various codes to see where it reached, you could literally try different blinks() patterns and different leds

the baudrate is quite wrong, its my mistake to make it 152000, it should be 115200. Thanks
I tried to put debug message in each every line to see where it got stuck. It get stuck after sending from Serial then Serial1.
BTW, I got to make it work now, I downgraded my arduino IDE to 1.8.9 and it works perfectly.
I also created a test code. see below.
I'm just wondering why this code is not working in 1.8.10 and it works in 1.8.9.
Thanks.

btw i tend to work in eclipse and used a makefile.
between the releases, the way it (Arduino IDE) reads platform.txt and boards.txt may have varied, if it fails to do like previous, it could have an impact
this is a recent makefile i used with f401 black pill
viewtopic.php?f=47&t=37&p=328#p327
this is an old makefile i used with f407
viewtopic.php?f=47&t=37&p=328#p328
if you work in windows, you probably need WSL to use the makefiles. u'd need the linux arm-none-eabi gcc stacks too installed in the linux environment

oh..good input
I learned something new with you.
Well i dont know how to make a makefile as I have encountered it a lot of times.
Maybe @stevstrong should check this out so it will work on 1.8.10.

working in eclipse has one thing i liked, it can search and jump from symbol to symbol / function referenced etc
so it is easy to do a 'deep dive' e.g. from Serial1.print() i can drill down into print etc to see where are the codes
the 'bad' thing about eclipse and possibly even Arduino IDE, is that the configs (defines, includes, sources, compiler flags and library paths) are set in the GUI. especially in eclipse (without nice plugins like sloeber
https://eclipse.baeyens.it/), i've had to redo all my defines, includes, source paths, and flags with each new sketch/project. that is 'painful'.
in the end i used makefiles instead

I can reproduce the issue, please wait for a solution I will post on Github.
