Hello, I made a cf2.1hardware myself, I downloaded the firmware, but this platform is still 2.0 ，so something is wrong .I hope to get help, how to use this firmware for my cf2.1. thanks!

Hi,

To make the firmware compatible with multiple platform, tags have been added at the end of the flash so that a single firmware build can find out on what platform it is running.
For the nRF you should rebuild and reflash the crazyflie2-nrf-mbs with: For the STM, I do not think we added the tag binary file to any of the public projects, I am looking at it and will update this thread. In the mean time you can force a Crazyflie 2.1 by adding into your config.mk.
