YH601S死机信息查看

死机原因与如何查看死机离线死机日志查看方法。使用场景整机，想看看用户有没有死机过。可以在手表的/user/exc目录下看看有没有死机文件exc_info.bin死机文件解析

死机日志都会存在 /user/exc/目录下

双击env_start.bat在这里执行

执行tools/tools、dump_parser_v1.5/下的run.bat

python run.bat /user/exc/exc_info.bin

可以通过查看ssb里面的reboot重启原因,可以作为没有死机文件场景下的辅助定位手段。

查看重启日志

SSB|System Boot Abnoraml, hard fault crash

SSB|System Reboot cause:0x2004, total reboot count:1, exception reboot count:1

比如这里的cause为0x2004，那么对应的重启原因就是A核的异常导致。

对应的枚举就是REBOOT_CAUSE_APPLICATION_HARDFAULT = 0x2004

经常出现的死机都是访问了非法地址，用户可以访问的合法地址的范围如下

DTCM 起始地址 长度
#define APP_DTCM_ORIGIN 0x20000000
#define APP_DTCM_LENGTH 0x70000
L2RAM 起始地址 长度
#define L2RAM_OFFSET 0x60240000
#define L2RAM_FOR_APP_START L2RAM_OFFSET
#define L2RAM_FOR_APP_LENGTH 0x160000 /* 640K *
PSRAM 起始地址和长度
#define PSRAM_BASE_ADDR 0x6C000000
#define PSRAM_LENTH 0x1000000
