Config not corrected

Hi all,
I’m using IMXRT1050-EVKB. But I feel that the settings are incorrect. When I build it, the following warning appears.If you know the cause, please let me know.
ーーー
Configuration error: Bootloader not supported on this target. ROM start not found in targets.json.

Due to the above reasons, AnalogIn seems to be not working well.ADC was not set or converted。
