esp-idfv4.4.2 Coredump报错的原因？

esp-idf 版本 : v4.4.2
示例：bluetooth/esp_ble_mesh/aligenie_demo

idf.py menuconfig 关于Coredump配置如下                                                                                                                                                                                             
配置好后执行烧录 idf.py -p /dev/ttyUSB0 erase_flash flash monitor
烧录成功执行 espcoredump.py -p /dev/ttyUSB0 dbg_corefile build/aligenie_demo.elf
报错如下：Code: Select all
