FTDI Friend + extras - v1.0

[Juggler00]

A n00b question: Will the FTDI Friend allow me to program the new Arduino Ethernet with PoE Module (http://store.arduino.cc/ww/index.php?ma ... cts_id=142)?

cheers,
J.

I don't have an Arduino Ethernet in-house yet to verify, but it should be compatible.

It can be programmed like an Uno via a six-pin FTDI -style serial connector. The Arduino USB 2 Serial adapter or any FTDI-style USB-to-serial connector can be used to program it.

thanks!

Have you confirmed that the FTDI Friend can be used to program the Arduino Ethernet? I am not having any luck with the ones I just received. I'm using the Arduino 0022 IDE and the drivers that come with that. Windows XP recognized the FTDI Friend as expected but uploads are failing with the following errors.

avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

I'm about to order a USB FTDI TTL-232 cable to see if that makes a difference.

Thanks!

[adafruit_support_bill]

The FTDI Friend and the cable should be equivalent if they are both correctly wired.
How are you powering the Arduino when you attempt the upload?

If you hold the shift-key down when you press the upload button, there will be additional diagnostic output in the IDE.

we had no problems uploading to an Ethernet Arduino with the FTDI friend. be sure to select the right com port, UNO type board and the cable is plugged in properly

I'm using a 12V 2A supply to power the Arduino Ethernet

Here is the verbose upload output:

I'm using the same environment to upload the same code to an Arduino UNO with an Ethernet shield successfully.

[adafruit_support_bill]

You are getting no response at all.
Does your computer recognize the FTDI Friend when you plug it in?
Are you sure you have the right COM port selected? If it does not disappear from the menu when you unplug the FTDI Friend, then it is not the right COM port.

[RoysterBot]

Yes. The computer recognizes the FTDI Friend as expected. The COM port comes and goes goes as it is connected and removed. Once I receive the USB FTDI TTL-232 cable I have ordered I will try that with another yet untouched Arudino Ethernet to see if I might have a hardware issue with the one I'm working with now. I'll post an update once I try that.

Thanks!

I get the same exact results when trying to upload to the Arduino Ethernet using the USB to TTL Serial cable as I do with the FTDI Friend. I have tried two different Arduino Ethernet boards. I have tried two different Windows workstations, one Windows XP and one Windows 7. I have tried rolling back the FTDI drivers and re-installing the latest released drivers (2.8.14) without any luck.

Is my assumption that the Arduino Ethernet ships with a bootloader installed correct?

Thanks!

[adafruit_support_bill]

Are you able to upload to either board with a standard USB cable?

[RoysterBot]

Can you elaborate? There is no USB connection on the Arduino Ethernet so I cannot use a standard USB cable to upload with. That is why I have to use the FTDI Friend or the USB to TTL serial cable.

[adafruit_support_bill]

You are correct. I thought they had a mini plug on them, but I guess not. I just pulled one out to see if I could reproduce the problem. I'll let you know what I find.

[RoysterBot]

It looks like the Arduino folks have identified a timing issue between the bootloader and some FTDI cables. Here is a link to the thread I found. I have included the post from Massimo Banzi from that thread below.

Thanks,

(i'm reposting this from a different thread for semplicity)

Just a quick update of our current tests..

We have been testing a large number of boards with a 5v ftdi cable..
In a set of 40 boards 5 had issues with the cable...
It's a timing issue between the bootloader and the cable.
I guess that the timing issues are within close reach of the tolerances that any circuit has therefore only some boards have that problem.

Those boards work ok with the USB2Serial module that we manufacture.

We are now testing an updated bootloader that seem to solve all the timing issues.
We'll port an official solution on the blog after we have determined that the bootloader solves the issues.

thanks for your patience

In my test here, it worked fine with a direct connection, but had about a 30-40% upload failure rate going through a usb hub.

I guess we wait for the updated bootloader from the Arduino team. Thanks for posting the details.
