ESP8285 AT firmware programming

Postby michael.ughetti » Fri Nov 10, 2017 11:38 pm


I'd like to program the AT firmware on an ESP8285 (custom board).
I've found my way through programming but I got an error at startup.
See attached pictures of programming screen and error.

Could you explain to me what I'm doing wrong ?
Bonus question : is there a way to start with 115200 baudrate instead of 74880 ?

Best regards,
Michaël Ughetti

Maybe you can have a try with the SPI mode "DIO" while downloading the firmware.
Not sure if my suggestion can solve your problem, but you can have a try. :?
