TI中文支持网我现在开发的东西，基于SimpleBLEPeripheral工程的FlashROM模式开发，未使用OAD。
现在需要在单片机上保存部分用户数据，数量不多，也就100字节左右吧，调试SNV时发现了诡异的问题：
无论是读取还是写入数据，函数都会返回0x02，也就是INVALIDPARAMETER错误。
写入的ID使用的是0x80和0x85，均如此。
已经纠结了一天，未能确定原因，但发现osal_snv_init()函数似乎没有被执行，在这个函数入口处打不上断点，在函数内写了个死循环while(1);也不会卡住；我单独在main()函数中单独调用osal_snv_init()函数的话，编译不过，现在我重点怀疑是因为osal_snv_init()没有执行导致的，但不知道该怎么办，因为这个函数包含在osal_snv.c中，而这个文件一旦加入工程，编译就报错（读写SNV的函数重复，但屏蔽掉后还有其它错误）。
请问这个是怎么回事？SimpleBLEPeripheral工程应该是可以用SNV的吧？
/****************************************************************************/
我再补充一下我的调试流程：
刚刚测试确认osal_snv_init()函数未编译，我把末尾分号去掉人为制造出了语法错误，编译通过……
顺着函数调用处向前查，发现该函数所在的stack_main()由ICall_startup.c文件中的startup_entry()函数调用，这个函数也没有编译。
startup_entry()再向前就查不到了，出现下面一堆我看不懂的东西：
#ifdef __TI_COMPILER_VERSION__
#pragma CODE_SECTION(startup_entry,"EntrySection")
#elif defined(__IAR_SYSTEMS_ICC__)
#pragma location="EntrySection"
#endif
这一堆宏貌似是区分编译器，进行绝对地址定位，全工程搜索找不到函数调用位置。
换个思路：
不依赖上面那一堆东西，我自己调用osal_snv_init()进行初始化，挂osal_snv.h后，报函数未定义错误，工程本身似乎没有加入osal_snv.c文件。
手动添加到工程中后，osal_snv.c文件中的osal_snv_read()、osal_snv_write()与ICallBleAPI.c文件中的两个函数重复，编译不过。
屏蔽掉osal_snv.c中的osal_snv_read()和osal_snv_write()后，编译依然过不了，报Flash相关操作的函数未定义……
/****************************************************************************************************************************/
此问题已经解决，这两个函数不能在其他任务中访问，否则就会报错。谢谢各位网友的帮忙~
Alvin Chen：
你打开OSAL_SNV=2在预编译option里面，
然后包含头文件#include "osal_snv.h"。

The Simple NV (SNV) area of flash is used for storing persistent data, such as encryption keys from
bonding or to store custom defined parameters. The protocol stack can be configured to reserve up to two
4kB flash pages for SNV, although valid data is only stored in one active flash page. To minimize the
number of erase cycles on the flash, the SNV manager performs compactions on the flash sector (or
sectors) when the sector has 80% invalidated data. A compaction is the copying of valid data to a
temporary area followed by an erase of the sector where the data was previously stored. Depending on
the OSAL_SNV value as described in Table 3-2, this valid data is then either placed back in the newly
erased sector or remains in a new sector. The number of flash sectors allocated to SNV can be configured
by setting the OSAL_SNV preprocessor symbol in the stack project. Table 3-2 lists the valid values that
can be configured as well as the corresponding trade-offs.
Table 3-2. OSAL_SNV Values
OSAL_SNV Value Description
0 SNV is disabled. Storing of bonding keys in NV is not possible. Maximizes code space for the
application and/or stack project. GAP Bond Manager must be disabled. In the Stack project, set preprocessor
symbol NO_OSAL_SNV and disable GAP Bond Manager. See Section 10.4 for configuring
Bluetooth low energy protocol stack features.
1 (default) One flash sector is allocated to SNV. Bonding info is stored in NV. Flash compaction uses flash cache
RAM for intermediate storage, thus a power-loss during compaction results in SNV data loss. Also,
due to temporarily disabling the cache, a system performance degradation may occur during the
compaction. Set preprocessor symbol OSAL_SNV=1 in the Stack project.
2 Two flash sectors are allocated to SNV. Bonding information is stored in NV. SNV data is protected
against power-loss during compaction.
Other values for OSAL_SNV are invalid. Using less than the maximum value has the net effect of
allocating more code space to the application or stack project. SNV can be read from or written to using
the following APIs.
uint8 osal_snv_read( osalSnvId_t id, osalSnvLen_t len, void *pBuf)
Read data from NV.
Parameters id – valid NV item
len – length of data to read
pBuf – pointer to buffer to store data read
Returns SUCCESS: NV item read successfully
NV_OPER_FAILED: failure reading NV item
uint8 osal_snv_write( osalSnvId_t id, osalSnvLen_t len, void *pBuf)
Write data to NV
Parameters id – valid NV item
len – length of data to write
pBuf – pointer to buffer containing data to be written. All contents are updated at once.

您好，已经在Option的预定义框中加上了OSAL_SNV=2语句，依然返回0x02代码。

您好，不知您能否看懂中文，我能阅读英语但我不会说英语，请见谅。
您后面的内容好像是文档中的资料。上面程序中，您使用status变量接收返回值，我也是类似的写法，然后这个变量的值为0x02。

在APP和Stack的预编译选项中都添加了OSAL_SNV=2，还是不行，我已经怀疑人生……

这个程序中涉及SNV的部分不就是564~581这一段吗？我也是这么用的呀，依旧返回0x02，写入读取均失败，真是邪门了……

CC2640的SimpleBLEPeripheral_onchip_oad例程直接有SNV操作，你玩一下看看行不行
