== 4.1 OTA_Tool supports two upgrade methods for -LB products. ==

249

250

251

(% style="color:red" %)**Note: The premise of using OTA_Tool is that all your devices have bootloaders.**

252

253

(% style="color:red" %)**1. **(%%)Only devices with bootloader can perform OTA upgrades(OTA upgrade method).

254

255

(% 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**(%%).

256

257

* For OTA_Tool, you can choose to use the (% style="color:blue" %)**OTA upgrade method**(%%), refer to the above upgrade steps in this user manual.

268

Each device has a shipped label with OTA Password which is 16 chars. like below. If user don't find this, please send us a photo for the device with Dev EUI to [[support@dragino.com>>mailto:support@dragino.com]] . and we will search the password for you.

== 4.3 How about if i upgrade a crashed firmware via OTA update? ==

275

276

277

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.

278

279

(% style="color:red" %)**Here are notice:**

280

281

~1. OTA update frequency depend on the firmware frequency. If there is no frequency in the firmware. Bootloader will use EU868 as default frequency.

282

283

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.

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]]

In summary, as long as your LA66 has a boot loader, either LA66 V1 or LA66 V2 can use OTA_Tool.

== 4.7 Why can't LA66 burn its own working firmware after it is used for OTA upgrade of -LB products? ==

342

343

344

We are sorry for the inadequacy of LA66 for OTA updates in the past.

345

* 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**(%%).

347

348

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.

349

350

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.

* 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.
