请教iap串口升级问题,iap启动lvgl工程只有7帧,正常是14帧？
我的一个lvgl工程从0x8000000启动,lvgl可以跑14帧,但我把lvgl工程写到0x800A000,用iap从0x800A000启动只有7帧?intmain(void){system_clock_config();at32_board_init();key_config();if(gpio_input_data_bit_read(GPIOD,GPIO_PINS_12)==0&&gpio_input_data_bit_read(GPIOD,GPIO_PINS_13)==0){flash_upgrade_flag(FALSE);}if(flash_upgrade_flag_read()==TRUE){/*checkappstartingaddresswhether0x08xxxxxx*/if(((*(uint32_t*)(APP_START_ADDR+4))&0xFF000000)==0x08000000)app_load(APP_START_ADDR);//APP_START_ADDR＝0x0800A000}while(1)}；}以上是iap启动简化代码intmain(void){nvic_vector_table_set(NVIC_VECTTAB_FLASH,0xA000);//0x0800A000nvic_priority_group_config(NVIC_PRIORITY_GROUP_4);MainStatemain_state=MAIN_STATE_INIT_ML307;crm_clocks_freq_typeget_rcc_clock;MqttSetDatadata;volatileuint32_tlast_mqtt_inti_time=0;volatileuint32_tlast_mqtt_pub_time=0;volatileuint32_tlast_signal_check_time=0;intret=0;inti=0;intdir=0;charbuffer[128];uint32_tcnt=0;system_clock_config();delay_init();uart_print_init(115200);tmr7_int_init(239,999);usart2_config();gn03s_init();lcd_struct=&lcd_dev_struct;lcd_struct->lcd_init();tp_dev.init();lv_init();lv_port_disp_init();lv_port_indev_init();setup_ui(&guider_ui);events_init(&guider_ui);ml307r_init();ml307r_on();pwm_tmr3_init();adc_dma_init();SystemParamInit();key_config();//初始化上下文mqtt_init_param(&mqtt_param);ml307_init_context(&ml307_ctx);mqtt_init_context(&mqtt_ctx,&ml307_ctx);http_init_context(&http_ctx,&ml307_ctx);while(1){tp_dev.scan(0);lv_task_handler();home_ui(&mqtt_ctx,key_ret);setups_ui(&mqtt_ctx,key_ret);}}以上是lvgl简化代码
