Topic: Updating Firmware STUCK ON STEP ONE

After much trial and error flashing my ESP8266 get remotexy to work, I have come to the conclusion I need some guidance.
Ive been stuck at step one now for sometime. My dabbling with non Windows based firmware tools would bring belly laughs/ tears to the gurus.
I am attempting to flash a wemos mini which has 32Mbit / 4MB and a Duinotech MEGA board with an integrated ESP8266 again with 32Mbit / 4MB. In some places the onboard wifi  is referred to a  “LOLIN(WEMOS) D1 R2 & mini” and others as a generic 8266 Module. I have attempted flashing using both settings.
I revisited the remote xy site and installed esp8266_nonos_sdk_v1.4.0_15_09_18_0.rar using and updated download tool V3.8.5,
I finally got reasonable responses to AT+RST and AT+GMR.  Some where between this version and the most recent version is the UNICORN I'm after.
Could someone share their successful settings for using the ESP8266 Download Tool, eg memory addresses and latest versions of bin files that work with REMOTEXY. (I have found suggestions where people have mixed and matched bin files from different versions of  the ESP8266 NONOS SDK).
Thanks in anticipation
David

Looking forward to getting tp the stage where I can ask for help by putting up a sketch or two.

Re: Updating Firmware STUCK ON STEP ONE

I found these settings to work
This is for an Jaycar mega with wifi on board.
Flash size is 32Mbit
(apparently it is the same as wemos mini)
and turning OFF  all jumpers except 5,6 and 7- to up-date the firmware .


from the file 3.0.2
esp_init_data_default_v08.bin @0xfc000
blank.bin @0xfe000
boot_v1.7.bin @0x00000
bin\at\512+512\user1.1024.new.2.bin @ 0x01000
bin\at\512+512\user2.1024.new.2.bin @ 0x81000

After the tool shows FINISHED
Turn OFF switch 7 - reset and try the AT commands in a serial  monitor.
AT+RST
and
AT+GMR
