[santhosh205415]

I want to port LVGL C project into C++ project so after porting it completely, I have a problem while linking time

Any Help?

Hello Santhosh kumar, 

The LittlevGL examples that we provide within the SDK use the external SRAM instead of the internal SDRAM, this due to the large amount of RAM that these projects needs. Based on the information that you attached, I'm able to see that you are using the internal SDRAM and the problem you are facing is that the data won't fit in this region. You need to use the external SRAM instead. 

Best Regards, 

Victor
