1.SDK版本:3.9.0

3.烧录方式,0地址烧录QIO文件
4.模组ZTU

宏定义:ENABLE_TAL_LOG已经打开 MCU_CORE_8258已经打开
生效函数:tal_log_create_manage_and_init(TAL_LOG_LEVEL_DEBUG, 128, (CONST TAL_LOG_OUTPUT_CB)Tl_printf);

麻烦确认tal_log.h中，#define ENABLE_LOG 1

1.参考下，TuyaOS\docs\Tuya 泰凌平台zigbee开发指导.pdf 的 "2.0 打印调试" 章节介绍

默认使用虚拟串口输出，具体看下app_print_get_cfg函数配置
