Dear TI DM3730 guru,
I’m
currently facing an issue related to the PowerVR library on DM3730 under
Windows CE 6. We ported a TI OMAP 3530 6.15 BSP to work on a DM3730 with
the latest PowerVR SDK ( as the one available in 6.15 BSP isn’t compatible with
the DM3730). When using the graphic acceleration using OpenGL ES the system
hangs in the Windows CE interrupt service handler. By investigating on the Data
Abort exception we have, we identified that it occurs on a reading of the INTCPS_SIR_IRQ register.
This strange errors means that the interrupt controller register isn’t readable at the time of the request. This request is performed to identify the source of the interruption and is done by the interrupt handler. This interrupt handler is called for every interruption occurring on the system, so there is no reason to have this register inaccessible.
So we are suspecting that the clock for this register is disable by “some one” but no drivers available on the platform uses this register clock. Our focus then is on this PowerVR library.
Could you please confirm that the PowerVR library is disabling the MPU INTC clocks ?
Regards
Nicolas
