Is there a debug application for kinetis KV series using OpenSDAv2?

[mvrlee]

During experiment stage, we have been using TWR-KV46F150M on which the MK20DX128VFM5 is already preprogrammed with OpenSDA (v1) bootloaderand and after putting a board-specific (TWR-KV46F150M) JLink debug firmware, we are able to program the KV46 MCU of board using usb.

We then bought a brand new MK20DX128VFM5 and KV46F256VLL16  to try to make a new board. However, the MK20DX128VFM5 does not have OpenSDAv1 bootloader installed since it is owned by PEmicro with no open source, we are unable to program OpenSDAv1 bootloader onto MK20.

Therefore, we flashed OpenSDAv2 onto the MK20 using JTAG, and the bootloader drive can be enumerated successfully. From there, we tried putting various debug firmwares into the bootloader to try to program the KV46 mcu through usb, but none of them worked. We tried putting JLink generic firmware for OpenSDAv2, TWR-K65F180M JLink firmware (since it also uses OpenSDAv2 bootloader), but we still cannot program the KV46 mcu no matter through JLink commander or from IAR / Keil directly. (communication error)

We therefore wonder if there is a debug firmware for KV46 using OpenSDAv2. Thanks.

P.S. I noticed that most debug firmware are board-specific, how did JLink genric firmware for OpenSDAv2 works then?
