Flowcode Support Board

So - this is probably related to other issues - but couldn't find the topic If one of the other VCs wants to move this across then please do...

I tried to program an Arduino Pro (maybe it's a mini?) 3.3v. This doesn't have a USB port and programming is via a FTDI convertor.

Anyway - using the Pro mini 3.3v seems to use 19200 baud and 168processor - so no joy. Swapped to Pro 3.3v (328) and tried again - here I got the dreaded 'can't open COM6' error (which has been mentioned before - can't open //./com6)

I copied the command line and tried to find where the problem lies. (Using a simple 1s flasher as an example)

"C:\Program Files (x86)\Flowcode\Common\Compilers\avr\bin\avrdude.exe" -p m328 -P com6 -b 57600 -c arduino -D -U flash:w:"flash.hex"

- is where the problem lies.

There are two issues here
1) need -p m328p (not m328) - a fcdx problem? The clock is also force to 16MHz - where the 3.3v version is 8MHz
2) The serial port issue - this fails with 'cannot open serial port //./com6' - however - simply removing the space before com6

-PCOM6

works perfectly. Adding the space back - stops it working.

However - I'm not sure why, since AVRDUDE should ignore the space. - but the two changes make programming reliable in this case. Would it be possible to do a test to one of the fcdx files / one of the batch files to see if this fixes the problem.

As mentioned above - someone else had reported this (couldn't open com4) ...

Very interesting.
We'll pick this up on Monday

It's strange - I modified: avrc_arduinoA.bat -

:ProgFlash
@SET AVRDUDEcmd="%~dp0..\bin\avrdude.exe" -p m328p -P%ComPort% -b %BaudRate% -c %2 -D -U flash:w:"%FileName%"
@SHIFT
@GOTO Send

:Config
@SET AVRDUDEcmd="%~dp0..\bin\avrdude.exe" -p m328p -P%ComPort% -b %BaudRate% -c %2 -u

So I'm forcing a m328p MCU (which obviously isn't great) and getting rid of the space after -P (it was -P %ComPort%).. This works well - allowing upload from within Flowcode (tested in v8 - but the problem persists in v9 so hopefully the same fix should work...)

I looked at modding one of the fcdx files - but there is one mighty CRC at the start of the file, I'm worried that I'll break something...

Thanks Martin
Modding an FCD won't break anything.
Flowcode just uses the checksum to mark the file as non genuine
