bootloader.o exec format error

[antifm]

Running into errors when building custom firmware and found no resolve in the issues forum. Could I please get some assistance?

• Pycom board: FiPy

• Firmware: (sysname='FiPy', nodename='FiPy', release='1.20.2.r6', version='v1.11-c5a0a97 on 2021-10-28', machine='FiPy with ESP32', lorawan='1.0.2', sigfox='1.0.1', pybytes='1.7.1')

• Operating system: Linux raspberrypi 5.10.17-v7+ #1414 SMP Fri Apr 30 13:18:35 BST 2021 armv7l GNU/Linux

• Exact steps to cause this issue

  1. I completed the setup as per instructed in README file.
  2. Then tried to build the firmware with make BOARD=FIPY clean - no problems there
  3. Then I tried to run make BOARD=FIPY which yielded the error below

• What you expected

  • I expected the firmware to successfully build however this was not the case.

• What happened instead

  • Instead I got the following error:

    
    $ make BOARD=FIPY V=1 
    Use make SECURE=on [optionally SECURE_KEY ?= secure_boot_signing_key.pem] to enable Secure Boot and Flash Encryption mechanisms.

Resolved after @livius on pycom forums pointed my Operating System out.

I had used RaspberryPi as I was initially struggling with using Windows Subsystem for Linux (WSL) and following the instructions listed on github. I had extracted the xtensa gcc compiler tar.gz file incorrectly, by using WinRAR onto my Ubuntu file system - this must've corrupted some of the data.

This time, I copied the tar.gz file into the Ubuntu file system and extracted it using Linux commands, the process had run smoothly and I was able to build a binary file.

Hope this can help others!
