system crash randomly and board loses power #15

I have a HDMI touch display connected to tinker board. The issue with this image is that it randomly crashes and the board does not even reboot after that. The power LED's on the board are also off and needs power cable unplug-plug to start again. Unable to debug error.

Dear, umeshjaiswal What is the power source of the HDMI touch display ? Does it have an external power supply or it is powered by Tinker's USB port ? If powered by Tinker's USB port, may I know your AC adaptor SPEC ? We suggest 5V/3A will be better and 5V/2.5A at least.

Dear Jamess, Thank you for your prompt reply. As for your query I am using a Ac adapter with output of 5.2V 1.8A. for tinker and the display is on another adapter with 12V 1A output. So, as you suggested I will try a new power source for tinker with given specs and see if issue exists. Also I have a query regarding video playback from local storage. I tried to play a downloaded file inside webview but it gives error on logcat 'file not found'. And yes I have given the correct path. If any suggestions please reply.

I am using ionic to build my app.How did you build it? Can you show me some code snippets that may be helpful.

Hi umeshjaiswal20,

I didn't use ionic to build app. I just open browser and type "file:///sdcard/Movies/1.mp4" in address bar and test it is work.

Thank you! Jamess and alex3788 for your help. I have resolved the system crash issue using a better power source as suggested and it worked. The video playback issue was from ionic build. Since alex pointed out that videos play in browser it was easier to debug error.The error was I was requesting for file even before loading of app. Kudos! closing issue.
