#34892 Good evening,
I am trying to program an ESP8266-WROOM-02 via ESP FLASH DOWNLOAD TOOL V1.2 with an AT firmware.
I succeed but one ESP8266 AT firmware (from github) does not work.
1) which HW configuration should I use on the WROOM-02? (clock, SPI, RFI, Flash size..)
2) do you know some AT firmware or other demo firmware to upload to the module in order to test it?
Thank you
