Cannot program ProMini 3.3V 8MHz with OS X El Capitan

Using Arduino Microcontrollers
1

Hi I have a problem, when I used Yosemite I could communicate to my Arduino ProMini 3.3V 8MHz configuration using Arduino IDE 1.6.5 with "Foca USB to Serial Converter (Foca USB to Serial Converter - CRCibernética)".

But now that I upgrade my computer to OS X El Capitan, there is an error in my IDE 1.6.5 that says:

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
avrdude: stk500_recv(): programmer is not responding

And it goes 10 times like that.

What can I do?

I am just trying to upload the blink example.

Thanks for your help.

Have you connected it correctly?

It doesn't have the normal 6-pin header, and the pins are in a weird order, so you'll need to use some care in wiring it up. If you think it's wired right, try swapping TX and RX (this is an incredibly easy mistake to make - I always try swapping those, even when I'm sure I got it right; It's susprising how often I didn't)

I finally could! :slight_smile: I install again the VCP Drivers - FTDI for my MAC and then Restarted it. Then I switch the TX and RX and It worked out!

Thank you so much DrAzzy! :wink:

The finally pin configuration is:

TX in FOCA --> RX in ArduinoProMini
RX in FOCA --> TX in ArduinoProMini
VCCIO in FOCA --> VCC in ArduinoProMini
GND in FOCA --> GND in ArduinoProMini
DTR in FOCA --> GRN in ArduinoProMini

So the first question to be asked was - "Apart from upgrading the OS, did you do anything else - such as perhaps, pulling the board down and reconnecting it?" :roll_eyes:

Same Error here :frowning:

I have shut down the "System Integrity Protection" via Recovery Partition an the Terminal.

Then i uninstalled the FTDI drivers as shown in this Document: http://www.ftdichip.com/Support/Documents/InstallGuides/Mac_OS_X_Installation_Guide.pdf

After reboot, i installed the Driver 2.2.18 (2012). But in the Dokument above is a new driver 2.3.0 (2015). I can not this new 2.3.0 version of the FTDI-Driver :frowning:

The 2.2.18 will not run :frowning:

Arduino says:

stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
avrdude: stk500_recv(): programmer is not responding

Sorry for my bad english :slight_smile:

Is there everybody, who can help me?
