Vllink Basic2 high-speed wireless debugger unboxing and first-time use tutorial
introduction:
First of all, I would like to thank EEWorld and le062 for sponsoring the Vllink Basic2 high-speed wireless debugger. This debugger provides great convenience for embedded developers with its high-speed wireless debugging features and superior technical performance.
Unboxing experience:
It was sent like this:
Unpack the package, the package includes:
- A pair of Vllink Basic2 debuggers
- Two high-quality Type-C data cables
- Dupont wires
- A detailed instruction manual
-
It is particularly worth mentioning that the Type-C data cable uses an aluminum alloy interface and braided wire, which not only has an excellent texture, but also can activate Xiaomi's 27W fast charging, which is particularly prominent among similar products.
Let's take a look at the debugger again:
By the way, take a look at the main control scheme and workmanship:
The main control uses AIC8800M from Aicmicro, which is a dual-core M4 MCU that supports WIFI6. Those with the suffix AIC8800D are used as network cards.
Basic parameters:
- Process technology: 28 nm
- Package specification: QFN48 (5x5mm)
- RAM capacity: 992 KB (4M PSRAM)
- Flash capacity: 2 MB
Characteristic Parameters:
- 240MHz Cortex-M4 Dual Core
- 480MHz DSP
- 2.4G/5G Wi-Fi6
- BT 5.0 EDR/BLE Bluetooth dual mode
- USB HS 2.0 OTG PHY
- 1x 60MHz SPI, 1x I2C, 3x UART, SDIO, I2S
Since the main control solution used has good performance, we are very confident in its performance, and then compare and evaluate it with other debuggers.
First time use:
Before using Vllink Basic2 for the first time, I read the instruction manual carefully and understood the basic features and operation procedures of the debugger.
Hardware Hookup
- Connect Vllink Basic2 to the computer via USB cable.
- The light on the debugger turns on, indicating a successful connection.
There are a few points to note:
- AP is the transmitter, which will send a wifi6 hotspot. STA is the receiver, which is used to connect to the WIFI sent by AP. Double-click the button on link to switch the mode between USB wired, AP, and STA. AP is connected to the computer, and STA is connected to the development board. Do not connect them incorrectly. It will light up when the connection is successful. It will flash when it is connected.
- You need to determine the state of Vref. If Vref is set to 0, you need to input a voltage level (3.3V), otherwise an error will be displayed. If VRef is left floating, all logic IOs will be in a high-impedance input state and communication will not be possible. The following figure shows the connection error
- If you want to debug without connecting to the Vref level, you need to set the Vref output to 3.3V to use it correctly. Use https://vllogic.com/_static/tools/web_config_basic2/ to log in, click "Connect Vllink", select DAP in the small pop-up window, click Connect, and set Vref_Voltage_mV to 3300.
- If the two lose pairing, how to pair them? Log in to the above website again, we need to save the wifi name and password of the AP, and then fill in the information that the STA wants to connect to, so that they can be paired. As shown in the figure below, fill in the Wireless_Host_SSID and Wireless_Host_Password in the AP to the corresponding positions in the figure below. Then switch back to STA mode
- In fact, at the wireless receiving end STA, the 5V port on the link inputs 3.3V as power supply, and the link can also work normally for downloading, so there is no need to wire the daplink separately.
- To restore factory settings, follow these steps:
- Use the Chrome browser to open the configuration tool link.
- Connect the debugger and click "Connect Vllink".
- Select DAP in the pop-up window and connect.
- After modifying the configuration, click "Sync Settings" to save.
Conclusion:
The Vllink Basic2 high-speed wireless debugger impressed me with its excellent performance and stable connection. I look forward to further exploring its functions in the future and sharing my experience and evaluation report in the EEWorld Embedded System section. Stay tuned for more exciting content!
