Having trouble flashing Ackmaniac firmware to FOCBOX

I am having an issue where I’m getting “motor detection failed” from ackmaniac ESC-tool during automatic motor detection/configuration. The motor will not spin even though everything appears to be connected properly.

This was after I tried flashing both firmware versions 2.54 and 3.101 to the FOCBOX. I read a thread by ackmaniac about the version 2.54.bin and when I try that one it the ESC-tool doesn’t even seem to connect to the VESC.

@kaaaaahle Kyle, From where you purchased your FOCBOX?

I purchased it from longhairedboy.com just a couple weeks ago

@CarlCollins What is Enertion’s policy on bricking a focbox exactly?

And is there a way to easily restore a FocBox from “bad firmware?” If it can be done easily, it may be worth putting together some kind of “FocBox Doctor” package for it.

think FISA (fuck it start again) is needed.

With the ackmaniac ESC-tool, reload the bootloader. Then reload 3.101 FW.

now make a quick video of your failing motor detection, explain you battery setup.

You might just be trying to perform a motor detection while outside of your working parameters (ie battery voltage cutoffs out of bounds) or you need to tweak your detection parameters.

I don’t think I bricked it. I’m still able to power it up and connect to it.

I’m gonna try again with firmware version 3.101 when I get home, I was getting confused because the “official” @Ackmaniac thread kept referring to downloading and flashing ackmaniac_2_54.bin.

That should probably be updated.

let us know how it goes!

That was before VESC-Tool came along.


The policy is same which I told you via Personal message

Would you mind sharing it with the rest of is? This is info a lot of us could use.

Can anyone help? There are multiple selections about which firmware to upload.

@Blasto @skatardude10 @longhairedboy

Focbox is 4_10&4_11&4_12, click that, then click default

sweet, it’s working now. Thanks so much for the help.

I had to increase the motor detection parameters w from 150 -> 400 and D 0.05 to 0.1 to get the thing to spin up properly.

Turnigy sk3 192kv. not sure about the build quality of these motors yet but we will see.
