77
78
79 Dragino Bootloader is a customizer made bootloader which support below features:
80
81 * OTA Update via LoRa
82 * OTA Batch update configure via LoRa
83
84 All Dragino End Devices base on LoRa ST v4 supports Dragino Bootloader.
85
86
87 === 3.1.2 How can i know if my device already have bootloader? ===
88
89 If a device has a bootloader. it will output bootloader info to UART when boot. As below:

92
93
94 === 3.1.3 How to upload bootloader to device? ===
95
96 If your is LoRa ST v4 base hardware and doesn't have bootloader. You can upload a bootloader to it.

101 **Update a firmware via TremoProgrammer:**
102
103 LoRaSTv4 Base hardware support UART update firmware. the UART connection is the same as AT Command connection, with the need for two extra action. See below for the steps:
104
105 (% style="color:blue" %)**Step1**(%%): Set BOOT Switch to (% style="color:blue" %)**PROG**(%%) mode. PROG mode is for update firmware specially.
106
107 (% style="color:blue" %)**Step2**(%%): Press (% style="color:blue" %)**Reset**(%%) button, the module will then boot into program mode.
108
109 (% style="color:blue" %)**Step3**(%%): Use (% style="color:blue" %)**TremoProgrammer**(%%) to update the firmware to LoRaST v4.
110
111 (% style="color:blue" %)**Step4**(%%): Set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) position. Press Reset button again and module will run the new software.
112
113
114 Below is the method for how to update via (% style="color:blue" %)**TremoProgrammer:**
115
116 1.  **TremoProgrammer** download link:  [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]]
117
118 2.  Run** (% style="color:blue" %)TremoProgrammer.(%%)**
119
120 3.  Choose software and set the address to (% style="color:blue" %)**0x08000000**(%%).
121
122 4. Rember to set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) after update finish. And you should be about to see Bootloader info in output after update

129
130 === 3.2.1 Update a firmware via Dragino Sensor Manager Utility.exe ===
131
132 ~1. Download **[[OTA Tool>>https://www.dropbox.com/sh/bqepfzvusv6ig8e/AACKB4J9pdY1I7s5kcKfCUGHa?dl=0]]**
133
134 2. Use below schedule to update:

144
145 == 4.1 How to recover if upgrade wrong file to bootloader? ==
146
147 You can just upload the bootloader again.
148
149
150 == 4.2 How to recover if upgrade wrong firmware via Dragino Sensor Manager Utility.exe? ==
151
152 The UART upgrade via Dragino Sensor Manager Utility.exe is base on Dragino Bootloader. So if you are able to upgrade some file via this tool. It means the device has bootloder.
153
154
155 The upgrade via Dragino Sensor Manager Utility is base on firmware level and won't effect the bootloader. If you upgrade a wrong firmware file, you can try below:
156
157 ~1. UART upgrade via Dragino Sensor Manager Utility again to the correct version. The password should use the AT PIN for the wrong firmware.  (This method is not 100% work, depends which wrong firmware you have upgraded)
158
159 2. Use **TremoProgrammer **to update firmware. [[Insturction>>||anchor="H4.3HowtouseTremoProgrammertoupdatefirmwareifthereisbootloaderinthedevice3F"]]
160
161 3. Use **[[OTA update>>http://wiki.dragino.com/xwiki/bin/view/Main/Firmware%20OTA%20Update%20for%20Sensors/]]**, this is base on Bootloader so it will work. Make you choose the correct frequency band (base on the firmware version in the sensor or use EU868 which is the default setting.)
162
163
164 == 4.3 How to use TremoProgrammer to update firmware if there is bootloader in the device? ==
165
166 Make sure your device already bootloader while use this update. Otherwise device won't be able to boot ( can be solve by upload a bootloader to the device).
167
168 LoRaSTv4 Base hardware support UART update firmware. the UART connection is the same as AT Command connection, with the need for two extra action. See below for the steps:
169
170 **Step1**: Set BOOT Switch to **PROG** mode. PROG mode is for update firmware specially.
171
172 **Step2**: Press **Reset** button, the module will then boot into program mode.
173
174 **Step3**: Use **TremoProgrammer** to update the firmware to LoRaST v4.
175
176 **Step4**: Set BOOT Switch to **FLASH** position. Press Reset button again and module will run the new software.
177
178 Below is the method for how to update via **TremoProgrammer:**
179
180 1.  Software download link:  [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]]
181
182 2.  Run** TremoProgrammer.**
183
184 3.  Choose software and set the address to **0x0800D000**. (% class="mark" %)VERY IMPORTANT for this address(%%).
185
186 4. Rember to set BOOT Switch to **FLASH** after update
