LVGL screen updating issue

[akhil__]

MCU - MIMXRT 1176

LVGL  version - 8.3.5

GUI guider Version - 1.7.2

I’m using LVGL for my project(Code generated with the help of GUI guider). When I’m flashing the code to the default address location(0x30000000), it works fine. However, if I’m flashing to another boot location( 0x30025000) using the bootloader, I face issues like screen lagging (updates are slower). Is there any specific reason for this? Am I missing any settings here?

I've tried using a counter in both modes (Normal and Boot). The time required to increment the counter from 0 to 100 is the same in both modes, but the counter values reflected on the screen is lagging and are not as smooth (some values are missing) in Boot mode.

Hi @akhil__,

Is there a specific reason why you are trying to boot from 0x30025000 instead of the default boot location at 0x30000000?

BR,
Edwin.

Hi @EdwinHz 

Since we are using custom boot loader for updating firmware through OTA and CAN, so we reserved 150kb from 0x30000000  for boot project(boot code). remaining memory from 0x30025000 for application purpose.
