Sonoff Basic compiling error

[titomontes]

Hello Stefan

I´m trying to compile your fork to flash it onto a Sonoff dual R2, but I´m getting only errors; It seemed (like 20 attempts ago) that the problem would be low memory, so I tried the sonoff basic option, but I get this:

Compiling .pio\build\sonoff-basic\src\sonoff.ino.cpp.o Linking .pio\build\sonoff-basic\firmware.elf c:/users/tito/.platformio/packages/toolchain-xtensa/bin/../lib/gcc/xtensa-lx106-elf/4.8.2/../../../../xtensa-lx106-elf/bin/ld.exe: .pio\build\sonoff-basic\firmware.elf section .text' will not fit in regioniram1_0_seg' collect2.exe: error: ld returned 1 exit status *** [.pio\build\sonoff-basic\firmware.elf] Error 1 [ERROR] Took 17.14 seconds Environment sonoff-basic [FAILED]

Is there an already compiled flashable .bin file? (with core 2.3?)

Thanks again for your work!

@titomontes

Your issue is that you have Platformio v4 and requires to add build_dir = .pioenvs under [platformio] inside the platformio.ini file as:

[platformio]
src_dir = sonoff
build_dir = .pioenvs

This is already updated in main Tasmota

Have you tried using Gitpod for compilation? It ought to work in a very similar manner to what is described in the Tasmota wiki Gitpod article other than pointing to your code branch.

Hi gents, thanks for bringing up the incompatibility with Platformio V4. Will update sources now

Hello again

I´m sorry to say that, compiling in core 2.3 still fails:

Linking .pioenvs\sonoff\firmware.elf .pioenvs\sonoff\libFrameworkArduino.a(core_esp8266_main.cpp.o):(.text._ZL12loop_wrapperv+0x4): undefined reference to setup' .pioenvs\sonoff\libFrameworkArduino.a(core_esp8266_main.cpp.o):(.text._ZL12loop_wrapperv+0x8): undefined reference toloop' .pioenvs\sonoff\libFrameworkArduino.a(core_esp8266_main.cpp.o): In function loop_wrapper()': core_esp8266_main.cpp:(.text._ZL12loop_wrapperv+0x21): undefined reference tosetup' core_esp8266_main.cpp:(.text._ZL12loop_wrapperv+0x2d): undefined reference to `loop' collect2.exe: error: ld returned 1 exit status

Core 2.5.2 works well though, although there are stability issues...

@meingraham Thanks a lot for pointing it out. I will surely use it in the future

@ascillato @stefanbode, did you have a look at this?

[stefanbode]

Yes fine. I think you can use it without any modification. I do not see any changes I need to do. Anyhow: I do not agree to change the my_user_config.... you can all do this in the override file. Just follow the exampled and undef define the variable to override existing values.
