Using ESP-IDF on a Lopy/Pygate

[Gonçalo Ferreira]

Hi, I was trying to program my Lopy4 that is going to be connected to a pygate in C/C++. For that I installed ubuntu on a VmWare Virtual Machine and installed ESP-IDF. I followed the steps of https://github.com/pycom/pycom-esp-idf and https://github.com/pycom/pycom-micropython-sigfox and got this directory's on my esp directory

I exported the paths from both xtensa-esp32-elf/bin and pycom-micropython-sigfox.git. Nevertheless when i trie to make BOARD=LOPY4 i got this error

how can i get this to work? Sorry if the question is stupid but its the firts time i use ESP-IDF and make.
Dont realy know also how can I set the lopy as a pygate expansion board so i can use the example codes in pycom-micropython-sigfox.git.
Thanks for the help

@Gonçalo-Ferreira You have to checkout the requested version. Go into the esp-idf directory and run:

git checkout 3394ee5

Then this error message should be history.

Note: You will get a warning that the repository is now in "detached HEAD" state. Sounds cruel, but is not critical.

git checkout 3394ee5

Hi @robert-hh , thanks for your reply!
I did that

but it still gives me the same error

can you help me?

@Gonçalo-Ferreira @robert-hh I figured out the problem,, I was not exporting the correct path.
Now i make make BOARD=LOPY4 and it says i dont have pyserial intalled and i dont find de README.md with the instructions to install it.
Can you help me?

Srry, i was able to resolve the Pyserial problem. The make BOARD=LOPY4 worked oaky, but when i do make BOARD=LOPY4 flash its says that the port is not correct. Then i saw my usb devices and my board is the ttyACM0. I did make ESPPORT=/dev/ttyACM0 flash and this error happended

what is wrong?
srry for the questions mentioned before

[Gonçalo Ferreira]

@Gonçalo-Ferreira if i dont use "sudo make" it gives me permission denied on open the port

[robert-hh]

@Gonçalo-Ferreira sudo uses other environment variables. So you are back to the old error. For port access you have to add you user name to a group with the name dialout. Ask google how to do that.

For Ubuntu and other Debian-like Linux :

$ sudo usermod -a -G dialout <username>
