373 +
374 +
375 +* Explanation:
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 +
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**(%%)).

Second, connect the LA66 USB LoRaWAN Adapter v1.2 to a USB hub or computer USB port so that it will enter burn mode. Then follow the steps below to burn the firmware.**
