Sometime restart while doin nothing, where should I start looking?

Sometimes while they just sit there loading they restart and annoyingly don't start loading again. I got this message over the console after one such restart

I am running a firmware modified for p2p communication (so the nrf code is slightly different too), though my code shouldn't really be doing anything beside waiting in that situation. I think it didn't do that some changes ago maybe after I integrated some changes from the main git for the firmware and the nrf firmware (guess I should probably roll it back and see where it started.)

Anyway I figure I will figure it out if I invest time in it, but if anybody has a type for where to start looking I would appreciate it because I expect it to be frustrating.

Btw while I am at it is there a good guide somewhere how to flash multiple at once with warmboot? Edit: ah nvm with a few changes to the reset_to_bootloader of cfloader.py flashing works. I don't know how to do it at the same time (can I with 1 antenna?) but setting up a script to flash them 1 after another is already more comfortable.

Hard to say but the console seems to have problems with I2C connection. Could be a glitch in the connection between the z-ranger and crazyflie.

Flashing FW to many, one after the other, is possible with a script. Please check the cload* scripts here.
