build of python3 of MPLAB

Hi,

I am using Curiosity PIC32MZ EF Bundle and Java SE 10.0.2 and Python 3.7.0 (Homebrew macOS PMJ and Pyenv global 3.7.0) and MPLAB V5.05 and XC32 V2.10 on MacBook macOS edition:).

In Connect to AWS IoT - a:freeRTOS MQTT Hello World sample 1.4.1 of an AWS.
How should a build of python3 of MPLAB be done?
(Is /absolute path/python3 designation OK? Does Python code of a:freeRTOS OTA need a pem file of a certificate?)
How should a use xc32-objcopy of < makeCustomizationPostStep> of MPLAB be done?
(Is absolute path designation OK? /applications/microchip/xc32/v2.10/bin/xc32-objcopy -I ihex ${ImagePath} -O binary ${ImageDir}/mplab.${IMAGE_TYPE}.bin && python ../../../common/ota/bootloader/utility/ota_image_generator.py -b ${ImageDir}/mplab.${IMAGE_TYPE}.bin -p MCHP-Curiosity-PIC32MZEF)

Thanks.

Postscript.
pyOpenSSL was used.
Reinstallation of an attribute error of Python takes time and effort.(When the command of python is carried out from a terminal, it attribute error come out:-?)
It was seen using this certificate:).

a:freeRTOS V1.4.2 was doing pass setting of xc32-objcopy by an environment variable.

A pass passes?

OTA is stopped.

Free balloon call!

Hi,

This sample is difficult.
It was PIC pickles.
The translation is also difficult:).

By a absolute path of my Python, build success!
Free balloon!

List:
a:freeRTOS V1.4.2
It was seen using this certificate.
VeriSign-Class 3-Public-Primary-Certification-Authority-G5.pem to aws_ota_codesigner_certificate.pem
The name Python code uses, it was changed.
This aws_ota_codesigner_certificate.pem file was put in a lower folder.

I could do a terminal USB connection.
ls -l /dev/tty.*
cu -l /dev/tty.usbserial-A999OFI9
screen /dev/tty.usbserial-A999OFI9 115200

But new error information.
WiFi can't be connected:-.

Thanks,

Postscript.
A channel of WiFi was an error of a race condition.
It was settled by channel change in the WiFi router.
Thanks all:)!
