Hi,
Thanks for your reply!
This statement means that the installation is unsuccessful on Windows PC due to the same error that mentioned earlier but after the unsuccessful installation, a folder is created which is extracted info from exe file that exist all the files, documentations, and examples. Since I am running on my Ubunutu Laptop S32DS for Power Architecture without issue, I tried to run the ENET ping example existed in the extracted folder on my S32DS for PA. But, as mentioned, the Cpu.h is missing in the extracted folder from exe file of S32SDK. I assume that this can be generated when S32SDK can be installed properly which in my case does not, due to the last reason. So what should I do? in my S32DS for PA on my Ubuntu, there are not any examples for S32R274, that's why I need the Cpu.h file or I need to install the S32DSK properly. What should we proceed?
The following is the main file of ENET ping example but the folder does not include the Cpu.h header file.
