Beginner - what is wrong

[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.

@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.

[tbowmo]

Only thing that is left, that I can think about, is if itead had somehow forgotten to write the bootloader..

But then again, I have supplied them with a binary including both bootloader, and default sensebender micro sketch, so it should have the bootloader. Unless they have made some mistakes..

I haven't bought any sensebenders for the last couple of years, so unfortunately I can't verify this.

[zeroxdeadbeef]

Thank you for you input. I had luck and we have an AVRISP mk2 lying around in my company that I can borrow for the weekend. So my plan would be to try to re-flash DualOptiboot first or another bootloader (maybe the stock Arduino Pro Mini one) in further tries and see if this helps.

The only two things I am trying to figure out in this very moment are:

1. in which direction the ISP cable has to be mounted so that nothing is damaged
2. and I do not know yet for sure if the AVRISP mk2 is actually suppyling power or not to the board (for cases where e.g. it may feed 5 volts).

[zeroxdeadbeef]

Okay, I have soldered the second Sensebender too and tried to burn the bootloader via Arduino IDE onto both devices. The verbose log was the following:

avrdude done.  Thank you.

Interesting in this log is the warning about the invalid value for some fuse bits...

Flashing a sketch after re-burning the bootloader sadly did not work, the same not in sync error occured again. Next, I tried to burn the bootloader using the board setting of the Arduino Pro Mini (3.3v, 8mhz). Strange enough, this does not work anymore now, yielding a pretty generic error:

avrdude: stk500v2_command(): command failed
avrdude: stk500v2_program_enable(): bad AVRISPmkII connection status: Unknown status 0x00
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.

I do not know, I can only assume that maybe burning another bootloader does not work because of the invalid value warning while burning the default bootloader. I also tried to burn the original Optiboot without success.

[xmonika]

I just have this problem with "programming" solved. I bought this USBISP programmer, downloaded libUSBk drivers from here and pushed it into SBmicro via programmer USBasp. I don't know why but from some reason two UART programmers were not working.

It may save frustration and time to somebody in future.

[zeroxdeadbeef]

@xmonika

Thanks, I just ordered the same programmer. Let's see if this is working. How did you wire the programmer to the Sensebender? Just asking because the programmer has more pins available than the Arduino board.

[tbowmo]

@zeroxdeadbeef

the SB micro is using the standard 6pin AVR-ISP header.

Would be interesting to get a memory dump from a fresh SB micro that exhibits the problems with programming.. One of my theories is that it lacks the bootloader, or are misconfigured somehow from the factory.

[xmonika]

The programmer has 10 pins but the GND is presented 4x. Check the picture [here](http://www.avrfreaks.net/forum/adapter-program-10-pin-6-pin-socket-cable-computer-pc-led-reset-power for wiring, this is how I did it.

[zeroxdeadbeef]

Thanks for your responses. Sadly, both of my devices are not in factory state anymore. Nevertheless, I will report back after I have received this USBISP programmer.

[zeroxdeadbeef]

Hello!

Finally, I have received this USB programmer... I wired everything up, but flashing the Sensebender Micros does not work, sadly. According to avrdude they do not seem to respond:

avrdude: warning: cannot set sck period. please check for usbasp firmware update.
avrdude: error: program enable: target doesn't answer. 1 
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.

Error while burning bootloader.

I managed to program and burn the bootloader of a normal Arduino Pro Mini using this programmer and the same cable, so the programmer is working as expected.

[sincze]

Mmm i think I received a DOA... No pling pling sound in windows...
