Hi @corndog,
I only have experience flashing BlHeli ESCs with BlHeli Suite with an Arduino Uno, but it should be quite similar with the Afro programmer.
A couple things to check:
- Does your ESC have an SiLabs or Atmel microcontroller? Its probably SiLabs. The Afro programmer may only be Atmel compatible.
- Make sure you select the proper interface and microcontroller type in the interface drop down.
- Have you selected the correct COM port on the setup tab?
- You should not have a motor attached to the ESC during programming for safety. Unexpected movements may occur.
