cc1310 是否支持片内OAD？有何限制吗？

工程师你好：

希望能帮忙确认一个问题，看到EasyLink里的例程有rfWsnNodeIntFlashOadClient的例程，但内容又提及外部flash，所以CC1310（F128）是否支持片内OAD功能呢？

使用OAD功能是否一定要在15.4Stack下来使用呢，基于EasyLink是否可行？

谢谢！

Viki Shi：

CC1310（F128）不支持，原因如下：

There is none. It has been deciced to not support OAD on-chip on 128 KiB devices officially. Considering the following requirements, your application size will be limited to 60 KiB effectively:

4 KiB flash page required for the bootloader
4 KiB flash page required for the CCFG section (always the last bytes at the end of the flash)
120 KiB available for application + image

There might be still the option to compress the binary image and get some extra space for the application, but I wouldn't rely on that. Experience has shown that TI-RTOS applications with significant functionality + communication stacks grow easily much beyond 64 KiB.

Viki Shi：

补充：
TI 15.4Stack只能片外OAD，EasyLink可以支持片上OAD
片上OAD的约束和要求:
In order to perform On-chip OAD the application design must meet the following requirements:

The application must be built without the .ccfg section.
Image header + application image must not exceed 60 KiB code size.
The application must be built with OAD capabilities.
