Hi
We want to integrate PVRSGX Graphics SDK with board similar to Centaurus (TI814x).
We are using Graphics_SDK_setuplinux_4_03_00_01.bin.
Our base kernel is 2.6.34.
As per the wiki pages available we were able integrate the file system changes and can load the kernel modules.
When we run pvrsrvinit utility it hangs in
ui32SGXRevision = OSReadHWReg((IMG_PVOID)((IMG_PBYTE)pvRegsLinAddr), EUR_CR_CORE_REVISION);
Because of this it gives PowerVR device not found.
Please find below the log for reference
./pvrsrvinit
