Failure Building Firmware 1.6.9.b1- Error 126 executing make -flash

[rdixey]

Hello All,
This is my first time through compiling the Firmware so I hope someone with experience doing this can give me some guidance since I've run into a wall. Following the instructions here: https://github.com/pycom/pycom-micropython-sigfox/blob/master/esp32/README.md I did a fresh clone of pycom-esp-idf, installed and built toolchain, and did a fresh clone of pycom-micropython-sigfox.

Error While Executing: make BOARD=LOPY LORA_BAND=USE_BAND_915 flash
bash: ../mpy-cross/mpy-cross: Permission denied
../py/mkrules.mk:116: recipe for target 'build/LOPY/release/frozen_mpy/_boot.mpy' failed
make: *** [build/LOPY/release/frozen_mpy/_boot.mpy] Error 126

Following are all the details:

@rdixey mpy-cross is missing. This is the Python compiler.
If you're in esp32, go to ../mpy-cross and execute the command:
make all
after that, got back to ../esp32 and execute
make BOARD=LOPY LORA_BAND=USE_BAND_915 flash

[jmarcelino]

Read the ESP32 specific README, it's all there :-)

https://github.com/pycom/pycom-micropython-sigfox/blob/master/esp32/README.md

First step.

[rdixey]

@jmarcelino Yes - Thats exactly what I have been following to get this far.

[jmarcelino]

@rdixey

I'm sorry didn't notice you wrote that already!

So you built mpy-cross but it's saying permission denied. Can you check it's permissions, i.e. it's executable and if the user is right etc?

ls -l ../mpy-cross/mpy-cross should do it

[rdixey]

@robert-hh Well that certainly was a problem. Thanks:~) Honestly I had done the mpy-cross - make all yesterday and did not notice an error while compiling. But on your point I went back and found there was no mpy-cross executable file in the mpy-cross folder. So i did the make twice more until the mpy-cross executable appeared. Weird?

Now when I do: make BOARD=LOPY LORA_BAND=USE_BAND_915 flash
I get much farther but error again while compiling as follows:
Any suggestions.

@rdixey
don't do make BOARD=LOPY -j5 TARGET=app clean but just make BOARD=LOPY -j5 TARGET=app

[Colateral]

@rdixey I have the same problem. Do you have some workaround?

[robert-hh]

@Colateral Did you build mpy-cross? It is the Python byte code compiler needed in the build process. to do that, do to micopython/mpy-cross and issue:
make mpy-cross
then got back to microypthon/esp32 and retry the build. If it fails at the step, when loading into the device, the access rights for the port may be wrong. You can then either run under sudo, or put your account into the dialout group with:
sudo addgroup <yourname> dialout
