Hello,

I have a cyclone III Starter Kit C25F324 and a hsmc quad video Bitec card. I am trying to use your design as a basis to do my own design. I compiled the project under quartusII and built it under niosII. The only modification I did is to remove the fifo in SoPC builder because the VIP did not support the "empty" signal of the avalon streaming interface.

When running it under NIos II, the console keeps displaying :

Error:Audio I2C ack access1

Error:Audio I2C ack access2

Error:Audio I2C ack access3

Do you have an idea how to correct this ?

Thanks,

Myriam
