FreeRTOS+LVGL在国产MCU运行异常现象

白星

现象：板卡上电以后会出现一条蓝色线向下移动，大概10行左右程序会卡死在，我的屏幕分辨率是1920*720；
卡死位置在ARM内中断，arm_data_abort_handler，我怀疑是内存的问题，通过MCU自己打印出来提示

cpu prefetch abort, permission fault

IFAR 0xff0000e0 (fault address)

IFSR 0xd (fault status register)

halting

current_thread 3003C010, name TaskA


请问大佬们这个解决思路是啥，如何配置内存呢？内部RAM8M，外部SDRAM64M我全部用作堆空间了。lv_conf.h 有关内存这里我附在下面

1. /*=========================
   
2.    MEMORY SETTINGS
   
3. *=========================*/
   
4. 
   
5. /*1: use custom malloc/free, 0: use the built-in `lv_mem_alloc()` and `lv_mem_free()`*/
   
6. #define LV_MEM_CUSTOM 0
   
7. #if LV_MEM_CUSTOM == 0
   
8.     /*Size of the memory available for `lv_mem_alloc()` in bytes (>= 2kB)*/
   
9.     #define LV_MEM_SIZE (2048U * 1024U)          /*[bytes]*/
   
10. 
    
11.     /*Set an address for the memory pool instead of allocating it as a normal array. Can be in external SRAM too.*/
    
12.     #define LV_MEM_ADR 0     /*0: unused*/
    
13.     /*Instead of an address give a memory allocator that will be called to get a memory pool for LVGL. E.g. my_malloc*/
    
14.     #if LV_MEM_ADR == 0
    
15.         //#define LV_MEM_POOL_INCLUDE your_alloc_library  /* Uncomment if using an external allocator*/
    
16.         //#define LV_MEM_POOL_ALLOC   your_alloc          /* Uncomment if using an external allocator*/
    
17.     #endif
    
18. 
    
19. #else       /*LV_MEM_CUSTOM*/
    
20.     #define LV_MEM_CUSTOM_INCLUDE <stdlib.h>   /*Header for the dynamic memory function*/
    
21.     #define LV_MEM_CUSTOM_ALLOC   malloc
    
22.     #define LV_MEM_CUSTOM_FREE    free
    
23.     #define LV_MEM_CUSTOM_REALLOC realloc
    
24. #endif     /*LV_MEM_CUSTOM*/

已经解决，原因是有个地方在循环申请堆空间，大意了
