1- Yes, you need a USB-Serial adapter. Because the ESP8285 modules has its own microcode, and the chip´s Rx/Tx lines are hooked to the Sipeed chip, you need to access those lines to flash the ESP chip. 2- I don´t know about the specificities of MacOS, but serial flashing the ESP8285 did not work for me too, although I did not have the same error. For me the -m DOUT option was not supported _probably due to the specific version of the ESP8285 mounted on my board (Maix Dock Suit with LCD and camera). Removing the -m DOUT from the flash commandline worked.
3 - don´t know 4- I don´t know about the OTA firmare, but I suppose it allows to flash the ESP8285 firmware only.
Try changing -m DOUT
to -m dout
?
After reading the document I'm not quite clear about how to get Wi-Fi work on a Maix M1w. Here are some elementary questions:
