ARM Login #2

Open Tomhariless opened 5 years ago

Tomhariless commented 5 years ago

Hi, I am trying to use the kernel and the roots on the SD card. I get the system booted, but have a problem with the arm login. Could you provide the user name and the password so that I can actually run the system please

nikkatsa7 commented 5 years ago

Hi! As you can see on this page, you must use the default username ubuntu and the password temppwd.

Tomhariless commented 5 years ago

Many thanks for the password and username, I have successfully login to the system. Then I tried to use the make command to build the executable file of HOG, and it succeeded. However, when I use ./HOG to run the application, it returns me an error as Memory mapping couldn't be performed.

terminate called after throwing an instance of 'std::runtime_error' what(): Memory mapping couldn't be performed Aborted (core dumped)

I just wonder if you have come across the same problem before or is there any solution for that?

nikkatsa7 commented 5 years ago

Try: sudo ./HOG.

Wow, that's a quick reply. I have tried sudo, but it seems like the ubuntu is complain about: ####################### sudo must be owned by uid 0 and have the setuid bit set ####################### I have also view the dmesg of the system.

Tomhariless, did you manage?

Hi Dorin,

I have not manage that. Unfortunately, the sudo problem is still there. I used the petalinux to build another Linux application,with my customized hardware platform on Zedboard.
