Changing AT-Firmware to Micopython, img-file is not persistent after reset

Hi,
i could upload some other firmware using normal .img files.
But that image is not persistent, after reboot the Bootloader responds with:

secboot running…
CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC

Even after: Flashing using PA0 = low condition with reset

“w600tool.py” -p COM15 --upload-baud 115200 --upload “D:\Work_Air602_firmware\W60x_MicroPython_1.10_B1.5_img\W60X_MicroPython_1.10_B1.5_img\1M_Flash\wm_w600.fls”

fails with:
Opening device: COM15
Error: IMG file is required for secboot

I thought (having read “WM_W60X_Firmware Generation Guide + WM_W60X_SECBOOTFunction Guide”) that resetting and PA0 = low
will open the Bootloader for .fls Images?

Using the Sendfile option in SSCOM V5.13.1
Also fails (with reset PA0=low and sending ESC (1B) -sequences) :

Could you please describe the process how to flash the MicroPython- or other images persistently by replacing the useless (!) original AT-command flash image or adequate bootloader?

Resolved by myself with download.py:

D:\Work_Air602_software\w600tool-0.1>python .\download.py -p COM15 -b 115200 --upload D:\Work_Air602_firmware\W60x_MicroPython_1.10_B1.5_img\W60X_MicroPython_1.10_B1.5_img\1M_Flash\wm_w600.fls

This leads directly into the next question:

This method is not applicable to the “Air602 WiFi Development Board”.

Any suggestions?
