Blinking screen on android


(Vladimir) #1

Good afternoon.

Board BPI-M2 Ultra. Using the utility PhoenixSuite recorded on the eMMC image of Android (BPI-M2U_M2B_Android_HDMI_V1). After turning on the image on the monitor flashes at a frequency of 1.5 - 2 seconds. Connecting to the monitor on HDMI.

How to solve this problem? (Linux with CD-card works fine)

Hello, Did you mean when you were using sd card, HDMI is fine? but when you were using emmc, HDMi will be flash ?

What is the brand of your Display, maybe I could do a test.

Hello. If I start with an SD-card Linux, then the monitor is working fine. If I start Android, the monitor flashes. Android starts with EMMC, I could not write to SD-Card (Foenix Card gives an error). Monitor BENQ BL2420-T. If you connect to a TV, the image is excellent.

Good afternoon. The Android works with EMMC, there is no SD card. Phoenix Card taken on the site could not record any of the 5 cards. Tried volumes from 8 to 64 GB. Card reader built-in and external. Run the Android was possible by recording the image in the EMMC with the help of the program Phoenix Suite, taken on the same site. Website address: http://www.hotmcu.com/wiki/PhoenixCard
