<![CDATA[flash status]]>I use M5Stack Basic.
Executing the command "esptool --port COM3 write_flash_status --non-volatile 0", I got the following result.
I would like to know the meaning the code of "flash status" as 0xff42 or 0xff40.
I could not find any document regarding it.
Would you tell me the web site for the "flash status" information?

esptool.py v2.6

Chip is ESP32D0WDQ6 (revision 1)

Thanks in advance.
