I've found a few posts on a UART bootloader for the KEA128, they're all old posts though so I'd like to know what the best approach today would be.
- What I've gathered is I could port the example UART bootloader for E series (AN4767).
- There's also KBOOT, though I don't think there's support for the KEA128.
- There's OpenSDA, but I'm not sure if that provides a UART bootloader over a COM port.
Are there other options? What's the best approach?
