### Basic setup summary
91-
After basic setup you will get cheapest modern digital FPV system, but you`ll not see OSD, to setup OSD you need to read [advanced setup article](/use-cases/fpv/advanced-setup/). If you want to read instruction from manufacturer, please read [this](https://store-m8o52p.mybigcommerce.com/product_images/img_runcam_wifilink/runcam-wifilink-manual-en.pdf).

130-
6. Solder the FTDI outputs to the UART pins.
131-
132-
7. Open **Device Manager**, insert the USB FTDI, and see which port it is (e.g., **COM3** or another).
133-
134-
8. After you know the **COM port**, open the Windows console and enter:
135-
```bash
136-

16. **IP address example**:
161-
- If your router is in the `192.168.0.1` subnet:
162-
- Set the first device IP to `192.168.0.123`
163-
- Set your computer IP to `192.168.0.40`
164-
(this is just an example)

### Steps to flash the firmware
24+
25+
1. Open **CMD** or the **Windows Console**, enter the command:
26+
27+
```bash
28+
ipconfig
29+

darkSrc="/src/assets/images/runcamv1ip.png"
34+
alt="ipconfig output"
35+
/>
36+
37+
Locate your **IPv4 address**.
38+
39+
2. Start **Tftpd64**:
40+
41+
<ThemeImage
42+
lightSrc="/src/assets/images/tftpd.png"
43+
darkSrc="/src/assets/images/tftpd.png"

46+
47+
[Instruction page link](https://openipc.org/cameras/vendors/sigmastar/socs/ssc338q?locale=en)
48+
49+
3. Generate a **MAC address**, and enter your IPv4 as the **TFTP server** address.
50+
51+
4. Click **Generate Instructions**.
52+
53+
5. Check your FTDI wiring:
54+
55+
<ThemeImage
56+
lightSrc="/src/assets/images/ftdi.png"
57+
darkSrc="/src/assets/images/ftdi.png"
58+

59+
/>
60+
61+
- **RX** → **TX**
62+
- **TX** → **RX**
63+
- **GND** → **GND**
64+
65+
:::danger
66+
Double-check the UART wiring before powering the board. Incorrect connections may damage components.
67+
:::
68+
69+
:::tip
70+
Identify the appropriate UART interface as specified in the hardware documentation.
71+
:::
72+
73+
6. Solder the FTDI outputs to the UART pads.
74+
75+
7. Open **Device Manager**, insert the USB FTDI, and find its **COM port**.
76+
77+
8. Open Putty with the correct port:
78+
79+
```bash
80+
putty.exe -serial COM3 -sercfg 115200,8,n,1,N
81+
```
82+
83+
9. The **Putty** window will open.
84+
85+
10. Connect power to both the **FTDI USB** and **Runcam v1**.
86+
87+
:::tip
88+
Always open Putty **before** powering the device to capture the boot log.
89+
:::
90+
91+
11. If everything is connected correctly, boot logs will appear in the Putty terminal.

12. Go to: [https://openipc.org/cameras/vendors/sigmastar/socs/ssc338q](https://openipc.org/cameras/vendors/sigmastar/socs/ssc338q)
102+
103+
13. Place the downloaded firmware `.bin` into the TFTP folder:
104+
105+
<ThemeImage
106+
lightSrc="/src/assets/images/runcamv1tftp1.png"
107+

108+
alt="TFTP firmware file"
109+
/>
110+
111+
<br />
112+
113+
14. Follow the instructions **line by line** (don’t paste multiple lines at once):
114+
115+
<ThemeImage
116+
lightSrc="/src/assets/images/runcamv1firmware.png"
117+
darkSrc="/src/assets/images/runcamv1firmware.png"
118+
alt="Firmware flashing command"
119+
/>
120+
121+
<br />
122+
123+
15. **If your download fails after the third command**, check the TFTP server settings.
124+
125+
:::tip
126+
Make sure no firewall or antivirus is blocking TFTP server communication.
127+
:::
128+
129+
16. **Example IP setup (if your router is on 192.168.0.1):**
130+
- Device IP: `192.168.0.123`
131+
- PC IP: `192.168.0.40`
132+
133+
17. Once UART bootloader works, you can flash **Wifilink firmware** via the [Multiconfigurator](https://github.com/OpenIPC/openipc-configurator/releases/)
