14.1	130
	131

54.1	134	(% style="color:red" %)1. (%%)Only devices with bootloader can perform OTA upgrades(OTA upgrade method).
	135
	136	(% style="color:red" %)2.(%%) This is because the boot loader's address is (% style="color:blue" %)0x08000000(%%), the general functional firmware's address is (% style="color:blue" %)0x0800D000(%%), and burning the firmware through OTA_Tool will only write content to the address (% style="color:blue" %)0x0800D000(%%). So whether you use the OTA_Tool's OTA upgrade method or the UART upgrade method, you can only use it to download firmware without a bootloader, otherwise you will incorrectly place the bootloader at address (% style="color:blue" %)0x08000000(%%).

20.2	158	OTA update is done via Bootloader and only change the firmware partition. So update a crash firmware via OTA update won't destroy bootloader and user can use OTA method to update again.

20.1	161
20.2	162	~1. OTA update frequency depend on the firmware frequency. If there is no frequency in the firmware. Bootloader will use EU868 as default frequency.
20.1	163
20.2	164	2. OTA update require a reset or reactivate action. If the crash firmware doesn't have them work, user need to manuall push the physic reset button on the PCB or power off/on device.

	213
	214
	215	The most obvious hardware difference between LA66 V1 and LA66v2 when burning is the presence of a "RESET "button, and the RESET operation is only for LA66 without a boot loader, you can refer to this link to learn how to upgrade LA66 without a boot loader：[[LA66 USB LoRaWAN Adapter User Manual - DRAGINO>>url:https://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LA66%20USB%20LoRaWAN%20Adapter%20User%20Manual/#H1.10.2Updatemethod:A0ForLA66withoutbootloader]]

	218
50.1	219	In summary, as long as your LA66 has a boot loader, either LA66 V1 or LA66 V2 can use OTA_Tool.
	220
	221
	222	== 4.7 Why can't LA66 burn its own working firmware after it is used for OTA upgrade of -LB products? ==
	223
	224
	225	We are sorry for the inadequacy of LA66 for OTA updates in the past.
	226
	227	* In the past, the download address of LA66 OTA DONGLE V1.0 was (% style="color:blue" %)0x08000000(%%), and the address of the bootloader that existed by default when the LA66 was shipped was also (% style="color:blue" %)0x08000000(%%).
	228
	229	Therefore, when you burn OTA_Firmwar v1.0 (LA66 OTA DONGLE v1.0) for the LA66 in order to use the LA66‘s ability to perform OTA upgrades for -LB products, the LA66’s bootloader is overridden.
	230
	231	So if you need to switch back to the LA66's working firmware, you'll need to refer to this [[link>>https://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LA66%20USB%20LoRaWAN%20Adapter%20User%20Manual/#H1.10.2Updatemethod:A0ForLA66withoutbootloader]] for instructions to burn firmware with a bootloader for the LA66.
	232
	233	[[image:image-20250122113225-5.png\|\|height="336" width="798"]]
	234
	235	* For the new version of LA66 OTA DONGLE V1.1, we have changed the supported download address to (% style="color:blue" %)0x0800D000(%%) the same as other working firmware addresses, so you can simply use OTA_Tool to burn LA66 OTA DONGLE V1.1 and LA66 working firmware for LA66.
