Hi,

I have connected a video decoder extension board and a video encoder extension board to a BF609 EZ-board. Each time i try to run an example find on Analog Device's website, I have some error by example for the "VideoEncoder" example with "ADI_DEBUG" activate on preprocessor, i have this result on the console :

 

Encoder : adi_twi_Write failed

Encoder : adi_twi_Write failed

Encoder : adi_twi_Write failed

All done

 

And with the "FrameCapture_bf609" example, i have this output :

 

HDMI A, Non-blocking mode, UYVY422 video

Decoder Soft Config - adi_twi_Write failed : 14

Decoder Soft Config - adi_twi_Write failed : 14

Decoder Soft Config - adi_twi_Write failed : 14

Decoder Soft Config - adi_twi_Write failed : 14

Failed to set TWI device number to access ADV7842 video decoder, Error Code: 0x00000008

Failed

 

If someone what i am doing wrong, i'll be happy to know.

 

Best regard
