- Wed Oct 15, 2014 3:30 am #1658 I had compile SDK exaple using this instruction https://nurdspace.nl/ESP8266/First_setup
Then I upload firmware to esp modele ant it not work. When UART set to 75000 I see -

Code: Select allets Jan  8 2013,rst cause:1, boot mode:(3,0)
ets_main.c

When 115200 - some garbage and no reaction to any input in terminal
ps sorry for my english
thanks

- Wed Oct 15, 2014 3:02 pm #1677 that message "ets_main.c" means the bootloader have not found any firmware at 0x0 (and/or? 0x40000

I don't want to be human! I want to see gamma rays, I want to hear X-rays, and I want to smell dark matter ...
I want to reach out with something other than these prehensile paws and feel the solar wind of a supernova flowing over me.

- Thu Oct 16, 2014 12:46 am #1701 If I use sdk 0.9.1 for compile, before uploading AT exaple firmware(0x00000.bin and 0x40000.bin), do I need upload full firmware 0.9.1(about 520k) or not?
PS I used module esp-03 with 14pin, to start I pull gpio15 to gnd. With full firmware(520k) its work as expected

Maybe you just need re-flash your FW into module; or you didnot specify the right offset when you flash
