在vivado 2015.4中创建microblaze软核，local memory为8KB，export到SDK后，hello_world模板中加入“xil_printf("hello world\n")”后报错，错误如下：
‘.stack‘ will not fit in region ‘microblaze_0_local_memory_ilmb_bram_if_cntlr_microblaxe_0_local_memory_dlmb_bram_if_cntlr‘
region ‘microblaze_0_local_memory_ilmb_bram_if_cntlr_microblaxe_0_local_memory_dlmb_bram_if_cntlr‘ overflowed by 640 bytes
网上查找错误信息，xilinx社区的解决方案如下：

根据该链接中提供的方法，把local memory增大为64KB，问题解决。
