[参考译文] CC1310：Simplelink SDK 与较旧的 TI-RTOS 闪存效率对比

你(们)好、Siri

谢谢..并且完全理解您关于坚持使用最新 SDK 的建议。

为了做到这一点、我们研究了修改.cfg、但必须承认、没有取得太多进展。

虽然项目目录中没有.cfg、但我相信内核会使用该路径上的共享文件？

C：\ti\simplelink_cc13x0_sdk_4_10_02_04\kernel\tirtos\builds\CC1310_LAUNCHXL\release

假设我们仅需要 I2C、RF (现在保持多模式)、我们可以在其中禁用 SPI、UART、NVS 等

我已附上文件内容以供参考

此外、如果您可以向我们提供有关使用 TI .cfg 的应用手册、我们将不胜感激。

谢谢

你(们)好、Siri

谢谢。

但该配置文件来自 SDK 工程、而不是移植的 RTOS 工程。

如初始消息中所述、我们在最新的 SDK 驱动程序示例中开始了关断项目。因此、请充分了解不同项目的闪存使用情况。

我们试图理解的是如何按照您的建议使用此.cfg 文件来保存闪存。

我们减少了优先级、允许的任务等数量、但未对重建闪存大小进行更改。
