Hello all,
I have successfully tested the video in and video out separately,for ppi driver for BF 561Ezkit. Now I want video in-out same time for 561 Ez-kit,using cora A and core B.We have checked the video out for ppi1, it showing that core B is initialized.I have seen in the menuconfig but there was only one core B initialization option.Can we used the both core at same time for video in-out or is it possible that using only one core ,we can do video in-out.Please reply soon.
-Regards

Message: 55309 there is only an example application for loading into core b because you need to write the application that gets loaded

Hello Mike,
Sorry, I am not getting whatever u reply.If we use only one core there is possible that we can do any processing algorithm on the video and out .Because in VDSP core A and core B is used for real time video out .Means u r saying that only application code, if we write.Please reply I am confused about this.
-Thanks

you can do whatever you want in core b. but that's the point ... you have to write all the code.

Hello Pranay,
Could you let me know how you got the ppi0 and ppi1 drivers compiled for the 561? I am trying to accomplish the same thing.

Hello Justin,
First write the code for ppi0 and ppi1 driver. I have given the different major no. 241 and 242 respectively for these two driver.In vendor I register the driver with respective major no and give the name as you want. i have copied the both code in two different file. One in the ppi driver code(ppi0) and another one in the bfin 7179fb code. And during menuconfig select the both driver from respective position.
If you want separate ppi0 and ppi1 then select any one of them.And compile the code using make command.Then after uImage.ext2 file will be created in the image folder.
-Regards
