'MXCHIP AZ3166 mxchip_azure_iot.bin does not exist'

[umairakhtar3]

Hi,
I have been trying to install MXCHIP AZ3166. I followed the instruction on https://github.com/azure-rtos/getting-started/tree/master/MXChip/AZ3166 and https://learn.microsoft.com/en-us/azure/iot-develop/quickstart-devkit-mxchip-az3166-iot-hub. First I tried to install through IoT hub method. Cloned the repository and followed step1,2,3 but after I run 'getting-started\MXChip\AZ3166\tools\rebuild.bat' file and go on to step 4 to find this 'getting-started\MXChip\AZ3166\build\app\mxchip_azure_iot.bin' file to flash. It does not exist in that location or in other words, it does not get created.

So i run the process all over again. Same problem but when I check CMake version it says ''cmake' is not recognized as an internal or external command'. Even though, it is included in clone. Plus, I installed Cmake separately as well.

Kindly let me know how to fix this issue.

Thank you

Hello,

Cmake.exe isnt available on your path, so the source in unable to build and you should be seeing an error on the console.

You can either:

1. Add cmake.exe to your system or user path manually
2. Reinstall cmake, and choosing one of the "Add CMake to system PATH" options, and then restart your console.

So I tried this and It worked and I was able to flash it to iot device root folder. I set Baud rate to 115,200 and corrected USB port in Termite after checking with device manager. Termite gives this error when I press reset after connecting device and completing setting step in Termite:

Initializing WiFi
ERROR: wifi_ssid is empty
ERROR: wifi_init (0x00000043)
ERROR: Failed to initialize the network (0x00000043)

I am putting the following info in 'azure_config.h* file:

WIFI_SSID : "#r******"
WIFI_PASSWORD: "**********"
WIFI_MODE: "WPA2_PSK"

IOT_HUB_HOSTNAME: "r******.azure-devices.net"
IOT_HUB_DEVICE_ID: "j*****"
IOT_DEVICE_SAS_KEY: "r*****"

I did not put DPS information because I want to test just IoT hub connectivity. Am I putting the above information in the file in the correct form?
Because Termite does initiate WIFI and gives the error mentioned. Let me know how it can be fixed.

Thanks a lot

I would say that either the wrong azure_config.h was edited (make sure it's the one in the MXCHIP/AZ3166/app dir), or you need to recompile the binary again to pull in the changes.

At this time, the WIFI_SSID in the mxchip bin file is empty.
