[nd88]

Followed the instruction provided in the tutorial.

1. Uploading root certificates to IoT Hub
2. Verify in Azure portal
3. then ./buildScript.sh
4. export OPENSSL_CONF=/simw-top/demos/linux/common/openssl_sss_a71ch.cnf
5. ./azure_imx_connect --deviceid "test-device" --keypath /opt/simw-top/pycli/Provisioning/azure/528951245135856629515010_device_reference_key.pem --rootpath /opt/simw-top/demos/linux/azure/azureRootCA.pem --devcert /opt/simw-top/pycli/Provisioning/azure/528951245135856629515010_device_certificate.cer --hubname my-iot-hub.azure-devices.net --username my-iot-hub --payload "Hello World"

it fails with

any idea what could be the cause, not much info for me to trouble shoot on this. May I know is the error is on A71CH or connection to azure?

@Kan_Li  I am using the MW you suggested in one of my previous post.

https://www.nxp.com/webapp/Download?colCode=SE-PLUG-TRUST-MW

and I am using MCIMX6UL-EVKB-ND with A71CH

Hi @nd88 ,

Thanks for the clarification!

Have you followed the steps listed in the docs along with the MW?

For example,

and have you ever tried other demos such as "ex_ecc"? Did it also run into issue like this?

Have a great day,
Kan
