Third-Party System Installation Issues
Resolve SD card, serial connection, flashing failure, and post-installation responsiveness issues on Read Pico.
Common issues
| Problem | What to do |
|---|---|
| No SD card detected | Insert a separately purchased microSD card, up to 512 GB. The card must be formatted as FAT32. |
| Serial port missing | Try another USB data cable or port, and close other webpages, flashing tools, or terminals using the port. |
| Device cannot connect | Use desktop Chrome or Edge. Mobile browsers and WeChat's in-app browser do not support these web flashing steps. If writing has not started, reconnect the device. If download mode is required, follow that system's instructions. |
| Screen is slow, frozen, or still shows the old image after installation | Confirm that flashing has finished, then briefly press the power key. If the device still does not respond, press and hold the power key, releasing it when the screen changes. |
| Installation interrupted or verification failed | Keep the device connected and retry as instructed by the flashing page. Do not unplug or force a restart before writing has finished. If the page provides an operation log, save it and send it to the system developer when reporting the issue. |
System-specific issues
Pico Reader cannot connect
On a device already running Pico Reader, use 设置 → Pico 设备卡片 → 升级 → 进入 BOOT 模式 (Settings → Pico device card → Upgrade → Enter BOOT mode) to enter download mode. Wait for the computer to detect the serial port again, then retry. For a first installation, connect the device directly using the Pico Reader installation steps.
No books in the Pico Reader bookshelf
No books are included with the system. Put EPUB or TXT files in the microSD card's books folder, then open them from the device's bookshelf.
RickyOS installation is unavailable after the check
Follow the installation page's instructions. Use 查看本次操作记录 (View this operation's log) to save the log, then visit the RickyOS website to find a feedback channel and share the log with the team.
