Hi All, I am designing a motor controller using the KV46F256, based on the demo board HVP-KV46
https://www.nxp.com/docs/en/user-guide/HVPKV46F150MUG.pdf 

This board use the K20 as serial and debug adapter (OpenSDAv1).

Now after soldering all components on PCB, I don't know how to flash the blanking K20 to have OpenSDAv1 from P&E Micro. I have a Serger J-Link, but always failed when try to flash. Error message is: Could not find CFI compliant flash device.

Could someone please help me on the flashing process and binary file for:

- Flashing the booloader to have OpenSDAv1 on the K20

- Flashing an app on the K20 so that I can communicate with the Kinetis K46F256.

Thank you very much!

Robert Tran
