Sounds like the STM32 is not booting.
See this answer I just wrote on another thread, it explains the situation and solutions: viewtopic.php?p=20643#p20643

Hi,
I followed steps here viewtopic.php?p=20643#p20643 but it still the same problem, I can't see Crazyflie in a state where M2 and M3 are blinking.
Help please!

If you follow the procedure:
What state of the LED are you seeing?If the radio chip firmware also has a problem, you can:
- disconnect the battery
- press the button
- connect the battery
- When M2 starts blinking, release the button

Hi,
I can see all the leds blinking but I couldn't put it in bootloader mode.
Help! Thanks!

Re: blocking of the crazyflie-led M2 blue
If both M2 and M3 blue led are blinking, you are in booloader mode.
You can now upload new firmware using the Crazyradio using either the client (https://www.bitcraze.io/documentation/r ... re-upgrade) or by using "make cload" in the firmware projects.

If only M2 is flashing (a bit faster) you were probably pressing the power button too long.
Hold the power pressed for around 2 seconds.

Hi Kristoffer,
I'm trying to help Hada debug her CFs. We managed to flash the firmware using the dfu-utils, and I recompiled the firmware with the CLOAD=0 flag to flash it altogether. The behavior is still the same: when holding power to get into bootloader mode, we only have M2 blinking. I made a short video to show the behavior,it may be easier for you to help us: https://youtu.be/N4g1u1yzR0U.
Thanks for you help.

Hi!
The fact that you are using the DFU utils, might have overwritten the bootloader of the STM. We don't recommend using the DFU utils and only recommend using crazyradio PA with make Cload or the cfclient uploader.
FIRST: Try to put the crazyflie in recovery bootloader mode. Arnaud already explained the procedure before, however since I don't see it in your video I've made a video of the entire thing: https://youtu.be/is5Hy9GlWAo. You might need two people for this if this, its a bit difficult to connect the battery with one hand.
If this works, flash the latest release firmware through the cfclient: https://www.bitcraze.io/documentation/r ... re-upgrade
ONLY IF the M1 and M2 are not flashing as they are doing in my video, then probably the bootloader is broken. Try to flash it back again with this:
First get the bootloader bin here: https://github.com/bitcraze/crazyflie2- ... r/releases
After that don't try to use DFU-utils again since it can happen to easily that the bootloader is overwritten.
