3.6、修改 app 固件配置

3.6.1、修改中断向量表的跳转基地址为 0x8020000。

#define RT_APP_PART_ADDR 0x8020000

static int ota_app_vtor_reconfig(void)
{
#define NVIC_VTOR_MASK 0x3FFFFF80
/* Set the Vector Table base location by user application firmware definition */
SCB->VTOR = RT_APP_PART_ADDR & NVIC_VTOR_MASK;

<span class="token keyword">return</span> <span class="token number">0</span><span class="token punctuation">;</span>

}
INIT_BOARD_EXPORT(ota_app_vtor_reconfig);
