这是device_link.cmd文件的内存分布，根据报错信息 #10099-D: program will not fit into available memory, or the section contains a call site that requires a trampoline that can't be generated for this section, or the section contains padded functions. run placement with alignment fails for section ".data" size 0xeaac.  Available memory ranges:。应该需要增大.data存储的空间，即SRAM，但是我在device_link.cmd文件中把length修改为0x00040000后，再次build发现文件恢复到了我修改前。请问应该如何解决呢
