K10 Micropython OSError [Errno116]
Miyabi.Suen 2025-05-14 15:33:05 526 Views5 Replies Some of my Unihiker_k10 board get error. Even the firmware is flashed again using flash_download_tool 3.9.8 . The code could run on my other k10 board
it has probem on ‘from unihiker_k10 import screen’

OSError: [Errno 116] ETIMEDOUT
OSError: [Errno 116] ETIMEDOUT means a device (e.g., I2C/SPI sensor, display, etc.) does not respond in time. It seems that the error happening at screen.init(dir=2). That line initializes the screen hardware — if the display is not responding (wrong connection, missing hardware, or power issue), you will get a timeout error like this.
Check that the screen is physically connected. Try a different USB cable/port. If you are running off a low-power USB port or poor-quality cable, the screen may not boot.
Lupin Would you post your micropython code so I can try to replicate this problem on my K10?
Yeez_B The code is shown as follows: I use another K10 board is no problem.There are5 out of 80 got problems after serveral uses.
It is just simply show a ‘hello' on screen
from unihiker_k10 import screen
import time
screen.init(dir=2)
screen.draw_text(text="Hello",line=0)
screen.show_draw()
while True:
time.sleep(0.1)
Even though I flash the micropython using flash tool, it still have this problem
