 Bigger Bigger  Smaller Smaller  Reset Reset

I just received 2 Arduino Ethernet boards and non of then seems to function correctly. I'm using FTDI cables from Sparkfun, IDE ver 0022 and running on Win7 64bit (and 32bit). When I try to upload a sketch I always receive the following error:
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

Yes, i have updated the Boards.txt file with setup for the "Arduino Ethernet" board and it is selected before upload. If I start the Serial monitor and push reset on the Arduino board i receive "Reset done." so I guess the FTDI cable works correctly.

I have tested on several computers with the same result. I have tested to push reset just before (and after) starting download.

Is it any way to check that the correct bootloader is loaded in to the board? Or is it any error in the Boards.txt setup?

this is the setup I use:
##############################################################
uno.name=Arduino Ethernet (with USB2Serial module)
uno.upload.protocol=stk500
uno.upload.maximum_size=32256
uno.upload.speed=115200
uno.bootloader.low_fuses=0xff
uno.bootloader.high_fuses=0xde
uno.bootloader.extended_fuses=0x05
uno.bootloader.path=optiboot
uno.bootloader.file=optiboot_atmega328.hex
uno.bootloader.unlock_bits=0x3F
uno.bootloader.lock_bits=0x0F
uno.build.mcu=atmega328p
uno.build.f_cpu=16000000L
uno.build.core=arduino
##############################################################

Any suggestions?

Do you have the FTDI cable connected the right way around?

Guess so. Black wire to the BLK marking on the board. The On and L9 LED are lit and as I wrote, I receive an "Reset done." message in the Serial Monitor a few seconds after pushing the reset button

Hello,

I reprogramed the bootloader, i select the same bootloader like a duemilanove with at328, when i select the board in IDE i put duemilanove and com port of FTDI 5V cable, all work ok.

Factory bootloader error? boards.txt error?

Please, gurus of arduino, help!!!!!!!

Hello,

I don´t know exactly.

I connect an usb tiny avr programer, select arduino board Duemilanove with at328 and burn it.

Now if i used it like a Duemilanove, it work, included ethernet.

If i look into hardware folder of IDE i can see a lot of bootloaders, i tried to find a list of Arduino boards <-> Bootloaders used, but i can´t find it.

I hope it help you, if i get more info, i put it here.

I tested the same but uploaded the bootloader with a avride mkII programmer and now the board is totaly bricked.... smiley-sad

Even if the upload software (Arduino IDE) says "Done burning bootloader"

The power led and the L9 led are lit but its the only visibly sign of anything. Nothing happends wen pushing the reset button and no message in the serial monitor. A strange thing is that the ethernet chip get quite hot after 30 sec or so. ??? I think i need to return both boards to the store, mayby it was some hardware error right from the beginning.

hello,

It is true, the ethernet chip get hot very fast.

i believe this board need a revision of design.

i don't know how is your programer, but i think if you get an ok and L9 go up, now the problem is comunication pc <-> arduino, are you tried with the last drivers from FTDI.

until I know, when the IDE want upload a skecht to board, the first it do is reset the board.

When you try upload something you can see the led l9 go off and go on?

did you try to make a reset just in the moment when the upload begin?

Are you try to burn other bootloader?

Seems there are a few people with the same issue on this board, me being one of them.

There are a few threads, this being one example: http://arduino.cc/forum/index.php/topic,67777.0.html

(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

Many thanks for your reply.

Is there a time scale for this solution.

I have had the board almost a month now with one RTM already and still no joy in getting it working.

Will the updated Bootloader be something that I can install or will it be another RTM ?

Thanks again for your efforts.

Many thanks Massimo - I've hit exactly the same problem using the FTDI Cable with Arduino Ethernet (but this time from SuSE linux), so would really appreciate the fix!
