375 -* Explanation:
376 376  
377 -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 .
378 378  
379 -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**(%%)).
