	373	+=== 1.10.2 Update method: For LA66 without bootloader ===
	374	+
	375	+
	376	+* Explanation:
	377	+
	378	+For LA66 without a bootloader, we can only burn a bootloader for it in the following way. Because using OTA_Tool to upgrade the firmware of LA66 this address is (% style="color:blue" %)**0x0800D000**(%%) by default, but our bootloader needs to be burned at address .
	379	+
	380	+Therefore, you can use this method to download the firmware with the boot loader directly or upgrade your boot loader (address from (% style="color:blue" %)**0x08000000**(%%)).
