Description

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

What MCU/Processor/Board and compiler are you using?

NXP MIMXRT 1176

What LVGL version are you using?

8.3

What do you want to achieve?

Smoother execution in screen

What have you tried so far?

Code to reproduce

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

The code block(s) should be formatted like:

/*You code here*/

Screenshot and/or video

If possible, add screenshots and/or videos about the current state.

Does the other address belong to a different physical memory?

Thanks for the fast reply
Its same physical memory with default address location (0x30000000) and other boot location (0x30025000)

It must be something NXP specific. Probably the memory access time is different in these regions. Or one is not cache-able.

Thank you

The issue was resolved. It was a NOR flash speed issue.
