Flowcode Support Board

I am going to buy flowcode but discovered a nasty error after some times it worked well.

Projekt is set to Arduino Uno, ComPort 6.
Device: ARD.ATMEGA.ATMEGA328P
Generated by: Flowcode v9.0.0.23

After compile to target i get allways the same errormessages:


C:\Program Files (x86)\Flowcode\Common\Compilers\avrv5\batchfiles\avrc_arduinoA.bat m328p arduino 115200 "C:\Users\Anwender64\Documents\FlowCode\Flowcode1.hex"

C:\Users\Anwender64\Documents\FlowCode>"C:\PROGRA~2\Flowcode\Common\COMPIL~1\avrv5\BATCHF~1\..\bin\avrdude.exe" -p m328p -P 115200 -b "C:\Users\Anwender64\Documents\FlowCode\Flowcode1.hex" -c arduino -D -U flash:w:""

avrdude.exe: invalid baud rate specified 'C:\Users\Anwender64\Documents\FlowCode\Flowcode1.hex'

Even sometimes another error is shown:
avrdude: ser_open(): can't open device "\\.\COM6"


It seemed that there is something wrong in the batch file or with Arvrdude.

The pc comport itself is working well witch I tested with external terminal program.
After the error I deleted Flowcode and the Arduino drivers as well as Avrdude from harddisk and cleard up the registry.
After new installation the same error is there.

By the way why is there no Arduino in the compiler options?
Only AVRISPII, E-Blocks and USBTiny are there.

Need Your help
Ulrich

Hello Ulrich,

This is a known bug and we have fixed it in the next pending update of Flowcode.

To solve the problem go into the Build -> Project Options menu and at the bottom right of the window click on the com port setting and assign your COM port. Even if it already looks selected it might not be so make sure you click the setting and assign the port.

Click OK and then compile to chip should then work correctly.

Thank you but it does not help anyway.

Still getting error

avrdude.exe: ser_open(): can't open device "\\.\COM6"

or

avrdude.exe: stk500_recv(): programmer is not responding
avrdude.exe: stk500_getsync() attempt 8 of 10: not in sync: resp=0x00

As allready mentioned the comport 6 is working well with an external terminal program.

Hello,

Please make sure the terminal program has closed the port before you try programming.

avrdude.exe: ser_open(): can't open device "\\.\COM6"

Means the programmer cannot open the port because it's already open in something else.

If Ben's advice does not fix the issue, next could you please try the attached.
Rename the file to avrc_arduinoA.bat and replace the one here ...
C:\Program Files (x86)\Flowcode\Common\Compilers\avrv5\batchfiles

Thank you, terminal program is of cause always closed after use

But in the meantime I solved the problem so far.

I do have a great bunch of different Arduino Uno and Nano boards.
I switched to some other uno boards from different suppliers.
About 50% of them do work with flowcode or the Arduino IDE, the others fail or work only sometimes.
Some with 16U2 converters on board work others not.
The same with CH340 converters.
Very strange that all of the boards do well with external terminal program.
I seems to be a big driver problem but not your fault.

I will investigate further in the driver problem.

Best regards
Ulrich

I'm having this same problem, using an "Arduino Uno", "Arduino Micro" and "Arduino Leonardo". They all give the same errors, sometimes the log below and sometimes the "invalid baud rate" error. Maybe there is something wrong with my compiler options?

Could you check your Flowcode version is up to date, use the "? About" button, top right.
And check you have done a "Full Database" update from the "Library Updates" button

Hi LeightM

I'm using V9.1.0.27 with full up-to-date database. The Arduino's are working, tested with the Arduino IDE.

Could you tell me what compiler options I should use?

Do you know what the baud rate should be for your devices?
Some clones do vary.
Perhaps the Arduino IDE has more variants support than we have at present?
