# NXP BSP 说明
# NXP BSP 支持说明

存放RT-Thread NXP BSP目录，目前支持MCX系列，之前一些老的IC支持(如LPC/Kinetis/I.MXRT)会逐步放到此目录下
NXP 系列 BSP 目前支持情况如下表所示：

另外,我们还提供了一些热门开发板的上手说明:

* [NXP FRDM-MCXN947上手指南](https://www.rt-thread.org/document/site/#/rt-thread-version/rt-thread-standard/tutorial/quick-start/frdm_mcxn947/quick-start)
* [NXP FRDM-MCXA156上手指南](https://www.rt-thread.org/document/site/#/rt-thread-version/rt-thread-standard/tutorial/quick-start/frdm_mcxa156/quick-start)

## 注意事项

- MCX 系列是 NXP 最新推出的 MCU 系列，具有高性能和低功耗特性
- 部分老旧系列（LPC/Kinetis/i.MX RT）正在逐步迁移和更新中
- 建议优先选择 MCX 系列进行新项目开发
- 各系列 BSP 的具体支持功能请参考对应目录下的 README 文档
