Hello,
I am completely new to dsp's and USBi so I am not entirely sure what is going wrong in my set up, but I get a communication failure when trying to program an adau1701. I am using THIS adau1701 mini learning board and THIS USBI JTAG programmer in combination with SigmaStudio to program a pair of DIY speaker according to THIS project on YouTube. I am powering the DSP through the speaker using the 5v pin and gnd pin. I have the USBi connected through the SCL pin and SDA pin, but I have also tried to connect another gnd through the usbi as well. The green LED on the dsp is flashing when powered. After compiling the program on Analog Studio I try to download it to the dsp but get a Communication Failure. I have 2 separate dsp's that exhibit this same behavior. If I try to only hook the dsp's up through the USBi, switching the 5v and the gnd connections to the usbi I still get a communication failure. On the advice that of another forum post, I have confirmed that the SCL and SDA pins are both high when the board is powered, so I don't believe the ports are dead on both of the dsp's. I am not sure if I am on the right route or if I have missed something in the process or set up. Any advice to point me in the right direction is greatly appreciated as I am not entirely sure what to try from here.
