ESP32C3 flash end command failed (ESF-79)

[LINGlong-zi]

Port

ESP32

Target chip

ESP32C3

Hardware Configuration

** Master board: Olimex esp32-poe board
** Target board: Seeed Xiao esp32c3 board
** Baudrate: 115200*8
** Connection:
UART input and output are set correctly between the two boards, but I'm not connecting the reset and chip_en pins. Instead, I'm using a software method for the esp32c3 to enter the download mode.

** Problem description:
I'm using the example esp32_example, and I works fine for me right now. The problem is that I want the esp32c3 board to reboot after the firmware is successfully flashed. Thus I call the function esp_loader_flash_finish(false) after the flash tasks are completed. However, this command failed and I cannot figure out why.

Log output
