Hi,
ask questions again,(◡‿◡)
Board infomation:
----------------------------------------------------------------------------------------
CPU:zynq z7020 RTEMS version: master version
SMP define:
#define CONFIGURE_MAXIMUM_PROCESSORS 2
#if 1
#define CONFIGURE_MAXIMUM_PRIORITY 255
#define CONFIGURE_SCHEDULER_PRIORITY_SMP
The only SMP scheduler supported by libbsd is:
#define CONFIGURE_SCHEDULER_EDF_SMP
#include <rtems/scheduler.h>
RTEMS_SCHEDULER_PRIORITY_SMP(a, CONFIGURE_MAXIMUM_PRIORITY + 1);
RTEMS_SCHEDULER_PRIORITY_SMP(b, CONFIGURE_MAXIMUM_PRIORITY + 1);

#define SCHED_B rtems_build_name(' ', ' ', ' ', 'B')
#define CONFIGURE_SCHEDULER_TABLE_ENTRIES \
RTEMS_SCHEDULER_TABLE_PRIORITY_SMP(a, SCHED_A), \
RTEMS_SCHEDULER_TABLE_PRIORITY_SMP(b, SCHED_B)

I am switching from AMP mode to SMP mode, and found 2 problems.
1. top command display message, Load is 100%, and Idle is almost 100% too.
Is it right? In fact,CPU is doing nothing.
Tasks: 25 Load Average: 100.510% Load: 100.966% Idle: 99.033%
Mem: 457M free 50M used 516K stack
ID | NAME | RPRI | CPRI | TIME |
TOTAL | CURRENT
------------+---------------------+---------------+---------------------+---------+--^^----
0x09010002 | IDLE | 510 | 510 | 4m9.328460
| 50.073 | 100.000
0x09010001 | IDLE | 510 | 510 | 4m7.319959

0x0a010002 | WDOG | 6 | 6 | 0.003674
| 0.000 | 0.001
2.when I connect to RTEMS with ftp or telnet, system reset.
If just only define CONFIGURE_MAXIMUM_PROCESSORS，ftp and telnet is ok.
