Flash size 4MB (Sonoff Pow, Electrodragon…) -Tesp8266.flash.4m.ld #259

Closed MacWyznawca closed 7 years ago

MacWyznawca commented 7 years ago

I changed the settings in PlatformIO.ini (for Electrodragon) to Board = esp12e -Tesp8266.flash.4m.ld

And now in Info I have: Flash size: 4096kB Program flash size: 4096kB Program size: 430kB Free program space: 592kB

Earlier I had (with Board = esp01_1m and -Tesp8266.flash.1m64.ld): Flash size: 4096kB Program flash size: 1024kB Program size: 429kB Free program space: 508kB

Would anyone be so good and explain to me, where does the difference in memory available for the program and if something extra memory can come in handy?

What do you think does the -T option do? It selects the linker to use and in your first case it links a 4096kB flash image while in the second it links the 1024kB flash image with 64k SPIFFS area. The ElectroDragon has 4M flash while (most) Sonoffs have just 1M flashes. I need the spiffs area to store my settings although I'm not using spiffs filemanager to handle it.

OKAY! Thank you and I read more in the documentation.

From my tests: With the setting -Tesp8266.flash.4m.ld Electrodragon saves the settings in your firmware. I also checked the OTA update several times and it works in Electrodragon.

By the way: today I have to get new relays with ESP12f from Electrodragon (low voltage and multi-channel relay). How will I test to let you know what they are worth ;-)

Did you get the new relays? How do they perform?
