esp32_devkitc_v4(WROVER-B)板子不断重启（failed to load RF calibration data ）

[raymond]

烧写v4.0.1中examples\bluetooth\esp_ble_mesh\ble_mesh_node\onoff_client例子，menuconfig配已了CONFIG_BLE_MESH_ESP_WROVER，烧写完成后可以正常运行，然后经过几次断电（usb连pc供电）后，不断出现以下错误，尝试idf.py flash重烧，还是出现同样错误，使用idf.py erase再idf.py flash，也是同样错误。
目前手上三块板子有一块出现了这种问题，刚买三天。
请问如何解决，谢谢！
