如果数组小于1K，程序正常，能收到串口发送的数据
但如果大于1K，串口收到的数据就为0
请问，这与连接文件有关系吗？链接文件如下：
OUTPUT_FORMAT("elf32-littlearm", "elf32-bigarm", "elf32-littlearm")
OUTPUT_ARCH(arm)
ENTRY(_image_start)

STACK_UND_SIZE = 0x100;
STACK_ABT_SIZE = 0x100;
STACK_IRQ_SIZE = 0x100;
STACK_FIQ_SIZE = 0x100;
STACK_SVC_SIZE = 0x400;
HEAP_SIZE = 0x00100;

MEMORY
{
    sram : org = 0x00000000, len = 128K
}

SECTIONS
{
    .text :
    {
        PROVIDE(__image_start = .);
        *(.image_header)
        PROVIDE(__text_start = .);
        *(.vectors)
        *(.text*)
        PROVIDE(__text_end = .);
    } > sram
