IAR FOR AVR编译时候出现错误
错误提示如下：
Error[e16]: Segment CSTACK (size: 0x20 align: 0) is too long for segment definition. At least 0x2 more bytes needed. The problem occurred while processing the segment placement command "-Z(DATA)CSTACK+_..X_CSTACK_SIZE=_..X_SRAM_TBASE:+_..X_SRAM_TSIZE", where at the moment of placement the available memory ranges were "DATA:e2-ff"
Reserved ranges relevant to this placement:
DATA:60-e1 TINY_Z
DATA:e2-ff CSTACK
网上找了下，说是数据堆栈太小，于是呼找到这个地方

将data stack 改为0x80 尝试后不行，改为0x10却能正常编译。。。。。。datastack 这里到底需要多大？另外map文件里 用到的data stack也不多嘛，
怎么会报这个错误。。。。。。各位莫友麻烦指导下。。。
