Unable to Write Using External Programming Adapter

[kiteboy]

Hi not sure if somebody can help
Just soldered up the external programming adapter and installed sthe TTL 232R Drivers FTDI Version 2.12.26.0 and its detected on port 3 fine
However when choosing the Arduino FIO in the IDE all I can get is the following using the Bare Minimum example script :

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x30
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x20
avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x30
avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x20
avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x30
avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x20
avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x30
avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x20
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x30
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x20

Tried various boards in the arduino IDE and also editing the boards.txt but when I do that I get an error as below

Warning: Board arduino:avr:sleepypi doesn't define a 'build.board' preference. Auto-set to: AVR_SLEEPYPI
Bootloader file specified but missing: C:\Program Files (x86)\Arduino\hardware\arduino\avr\bootloaders\ATmegaBOOT_168_atmega328_pro_8MHz.hex
Sketch uses 444 bytes (1%) of program storage space. Maximum is 30720 bytes.
Global variables use 9 bytes of dynamic memory.
Error while uploading: missing 'upload.tool' configuration parameter

Can somebody help - seems like a waste at the mo

Would love to get this working
Thanks

I'm facing the same issue (2 years after this issue has been filed without answer...) on a Mac with the latest version of Arduino IDE. The board is detected on the USB port, so it's in theory operational, but I can't upload anything.

Hi Bjoern, Sorry to hear that, I didn’t realise you were still having problems. By the sounds of it, the board isn’t being reset before upload - this can definitely cause those messages. This could very well be a hardware issue rather than software Mac / Arduino IDE issue. I’d first check the programming board that everything is soldered ok. If there’s nothing there, then you can try manually resetting the board using the small black reset button, at the point of upload - hit the Upload, then as quick as possible hit the reset (or try it the other way around as I think the bootloader is active for about 1/2 a second). It’s a bit of a juggling act and may take a few goes, but it can be done and that would then suggest a reset issue. Let me know if this sheds any light on it. Kind regards Jon

ok, I found the issue, it was due to an issue with the power supply. I exchanged it with another one and now it's properly uploading just fine.

Resolved for me.

I ran into a very similar error for over a year which I eventually figured out, I made an assumption that you didn't need to provide external power to the sleepyPi board while flashing which turned out to be wrong. Once I connected the micro USB, all was good haha.
