Hello everyone,

I am trying to flash my RD-PQ test device (from 2.2.0 to 2.2.1)…. everything went well until the installation of the Mali DDK. I am using this tutorial:

https://source.tizen.org/documentation/reference/flash-device

1)- Arriving to the “Using 3D Acceleration” section, I didn’t understand how to switch between host and target?

2)- in the opengl-drivers.zip folder, I found two subfolders “mobile” and “wearable”, what is the difference, I guess that I must use the “mobile” folder.

I tried to run the following command, but I got this error:

~/tizen-sdk/tools$ sdb -d root on
No command 'sdb' found, did you mean:

 Command 'gdb' from package 'gdb' (main)

Here is a screenshot of my tools folder:

What’s wrong?

Thank you.
