TF card tips​

Some TF cards are not suitable as a system drive. Follow the image page or the board’s official guidance, and prefer reliable, healthy cards from trusted sources. Low‑quality TF cards often show:

  • Fake capacity leading to failures mid‑flash
  • Slow writes stretching flash time significantly
  • Frequent read/write errors after some use

Before you flash​

Regardless of medium, beforehand you should:

  • Back up anything on the target medium (flashing wipes existing data)
  • Power off the board to avoid accidental boot during flashing
  • Keep the PC on stable power (laptop plugged in—avoid sleep during flashing)
