on macOS I use the following sequence
499 cd /some_path/tgy-master
500 export A=/another_path/
503 export H=$PWD/bs_nfet.hex
513 make bs_nfet.hex
515 ls -l $H
516 (sleep 1; echo \\007; $A/bin/avrdude -C $A/etc/avrdude.conf -v -c usbasp -p m8 -P usb -U flash:w:$H )
use avrdude from within the arduinoIDE installation,
nothing special in the Makefile, I have avra installed as the compiler.
Does that help? For more info -especially with running on win - have a look at the first few posts of this thread

I have now build a hex file witch atmel studio 7 by using command line. And the i flashed this file witch avrdudess this is a gui for avrdude which only start avrdude with command line.
But i have still the same problem.

I have now ordered an usbasp stick. I will try it with them. Maybe the programmer that i use is the problem. i use a cheap one.

As far as I can see, it should be flashed with BlueSeries_40A_ ?
Or is this another type of ESC?

I tried to flash with an USBasp adapter and an Atmel Socket tool.
At first, there is a message with small size for bootloader, but it should be ok for BLHeli.

Then it writes and reads data, but afterwards I got the message from the third screenshot.
I think there is something wrong with the type or maybe the USBasp?

Thanks for your help :-)

Now it's working. I'd to use BlueSeries_30A_.hex.
I think the different current shouldn't be the problem, as it is not current-controlled?
hello. i'm interested in a small how to.
i have the same esc see in my earlyer posts. thanks.
