- Sat Sep 10, 2016 9:37 am #54810 I've installed Cherts' DevKit for Windows v2.1.0. DOS command make works great immediatly ((I don't want Eclipse) contrary to many other installs I've tried unsucessfully on my Win7 32bits. Great job Cherts, thank you !

All the projects of the "examples" folder compile well into .bin (1wire_ds18b20, blinky, at, dht22_thingspeak...) except nodemcu-firmware.
With nodemcu-firmware, compile and link are ok (ouput file eagle.app.v6.out is produced) but when generating .bin,I get this error :

Code: Select all"LoadLibrary(pythondll) failedLe module spÚcifiÚ est introuvable."

Solution : path error in file "examples/ESP8266/nodemcu-firmware/Makefile" must be corrected

Code: Select all=> change
ESPTOOL      ?= ../tools/esptool.exe
to
$(SDK_TOOLS)/esptool.exe

Problem is the nodemcu-firmware of the DevKit's example is too old (V0.9).
Anyone know how to compile the up-to-date version ( nodemcu-firmware V1.5.4.1) ? I've downloaded it and try to compile it but get plenty of errors. I don't know enough make to change Makefile.

- Sat Sep 10, 2016 4:44 pm #54829 Maybe a clue to the problem of compiled firmware not working anymore and sending out error messages at 74880bds (garbage with another comspeed) instead of jumping to main() :
1) project hello_world compiles and works fine ("hello world" sent every 1s)
2) project hello_world_cpp compiles but sends garbage like above

Does the problem comes from some options for gcc when upgrading Cherts' toolchain to V2.10 ?

nodemcu-firmware from the Cherts' examples folder (V 0.9.6) compiled in the same conditions works fine on ESP-1 and ESP-12E. Funny, it works even when compiling & flashing ESP-12E (4MB) with the exact same parameters than ESP-01 (512Kb), with nodemcu saying something like "adjust memory" at the first boot and then booting without complaint every time.
But no such luck with the latest nodemcu-firmware from web repository, so I am pretty sure the problem does not come from the flashing and default binaries.
