Dear liuzhonghui liu,
Please check the state of your device by refer: DAPLink bootloader update.
If it's in corrupted state. Then you can recover the board by updating the debug interface firmware again.
If it's in bricked state. Then you can only recover the board by flashing a new bootloader with an external debug probe.
Here the TWR-KV58F220M is not in the list of table.
Considering that the OpenSDA versions of the FRDM-K22F and TWR-KV58F220M boards are both V2.1, customer can direct use the file of FRDM-K22F.
Best Regards,
Robin
