Imax B6AC program with Arduino ISP

[Romeo Virgilio]

Hi all, i`m new here.

I need to charge LiHV (Lipo at 4.35 Volts per cell), so I decided to update the stock firmware to this one that can manage these lipos.

So I used an Arduino 1 to update but I had some problems.. I tried and this is the result:

Can anyone help me please?

Flashing itself seems to be successful. What is the problem?

Can you verify that contents of your hex file looks like this? (Sometimes, people download hex file incorrectly.)

Oh, I've spotted the problem, signature 0x1e950f means, you have flashed ATmega328P (your arduino) instead of charger.

Yes, flash your charger instead of arduino...

You did not provide any details about how you executed avrdude (arguments) nor details of wiring. Here is page about using Arduino as ISP. Without any additional info, I can't help you...

[Romeo Virgilio]

I programmed Arduino uno with ArduinoISP sketch, then I soldered 6 cable to my IMAX and connected with Arduino, mosi-13 miso-12 sck-11 reset to reset, 5V to 5V and gnd to gnd.
After that I downloaded AVR DUDE and I follow documentation to flash the firmware.. now Arduino works fine, checked with blink sketch, if programming is impossible I can buy an UsbASP, I find one on Amazon for 7 Euros
Thank you

From previously linked website:

Uno or Duemilanove | MOSI: 11 or ICSP-4 | MISO: 12 or ICSP-1 | SCK: 13 or ICSP-3 |

Reset goes to pin 10 (mentioned on website and in sketch)

So flash ArduinoISP sketch and fix your wiring.

Then execute avrdude:

avrdude.exe -patmega32 -cstk500v1 -P[COM port] -Uflash:w:cheali-charger-[VERSION].hex:a

replace [COM port] with your arduino com port and [VERSION] with version of FW you are flashing...

You should see progress of flashing.

Ok, for now thank you very much,
After dinner I try with the configuration that you mentioned and I'll let you know.

Okay! It works! Now I can charge my 4,35V cells!
Thank you, have a great Sunday ! :)

Enjoy new FW features and don't forget to calibrate your charger. :)

Hi all,

I'm trying to do exactly the same thing, flash my Imax B6 with Cheali custom FW.

Got an Arduino Mega 2650 and think I have ISP setup correctly.

The command line is not quite working for me and I'm not sure where to edit or get the config file "-c stk500v1"?

Am I missing something?

I'm on Windows using avrdude.exe but just cannot get the custom FW HEX file written to my Imax B6 AC :-(

Any help is much appreciated!

Thanks so much!

what file?

-c stk500v1

is a parameter to avrdude.

Please post whole command and its output.

Hey Diggit, I'm blown away by your swift response, hope is returning I might be able to charge my HV Lipos and get some airtime with my new TinyWhoop today :-)

So what I'm typing in my cmd is:

avrdude.exe -p atmega32 -c stk500v1 -P com3 -U flash:w:cheali-charger-imaxB6-original_2.00-e10.3.12-20160613_atmega32.hex:a

It thinks about it for a short while, my Arduino flashes RX/TX and then I get this back:

avrdude.exe: stk500_getsync(): not in sync: resp=0xe0

avrdude.exe done.  Thank you.

By the way, I have hooked up the wires from my Arduino to my Imax using VCC, RESET and GND on the Power pins and MISO,MOSI and SCK to the Mega's SPI as per this link.

https://www.arduino.cc/en/Tutorial/ArduinoISP#toc3

Just realized the example is showing an Uno. Might this be the issue? Thought the SPI setup is the same with Uno & Mega.

Appreciate your help!

[diggit]

Ok, avrude can't recognize your programmer (arduino).

Problem is different default baud-rate, specifying it should be enough.

avrdude.exe -p atmega32 -c stk500v1 -P com3 -b 19200 -U flash:w:[your_file].hex:a

I suggest using most recent version from here. There are some fixes.

Hi Again,

thanks a lot, unfortunately I seem to have some kind of mismatch. What I get now is:

Sorry, I'm completely new to this. I will try some other firmware files...

One more thing, last post was using the -F parameter because I got this initially:

avrdude.exe: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.04s

avrdude.exe: Device signature = 0x000000

avrdude.exe: Yikes!  Invalid device signature.

             Double check connections and try again, or use -F to override

             this check.

avrdude.exe done.  Thank you.

Any idea where to look now? I feel I'm so close (but yet so far) :-)

Thanks!

I've changed the wiring and some different HEX files from unstable as well.

At least it is now reading the device and saying it's wrong.

I'm not sure if I'm actually talking to the Imax B6 (ATMEGA32) through my Arduino?

The Imax B6 does Beep and reboot when I send the command though.

Anything else?

Thanks again!

Now it seems, like wiring is wrong.

Correct signature is mandatory.

Which pin on arduino do you use as reset?

I am trying same scenario with my abused Arduino mega. My pin 10 is probably dead so i had to change next line in arduino ISP sketch and then flash new version.

#define RESET     10 // Use pin 10 to reset the target rather than SS
//to
#define RESET     3 // Use pin 3

My wring went from ICSP connector (pinout here), except mentioned RESET line moved to pin 3. Maybe try swapping MOSI and MISO lines, I am not sure from which perspective are those pin names (in image).
