- Sat Jan 10, 2015 4:00 pm #6935 I was able to compile/flash/run it on Linux without any problems by doing following:

1. Install esp-open-sdk. This was as easy as cloning repository and calling make.

2. Set path to the toolchain created in step one, some thing like

Code: Select allexport PATH=/home/k/BUILD/esp-open-sdk/xtensa-lx106-elf/bin/:$PATH

:

3. Clone nodemcu-firmware repo, call make (without any -jX parameter, for some reason this does not work for me).

4. Use esptool.py to prepare and flash images:

Code: Select allesptool.py elf2image app/.output/eagle/debug/image/eagle.app.v6.out
esptool.py write_flash 0x00000 app/.output/eagle/debug/image/eagle.app.v6.out-0x00000.bin  0x10000 app/.output/eagle/debug/image/eagle.app.v6.out-0x10000.bin

However, when attempting to flash I get the following error:

Code: Select allConnecting...
Erasing flash...
Writing at 0x0000ac00... (100 %)
Erasing flash...
Traceback (most recent call last):
  File "../esp8266/esptool.py", line 400, in <module>
    esp.flash_begin(len(image), address)
  File "../esp8266/esptool.py", line 178, in flash_begin
    raise Exception('Failed to enter Flash download mode')
Exception: Failed to enter Flash download mode

And upon boot the chip keeps spilling data at an unknown baud rate. :s
Flashing a pre built firmware works fine.

Edit: I used 0x1 instead of 0x10..0
Btw, for ease you can just use "make flash" for flashing.

Yep, that's working as of yesterday, it seems. Introduced in this commit - https://github.com/nodemcu/nodemcu-firm ... c04bde7c3c I guess.
