73 === 3.1.1 What is Dragino Bootloader? ===
74
75
76 Dragino Bootloader is a customizer made bootloader which support below features:
77
78 * OTA Update via LoRa
79 * OTA Batch update configure via LoRa
80
81 All Dragino End Devices base on LoRa ST v4 supports Dragino Bootloader.
82
83
84 === 3.1.2 How can i know if my device already have bootloader? ===
85
86 If a device has a bootloader. it will output bootloader info to UART when boot. As below:

89
90
91 === 3.1.3 How to upload bootloader to device? ===
92
93 If your is LoRa ST v4 base hardware and doesn't have bootloader. You can upload a bootloader to it.

98 **Update a firmware via TremoProgrammer:**
99
100 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:
101
102 (% style="color:blue" %)**Step1**(%%): Set BOOT Switch to (% style="color:blue" %)**PROG**(%%) mode. PROG mode is for update firmware specially.
103
104 (% style="color:blue" %)**Step2**(%%): Press (% style="color:blue" %)**Reset**(%%) button, the module will then boot into program mode.
105
106 (% style="color:blue" %)**Step3**(%%): Use (% style="color:blue" %)**TremoProgrammer**(%%) to update the firmware to LoRaST v4.
107
108 (% style="color:blue" %)**Step4**(%%): Set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) position. Press Reset button again and module will run the new software.
109
110
111 Below is the method for how to update via (% style="color:blue" %)**TremoProgrammer:**
112
113 1.  **TremoProgrammer** download link:  [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]]
114
115 2.  Run** (% style="color:blue" %)TremoProgrammer.(%%)**
116
117 3.  Choose software and set the address to (% style="color:blue" %)**0x08000000**(%%).
118
119 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

124
125 == 3.2 Update Firmware (Assume the device already have a bootloader) ==
126
127 === 3.2.1 Update a firmware via Dragino bootloader ===
128
129
130
131
132 === 3.2.2 Update a firmware via TremoProgrammer ===
133
134 Make sure your device already bootloader while use this update. Other device won't be able to boot ( can be solve by upload a bootloader to the device).
135
136 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:
137
138 (% style="color:blue" %)**Step1**(%%): Set BOOT Switch to (% style="color:blue" %)**PROG**(%%) mode. PROG mode is for update firmware specially.
139
140 (% style="color:blue" %)**Step2**(%%): Press (% style="color:blue" %)**Reset**(%%) button, the module will then boot into program mode.
141
142 (% style="color:blue" %)**Step3**(%%): Use (% style="color:blue" %)**TremoProgrammer**(%%) to update the firmware to LoRaST v4.
143
144 (% style="color:blue" %)**Step4**(%%): Set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) position. Press Reset button again and module will run the new software.
145
146
147 Below is the method for how to update via (% style="color:blue" %)**TremoProgrammer:**
148
149 1.  Software download link:  [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]]
150
151 2.  Run** (% style="color:blue" %)TremoProgrammer.(%%)**
152
153 3.  Choose software and set the address to (% style="color:blue" %)**0x0800D000**(%%). (% style="color:red" %)VERY IMPORTANT for this address.
154
155 4. Rember to set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) after update
