1.SDK版本 2.1.0 芯片 GR551X

2.使用例程验证后台双区升级

按照GR5xx固件指南，获得最小App bootloader固件

如果要获得最小的App bootloader固件（Code size最小），需要采用后台双区升级模式，关闭App bootloader的低功耗蓝牙（BOOTLOADER_DFU_BLE_ENABLE）、UART升级功能宏（BOOTLOADER_DFU_UART_ENABLE），关闭Log打印宏（APP_LOG_ENABLE），关闭外部Flash宏（ENABLE_DFU_SPI_FLASH）。

BOOTLOADER_DFU_BLE_ENABLE 为1 正常跳转

BOOTLOADER_DFU_BLE_ENABLE 为0 跳转出错

3.其他无任何修改

#define BOOTLOADER_DFU_BLE_ENABLE 1
