error using make BOARD=LOPY4 TARGET=boot

[HelalBR]

Hello guys,

I'm having some troubles trying to compile my own firmware. I followed every step in this tutorial:
https://github.com/pycom/pycom-micropython-sigfox
but when i run MAKE BOARD=LOPY4 TARGET=boot i get the following error:

Use make SECURE=on [optionally SECURE_KEY ?= secure_boot_signing_key.pem] to enable Secure Boot and Flash Encryption mechanisms.
Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.

I tried with different boards (WIPY, LOPY etc) and I get the same error. Any ideas of what is causing this?

Thanks in advance.

Did you check out the proper version of esp-idf? In the esp-idf directory, issue the command

git checkout 4eab4e1

@robert-hh , I didn't check. i issued the command and everything works fine. Thanks for the fast reply.

root@alanhelal-virtual-machine:/root/pycom-esp-idf# git checkout 4eab4e1
M components/aws_iot/aws-iot-device-sdk-embedded-C
M components/bt/lib
M components/esp32/lib
M components/esptool_py/esptool
HEAD is now at 4eab4e1 esp32: Place gettimeofday inside IRAM.
root@alanhelal-virtual-machine:/root/pycom-esp-idf#

@Xykon I didn't notice this command. I was used to do everything just following the directions on this repository. Thanks for the clarification.

Problem solved.

[robert-hh]

If the problem is solved, may I ask you to close the issue?

For anyone else reading this... we have reverted the master branch of pycom-esp-idf back to the correct commit needed to build the stable firmware.
