TI中文支持网大家好：
我在跑DSPLINK的READWRITE的例程是，PROC_write报错0x80008013，然后我根据这篇文章（processors.wiki.ti.com/…/Writing_DSPLink_Application_using_PROC_read_and_write_APIs）修改了CFG_OMAP3530_SHMEM.c和dsplink-omap3530-base.tci加入了两段内存。但是运行仍然报之前的错误。我的配置如下：
——内存分配————-
# Start Addr Size Description
# ——————————————-
# 0x80000000 99 MB Linux
# 0x86300000 15 MB CMEM
# 0x87200000 13 MB CODEC SERVER
我没有用CODEC SERVER，所以想从第三部分分出两块内存用。

求大神指点
先谢过！

Jun Zhao：
另外，我运行的参数如下：
./readwritegpp ./readwrite.out 2267021313 131072 10000 0
其中第二个2267021313 和 131072分别是0x87200000和0x20000转换成10进制
