Am running 12.4 tools and I can't get the SG_I2C_CONTROLLER_S6_PLBW controller to initialize. It seems to hang somewhere in the function, in that I never get a return code (bad or good). What should I be checking for?

I am looking at this.
There are other reported issues with attempts to use the 12.2 EDK projects with 12.4.
I will probably end up posting a new version of the designs, specifically for 12.4 ...
stay tuned ...

I just openned the 12.2 Camera Frame Buffer EDK project with 12.4 and it worked.
The following were automatically updated by Xilinx Platform Studio (XPS):
- plb_v46 1.04.a => plb_v46 1.05.a
- mpmc 6.01.a => mpmc 6.02.a
- clock_generator 4.00.a => clock_generator 4.01.a
- cpu 1.12.b => cpu 1.13.a
With these automatic updates, I was able to build, and execute the designs on the IVK hardware.
Can you send me your EDK project ?
At a minimum, can you send me the .MHS/.MSS files for your EDK project ?

i am trying to figure out whats the difference of SG_I2C_CONTROLLER from a XPS_IIC ? well except that it is generated from sysgen.
if i do not have matlab and simulink, and would like to use the IVK using EDK/ISE, how is that possible ?

Chee Kin Tang,
As you mentionned, SG_I2C_CONTROLLER is a PCORE generated with System Generator for DSP.
Unless you want to modify it, you don't need SysGen to use this PCORE. You just need EDK.
I have not been able to successfully use the Xilinx XPS_IIC I2C Controller to communicate with the OmniVision OV9715 image sensor.
This is the reason I am using the alternate SG_I2C_CONTROLLER.
You will notice that I have created a software abstraction layer, sw_fmc_iic, on top of these two I2C controllers.

I am working on the issue for a while.
It can communicate with the OV9715, however, it is rather unstable.
Mario, do you have any update on using XPS_IIC with OV9715?
