Single bank DFU failed over Meizu phone and 360phone

[Milk]

First,the meizu phone can dfu successfully in the dual bank mode, So do the 360 phone. But in single bank DFU,this two kinds of phone failed, So I make the programm enter the debug mode, It stopped at the file app_scheduler.c about the line 133 in the bootloader project of SDK9.0. It generated the error_code = NRF_ERROR_NO_MEM, I found the variable event_index is equal to 0xFFFF,it means that the function APP_SCHED_QUEUE_FULL() is equal to true.So I comment the function APP_SCHED_QUEUE_FULL(), then DFU retry again,at last,dfu successed.

I have a question,would commenting the APP_SCHED_QUEUE_FULL() make some other problems? The details over the OTA app on RedMi3 as follows：

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

#define SCHED_QUEUE_SIZE                30
