【已解决】linux 3.4.2SDK 打开设备后无论是在中控还是手机涂鸦APP上控制设备死机

[luoji]

静态库是不会进行strip的

[luoji]

可以试下用addr2line找下0x44e2e308对应的函数名

[liuzx]

addr2line也查找不出，有没有什么其他方法。

[liuzx]

是否需要我们这边寄个机器给你们跑源码，这样感觉快一点

[lightthgil]

死机的时候，gdb输入bt打印一下堆栈。
此外，死机的程序，是直接跑的demo，还是基于SDK开发的应用

[liuzx]

死机是直接跑你们的demo,不是自己开发的应用；我试着打印堆栈看一下

[liuzx]

这个是死机时用bt参数打印的信息：

从GDB运行情况来看确实是死在SDK里面的，是否这边寄机器过来方便你们调试？？

[pushu]

这个问题还在吗？有没有环境，把我加到你的APP的家庭下，操作下

[liuzx]

在涂鸦tuya_home_control_sync.c里面的tuya_home_control_dev_room_sync_event函数打开设备（如下面代码），跑demo就会死。图片是代码修改的地方和死机的的gdb打印。
OPERATE_RET tuya_home_control_dev_room_sync_event(TY_INFO_SYNC_TP_E* sync_type)
{
TUYA_CHECK_NULL_RETURN(sync_type, OPRT_INVALID_PARM);

Code: Select all

if ((*sync_type != TY_SYNC_TP_ROOM) && (*sync_type != TY_SYNC_TP_DEV)) {
    return OPRT_OK;
}

TUYA_DEV_BRIEF_INFO_S* dev_list;
UINT_T dev_count = 0;
OPERATE_RET result = tuya_get_dev_brief_info_list(&dev_list, &dev_count);
if (OPRT_OK != result) {
    PR_ERR("tuya_get_dev_brief_info_list failed %d", result);
    return OPRT_COM_ERROR;
}

test_devices_dp(dev_list, dev_count);

TY_HOME_CTRL_DEV_CB cb;
TY_HOME_CTRL_DEV_T des = NULL;
for(UINT_T level1 = 0; level1 < dev_count; ++level1)
{
	des = tuya_home_ctrl_dev_open(dev_list[level1].id, &cb);
	printf("--%d-- --%s-- 打开设备：%s des:%d name:%s\n", __LINE__, __FILE__, dev_list[level1].id, (int)des,dev_list[level1].name);
}
tuya_dev_brief_info_list_free(dev_list, dev_count);

return OPRT_OK;

}
