STM32's Std driver is indeed unstable, CubeMX driver also.

Re: how force support dwm1000 deck?

config the file crazyflie-firmware\crazyflie-firmware\tools\make\config.mk.example ?

for example:

## Load a deck driver that has no OW memory
# CFLAGS += -DDECK_FORCE=bcBuzzer

I am using the lps-node-firmware eeprom, NUMBER_OF_BYTES_READ is 30, pass. but when set as 100,

printf the following error:

Code: Select all

CONFIG	: EEPROM magic not found!
CONFIG	: Writing default EEPROM configuration
Witing the list is not supported!!
