[vandana]

Hi ,  I am using i.MX93 in my application i want to switch screen in every 3 minutes. I have created 3 screen and used timer API lv_timer_create(switch_screen_timer_cb, 60000, NULL) in pthread but when I used only one label in screen it is working fine ,but once i increased the widgets in on screens i am getting segmentation fault, below is error message i am getting when simulate the project.

Which version of BSP are you using?

Could you tell me the steps of reproducing this issue? So, I could try it on my side.

Hi ,

       Sorry for very late response, I am using  6.1.1 version. first you need to create 2 thread thread A & thread B. where I am using thread A to receive data from ZMQ dealer. by thread B used for display data on screen and switch between screens. for switching between screen I am using timer and in timer i load next screen. once I reach timer handler it working fine but after 4 - 5 switching I got segmentation fault.

Seems after 4-5 switching, the memory is not enough. You may check if the allocated memory is not used and then need to 'free' the memory.
