Hello,

I am using MBDT for s32k3xx.

Please can you help with tutorial/documents for how to use freemaster with MBDT.

I am using free master to view adc value.Can you guide how to build model and then how to view value on FreeMaster.

First of all, I need to mention that the FreeMaster tool can be used through multiple connection types. I suggest you to use one of the following two based on your available hardware:

Using a debug probe, and access the target microcontroller memory over BDM communication.

You can find a topic related to this type of connection at the following link on our community:

Using a serial communication.

In order to establish communication between the evaluation board and the FreeMaster tool, you must use a USB2Serial converter. The software and hardware configurations that need to be verified before using serial communication are covered in the following topic:

FreeMaster, ExternalMode, or PiL can all use the serial communication configuration.

Regarding the question on how to use FreeMaster, you can take a look at the following video, which presents a simple application that uses the FreeMaster tool together with the S32K1xx toolbox. The S32K1 workflow is a little bit different from the S32K3 one that you are using, but you can focus only on the last part, which is about the FreeMaster configuration:

The main idea here is to successfully generate an executable .elf file and then use it in FreeMaster to read the desired variable values.

Hope this helps.

Have a nice day,

Victor
