- Tue Jul 21, 2020 5:45 pm #87994 I am not actually new in esp8266, but forgot most things of it. Now i trying again to explore it for a small home project.

Company i am working in, produses some hardware on esp8266 chip - and so i have multiple esp8266 modules from usless devices(which i got from our hw developers). But this modules not the same modules from aliexpress(for example).
https://router-help.com/
here is pdf about my module https://manualzz.com/doc/6515184/airm2m ... anual-v2.9

So this is typical esp8266 - and it's work just fine - no problems.

For developing i chose Visual Studio(cos i sw developer and VS looks like habitual for me) with plugin for it https://bbs.espressif.com/viewtopic.php?t=3577

nevermind...

I wrote simple firmware and flashed it to module with bootloader "boot 1.6" - firmware started - all just fine.

But i no need any bootloader, so i swithed to nonboot mode with generating .flash+.irom0text. Code compiled and flashed without any errors. But firmware not started, see log below(74880 speed)

I thought problem in SPI flash size - so my flash id is 1440C8, so ie must be 8mbit = 1 mb

For experiments i tried to set 512 kb and 1 mb - but nothing changed.

Here build log

PS
I use old nonos sdk 2.0 (cos it was provided by espressif VS plugin, but i don't think that is root of problem)

I'm using VS too but never used that plugin cause I prefer to wrote my own VS tasks

looking at your build report it seems that the eagle.irom0text.bin is placed at 0x40000
while I remember that when building without the boot it has to be placed at 0x10000
(I copied the following message from the Makefile, but you can check the manuals too)

Code: Select all        @echo "No boot needed."
        @echo "Generate eagle.flash.bin and eagle.irom0text.bin successully in folder bin."
        @echo "eagle.flash.bin-------->0x00000"
        @echo "eagle.irom0text.bin---->0x10000


that should explain why the same code works with the boot and it doesn't without it
so I think you should check the building configuration
