;* File Name : startup_stm32f429xx.s
;* Author : MCD Application Team
;* Description : STM32F429x devices vector table for MDK-ARM toolchain.
;* This module performs:
;* - Set the initial SP
;* - Set the initial PC == Reset_Handler
;* - Set the vector table entries with the exceptions ISR address
;* - Branches to __main in the C library (which eventually
;* calls main()).
;* After Reset the CortexM4 processor is in Thread mode,
;* priority is Privileged, and the Stack is set to Main.

# TencentOS tiny Cortex V7-A支持(基于正点原子阿尔法alpha开发板)
## 如何运行
1. 安装arm交叉编译器（本构建采用6.5.0版本）
2. 在TencentOS-tiny\board\ALPHA_I.MX_emmc_256ddr目录下，根据自己的arm交叉编译器版本及安装目录，对应修改Makefile中的如下变量：
- GCC_VERSION
- GCC_DIR
3. 在TencentOS-tiny\board\ALPHA_I.MX_emmc_256ddr目录下执行make命令
4. 利用正点原子官方的imxdownload工具，将out/target/TencenOS_tiny.bin烧写到SD卡中
5. 将SD卡插入阿尔法开发板，接上串口，开发板复位上电，可从串口中看到两个任务以一定的时序交叉运行（业务入口文件为TencentOS-tiny\board\ALPHA_I.MX_emmc_256ddr\src\main.c）。
## 注意
1. 正点原子阿尔法开发板的相关板级驱动，由正点原子官方示例提供，并已提前征得正点原子官方同意将相关源码作为示例代码集成。
2. 正点原子官方烧写工具目前只支持linux平台。
3. 后续TencentOS tiny会集成自己的镜像烧写工具（原子官方的烧写工具可定制性稍有欠缺）
