| Responses: | |
| Hi Sam, Are you using the PSDKLA 3.04 filesystem or vision-sdk 3.04 filesystem? Vision-sdk filesystem doesn't provide QT applications | |
| Hi Ramprasad, I'm using PSDKLA3.04 filesystem . Regards, Sam. | |
| Hi Sam, vDRM feature can be currently used only with VISION-SDK. It can not work with PSDKLA3.04. | |
| Hi Ramprasad, So how can I run the QT app in the PSDK3.04? The weston start up failed, as you see . Regards, Sam. | |
| Hi Ramprasad, Maybe I made a mistake. I just want to run a QT app by using PSDKLA3.04. Can you give me some suggestions? Thank you very much . Regards, Sam. | |
| Hi Sam, If you want to use only PSDKLA, please download latest SDK from this link downloads.ti.com/.../index_FDS.html and prepare SD card. This should work fine for QT application. You don't need to make any changes in powervr.ini Thanks Ram | |
| Hi Ram, Thanks for your reply. I'm confusing the VSDK with the PSDKLA. And now I can see the matrix-gui. Thank you ! Regards, Sam. | |
