ADS1298 whit C5515EVM error running ECG demo

Hello,

I followed.strictly this Application Report PDF named TMS320C5515 DSP for ADS1298.pdf. 

I join the EVM5515 whit the ADS1298 and I compile the demo of ECGsystem...

But after loading and running ECGSystem.out, the LCD display the name of the program "ECG MONITOR" but signals via  the channels can't recieve ECGsignals or display it, do you know something about this?

maybe I forgot to move a jumper of the ADS1298 or EVM5515?

can u help?

thanks
