Hi, I'm trying to follow your reciepe but at point #4 I get:

Code: Select allMicrosoft Windows XP [Wersja 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\esp_iot_sdk_v0.9.1\examples\at>make
CC driver/uart.c
make: execvp: c:/esp_iot_sdk_v0.9.1/xtensa-lx106-elf/bin/xtensa-lx106-elf-gcc: Bad file number
make: *** [build/driver/uart.o] Error 127

what am I missing here?
Thanks!

- Sun Nov 09, 2014 3:47 am #2359 You do have the "xtensa-lx106-elf" folder inside the "esp_iot_sdk_v0.9.1 folder"?
One of the downloads I grabbed didn't have it...

- Sun Nov 09, 2014 5:43 am #2361 nope but the Makefile seems to reflect that situation... anyway can you please post an archive containing all of necessary stuff in proper directory structure? I mean an archive that works
Thanks a lot!

- Tue Nov 11, 2014 10:32 am #2473 First Link in second post above contained everything I needed... otherwise it was a case of finding individual packages and installing separately...

The zip contains three folders...

• esp_iot_skd_v6.9.1 (this contains the xtensa-lx106-elf folder)...
• MinGW
• Python27

required for Windows users...

I just followed the instructions above and compile went without a hitch but I did need to download the Python27 windows install as I had a missing DLL...

I assume you could grab the git for xtensa-lx106-elf, run the make file and then add the xtensa-lx106-elf folder manually...
There's a Flash download tool here: http://bbs.espressif.com/viewtopic.php?f=7&t=25 but I haven't tried it...
