ty_gr551x 代码框架

首先，代码分bootloader 和App 两个部分。首先执行的是bootloader部分，然后跳转到App.

看代码：

bootloader                                                               App

1.(初始化外围信息,串口打印等)                                             1.
app_periph_init();                                                       app_periph_init();//外设初始化   
==>bootloader_wdt_init();                                                ==>pwr_mgmt_mode_set();
==>pwr_mgmt_mode_set();                                                 
                                                                                        
2.(调转App)                                                             2.
user_boot();                                                             ty_system_init();               
==>bootloader_info_get();                                                ==>ty_system_log_init();
==>is_fw_need_copy();                                                    ==>ty_flash_init();
==>is_jump_user_fw();==>jump_user_fw();    ======> Jump to App           ==>ty_uart_init();
                                                                         ==>ty_uart2_init();
                                                                         ==>ty_rtc_init();
                                                                         ==>ty_pin_init();//gpio初始化

3.                                                                      3.
