Part Number: LAUNCHXL-CC1310
Other Parts Discussed in Thread: CC1310

CC1310在调试过程中,NVS_write 和 Clock会有冲突.比如先调用NVS_write ,然后调用启动Clock,Clock不能启动.或者Clock启动了,调用NVS_write 后,Clock中止了.

您好，

您有使用什么sdk的示例吗？可以把相关程序部分贴上来。

Nick您好,

我使用的是Easylink TX的示例.

这是调用NVS_write的代码
void my_nvs_write(uint8_t * buff,uint16_t offset,uint16_t len)
{

//保证四字节对齐如果无对齐自动补齐
len = fix4(len);
NVS_write(nvsHandle, offset, buff, len, NVS_WRITE_ERASE | NVS_WRITE_VALIDATE);

}
在调用NVS_write 后,调用定时器或者调用串口打印,都不能成功,如果不调用NVS_write,调用定时器或者调用串口打印都正常.

被这个问题困扰很久了,现在项目就卡在这个问题上面,请帮忙分析下原因和解决办法,谢谢.

Hi Nick,

一周了都没有收到您的消息,请问有解决方法了吗?

您好，

不好意思由于一些原因回复晚了。这边是我们工程师的一些问题：

您这边是用的SDK是什么版本的？
你的两个失败案例的现象是什么，能具体描述一下吗？clock启动 API 是否返回失败状态？你能发布失败状态吗？
NVS_write 可能需要一些时间才能完成，这取决于你写了多少以及写是否触发了压缩。您是否在等待 NVS_write 在启动时钟之前返回？或者你在不同的线程中启动时钟？

原文如下：

1) Which version of the SDK are they using?

2) What is the symptom in your two fail cases? Does the clock start API return a fail status? Can you post the fail status?

3) NVS_write can take some time to complete, depending on how much you're writing and whether the write trigger a compaction. Are you waiting for NVS_write to return before starting the clock? Or are you starting the clock in a different thread?
