Servo Control PPM

Hello,

I'm currently working with a VESC6 device that runs on a RC-car. I would like to add servo

controls to the VESC but I am having some issues. First, when I select firmware to flash in the VESC

tool(2.0) it starts and finished the flash without any issues but after reboot the firmware is still the

same(not updated). Second, since I got the VESC without the bootloader i also bought a ST-Link v2

and I have used that to flash aswell, and it gives the same result. When I run a BLDC detection it also

fails. So there is many things that are not in order and I'm not sure if they are connected. I appreciate

any kind of help.

Specs:

   Engine: Traxxas Velineum 3150r

   VESC: VESC6

   VESC tool: 2.0

   Battery: LiPo 5000 mah

Thanks

Update: We've successfully flashed the VESC with servoout.bin 3.66. Still we're not able to control the servo.

Any progress? I am working on servo motor either and I can detect the pwm signal from the PPM pin, but I still can change the duty cycle by using Vesc_tool
