Beginner - what is wrong

[xmonika]

@tbowmo In IDE (Arduino: 1.6.13 - Windows 10), I have: "Sensebender Micro, Atmega328 8Mhz" (it is also shown in the code above) is that correct configuration?

[tbowmo]

@xmonika

And you can successfully see the debug log in your terminal program, from your sensebender micro?

[xmonika]

@tbowmo Yes, i.e. now I can see in the terminal all this:

[tbowmo]

@xmonika and still you can not upload a new sketch to this Pcb?

[xmonika]

@tbowmo Yes, exactly. By pressing Project Upload => not in sync and Upload error. By pressing Project Upload via programmer => just Upload error message. Here is my setup

[tbowmo]

I'm out of ideas right now.

Did you try a more recent version of the arduino ide?

[xmonika]

@tbowmo I will try to install all the drivers & IDE on diferent comp tomorrow. I already did the downgrade from 1.8 because of the note "Arduino IDE 1.5.x & 1.6.x compatible." in SB tech specs.
Anyway thanks for your help. I will have to invest more hours yet to reinvent the wheel but it is fine to have somebody to consult with.

[tbowmo]

@xmonika

Hmm.. it should be compatible with anything above arduino 1.6.. But it's a while since I compiled anything for that target (all my sensebenders have been in "production" since june 2015)

[xmonika]

So I have tried it on the different computer and the results are the same.

This is what I did:

• download ide 1.8 here https://www.arduino.cc/en/main/software & install
• download CP CP2102 win 10 drivers here https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
• install mysensors libraries in IDE via manage library internal tool
• add https://raw.githubusercontent.com/mysensors/ArduinoBoards/master/package_mysensors.org_index.json to IDE
• select Sensebender micro board, COM6 (the only available), Programmer AVRISP.mkII
• add necessary libraries to compile the sensebender micro sketch as described here https://www.mysensors.org/about/arduino#optional---install-external-mysensors-examples - via creating zip files and add zip library file to sketch. Necessary libraries were SI7021 + sha204 + RunningAverage
• compile and upload the basic sketch from here https://www.openhardware.io/view/1/Sensebender-Micro

Result is: stk500_getsync() attempt 7 of 10: not in sync: resp=0xdb

[tbowmo]

@xmonika

Wait a moment, you choose AVRISP.mkII ? That shouldn't be necessary, as it is only needed if you ever want to upload a new bootloader (and then you need a different programming adapter as well)

You are using the build in arduino programming tool to download? (Second icon from left, in the top menu)

[xmonika]

@tbowmo Yes, second icon from the left (or Ctrl+U).
By pressing Project Upload via programmer (in menu Project or Ctrl+Shift+U) the result is little bit different - no stk500_getsync() attempt 7 of 10: not in sync: resp=0xdb error just uncommented Upload error.

[tbowmo]

@xmonika

When you have chosen SenseBender Micro as target, which sub variant did you choose? (8Mhz, or 1Mhz?) Can't remember if there are any differences in baudrate.. And I'm not at my arduino dev. machine right now. You should choose the 8Mhz as target.

Also could you check soldering of the board? (specially around the reset line, capacitor, resistors, atmega328)

That is the last things that I could think about right now..

[xmonika]

I have selected 8 MHz. This is what it looks like by me

This is what I did today - got another sensebender micro (SBM) board, soldered jumpers, connected again. Then I measured the conductivity between DTR pin on CP2102 chip and capacitor on DTR wire on SBM. It shall be conected via my wires and it was correctly connected.

Then I run the compillation again and the result is the same - not in sync. So I feel I have replaced everything but still getting the same error.

[Nca78]

@xmonika do you have an arduino board ? You could try to use it to test your serial adapter.

[xmonika]

So I tried Arduino nano (may be clone). The result is simillar - not in sync. But then I tried the nano via standard mini USB cable and also not in sync. Possibly WIN 10 related? I tried it with admin privileges.

[tbowmo]

@xmonika or it's related to your usb 2 serial interface?

[xmonika]

Could be but the same I get on my second computer (win 10 as well). Will experiment with that.

[tbowmo]

But still using the same USB device on the second computer?

Hello!

I was hoping I would find a solution here as I basically have the same problem. I ordered two Sensebender Micros like two months ago and flashing a sketch onto them is failing with the same avrdude: stk500_getsync() attempt X of Y: not in sync error. (Noteworthy: I only assembled one Sensebender so far, I haven't tried the second one).

In my case: I am using ArchLinux with kernel 4.13, so drivers should not be the issue here. I am using this FTDI flash module and the same USB cable for other projects and was able to successfully flash an ESP 8266, a Arduino Pro Mini and a Nano.

Executing the self-test on the Sensebender Micro does also work and with serial attached I even get the output that all tests have passed. Still, i am not able to flash something onto this device using the IDE. Instead of selecting the board option Sensebender Micro (using both 8 and 1 MHz options) I even tried some odd choices like Arduino Pro Mini or Arduino Nano. Nevertheless, none of those did work.

Regarding FTDI to Sensebender connection: VCC <-> VCC, GND <-> GND, RX and TX are swapped. I even tried replacing the cables and tried to connect DTR without luck.

Any further hints are appreciated, thank you.

[xmonika]

Unfortunately I didn't solved it, I just gave it up and am waiting for new ISP programmer to arrive. That is the last piece I didn't changed (I have changed computer/SW, sensebender Micro and it didn't helped). Hope you will be more successfull.
