UnitV2 Firmware Update Tutorial
Firmware Download
Click the link below to download the UnitV2 firmware package and unzip it to the root directory of the TF card. (Please place the firmware file directly into the root directory of the TF card, and do not change the file name).
Getting Started with Update
Note: All user files on the UnitV2 will be erased.
Power supply must be sufficient at 5V, and power must not be interrupted during the first power-on burn-in.
During the 4-minute wait, the LED light will briefly show a dim white light followed by both white and red lights being on simultaneously. So, if you see a dim white light, wait for about 10 seconds. If the red light doesn't come on, the burning process is completed.
After burning, let it run for more than 10 seconds before disconnecting the power.

4. After powering on for 1-2s, the red light starts flashing, and after flashing for 2s, the red light stays on. At this time, release the top button.
5. The firmware starts burning, wait for about 4 minutes, and finally the red light goes off, and the white light is dimly lit.

After the update is complete, the device indicator light will go out. At this time, keep the device connected and access the domain unitv2.py or IP:10.254.239.1 through a browser. If you can successfully access the online recognition function page (as shown below), the update is complete. Note: Before using, please install the SR9900 driver.
