系统调试

[English]

Armino平台BK7256系统调试命令

  • BK7256 CPU0的log通过串口uart1输出(默认波特率为115200)

  • BK7256 CPU1的log通过mailbox转发到CPU0串口uart1输出(默认波特率为115200)

  • CPU1 log带cpu1标签(异常log除外)

  • 由于内存缓冲区的限制,每条log数据的字节数,要小于128字节。超过这个大小的log都会被shell 模块丢弃,并输出一条 !!some LOGs discarded!! 如果log数量太多,来不及输出导致log堆积,缓冲区用完,也会输出这条提示字符串。

  • 通过串口输入log命令查看当前log配置

  • 通过串口输入log 1 3 1命令设置log为同步机制

  • log 1 3 1 命令第一个参数为echo开关 (0/1),第二个参数为log级别(0~6),第三个参数为同步开关(0异步,1同步)

  • 通过串口输入help命令查看当前支持的调试命令:

#
#log 1 3 1
log: echo 1, level 3, sync 1.

#
#help

  • 可以通过cpu1 help的命令格式,输入cpu1的调试命令:

    #cpu1 version
    
    #cpu1:get_version
    cpu1:firmware version : Apr 14 2022 23:49:08
    #
    

Armino平台BK7256系统jtag调试

  • 需要安装ANDES/AndeSight STD_V5.1.1软件

  • 需要jtag连接线

  • 默认jtag连接cpu0,BK7256有两个Jtag口(grou1/group2)

  • 可以通过setjtagmode cpu0 group1命令设置jtag连接cpu0

  • 可以通过setjtagmode cpu1 group1设置jtag连接cpu1

  • 可以通过jtagmode命令查看当前jtag状态

Unhandled Trap : mcause = 0x5, mepc = 0xcc160

比较关键的几个点:

  1. MEPC寄存器:0xcc160

  2. RA寄存器:0xcc160

  3. SP当前栈寄存器:0x3002573c

  4. 没有现场的情况下可以根据对应版本的elf文件初步分析:

~/Version$ /opt/risc-v/nds32le-elf-mculib-v5/bin/riscv32-elf-addr2line -e *.elf -piaf cc160
0x000cc160: rwm_upload_data at /home/jenkins/workspace/ArminoMainCI/properties/modules/rwnx_intf/rw_msdu.c:1299
  • 根据SP指针0x3002573c,得知当前Task为core_thread:

core_thread        [0x30025120 ~ 0x30025920]   0x300257bc   2048   0          cc164 cc160 cc124 ff68 1880 cf326 ae0f4 ce124 ce464
  • 这里面的列出来的cc164 cc160 cc124 ff68 1880 cf326 ae0f4 ce124 ce464是任务栈里可能的函数指针:
