Can somebody please advise me on exactly which settings to use to flash HK-SS30A-HW ESCs? I've got the flashing tool from HK. When I place it on the chip the motor starts to beep but when I try to flash I get the "rc=-1" error. Im using the "atmega 8-based brushless ESC) controller... Thnx

Did you power the esc from a current limiting power supply? I never got it work to flash with the hk flash tool with direct powering from usbasp.

Hi Christian. No I havent connected anything else to the ESC, just the motor. Do I need to add any power to the other side and if so how many volts? I do remember reading somewhere to use low volts or something like that... Thnx

Anything from 7-12V is okay but it must limit the current. So put a car bulb in line with the battery if you have no adjustable power supply.

Thanks I will try that tonight. Just out of curiosity why would one need to limit the current during the process?

To not destroy the FET if you choose wrong firmware or something other went wrong during flashing.

It was posted by a contributor here - Simon K gave me a reference to it

And I think I have used it on an F30A and it worked. (I've done so much flashing and testing I've almost lost track of it)

I find that 5V generally works too. Has anyone found that 5V does not work?

I power my whole quad (4 ESC's with motors plus FC) with a 5V 1A supply when I flash them all.

A 9v battery is the simplest and easiest way I've found

Hey guys -

I am helping a friend who is about to flash some eRC 45a (Not opto-isolated) speed controls.

I have done a million eRC 35a ones (using bs_nfet.hex), and I have flashed several 65 and some 80a eRC ones (using bs.hex).

But I have not done the 45a ones. I see a nice picture in the first post of an eRC 45a speed controller, but no mention of which hex file to use! The pic was posted by SeismicCwave.

The reason for my concern is that someone posted in this thread that bs.hex did not work well with his ZTW 45a opto ESC, so he instead used bs40a.hex. I understand that the eRC esc's are rebranded ZTW's, so that is why I am concerned. But as I noted above, the ones my friend will be working on are NOT opto-isolated.

I don't want to toast one of these eRC45's, so: does anyone know which file to use?
