I need to cut off all the power supplys of VL53L8 to save power. Does the firmware need to be re-downloaded every time the device is powered on? 

loading firmware is in the function
 
uint8_t vl53lmz_init( VL53LMZ_Configuration		*p_dev)​

Yes it does. There is no firmware in the part, so at boot one has to download the code to get the part running.

One might think of this as a flaw, but it works out for ST. New parts (VL53L8CH) and variants for really large customers make the download quite attractive. I don't think there were any bug fix releases, although that's another argument for the download.

One has to admit it's kind of a hassle though.
