How to get 4.0 running

[DonTSan]

I've installed Sming 4.0 and esp-open-sdk on 2 different computers and a virtual machine (all Ubuntu type). I tried Wemos d1 mini, Node-MCU and a self-made circuit board. I don't get even Basic_Blink running. Sming 3.8 (esp-open-sdk 2.0) works fine on all boards. Connecting on 74880 BAUD shows following information: **_ets Jan 8 2013,rst cause:2, boot mode:(3,6)

However, 'Flashinit' does not make any difference. Does anyone know what's going wrong with flashing? Any help would be highly appreciated.

Try SPI_SIZE=4M for the NodeMCU. See https://smingdev.readthedocs.io/en/latest/_inc/Sming/Arch/Esp8266/Components/esptool/index.html and https://smingdev.readthedocs.io/en/latest/_inc/Sming/Arch/Esp8266/Components/esp8266/index.html

make config-clean

Thanks both of you. I'm going to start a reading session and will come back later.

It's running. I started with , then and at last Thanks again.

I guess my sentence is not shown completely. The sequence I did was:

• make config-clean

• make flashinit

• make flash SPI_MODE=dio SPI_SIZE=4M
