Single and dual bank DFU all failed over RedMi Note3 Phone

[Milk]

Firstly，the RedMi Note3 DFU failed used by dual bank，however Xiaomi3 Phone can DFU successfully.As the questionlink text mentioned,the process of the RedMi Notes3 Phone DFU stopped at the line APP_SCHED_QUEUE_FULL(). The details over the OTA app on RedMi3 as follows:

The red frame in the picture 3,the normal status is 1,why the status is 6?What's the meaning of the status?

Could you try increasing the SCHED_QUEUE_SIZE define in main.c to a higher value, e.g. 30

#define SCHED_QUEUE_SIZE                30

I have tried as you say,but it failed. What circumstance,it will lead the result of m_queue_start_index = m_queue_end_index?

Hi again, could you try to decrease it to 10, i.e.

#define SCHED_QUEUE_SIZE                10

and see if that helps.

Decreasing it to 10 has no effect on OTA,but I change it to 768,sometimes the rate of OTA progress can reach to 7%.

I have checked the code step by step,found the program stop at the event as follows: static void on_dfu_evt(ble_dfu_t *p_dfu,ble_dfu_evt_t *p_evt)

{ // // }

It means that there is no dfu_event to generate. The dfu_event is defined as follows: static void services_init(void)

{ uint32_t err_code; ble_dfu_init_t dfu_init_obj; memset(&dfu_init_obj,0,sizeof(dfu_init_obj));

dfu_init_obj.revision = DFU_REVISION; dfu_init_obj.evt_handler = on_dfu_evt; dfu_init_obj_error_handler = service_error_handler; ble_dfu_init(&m_dfu,&dfu_init_obj); }

What happened to the program?
