Using TMS320C6657 EVM but we are facing the following issues:
- Tried to send data from DSP to FPGA - “failed”
- Tried to loopback on communication from DSP – “external loopback failed”
- Received error number 4 on the 4 lanes on DSP
- Have a problem with serial rapid i/o
- Tried to send in MODE-6, no success
- Data rate - 2.6GHz to 1.25GHz
- Data is not being received by DSP
- Tried to calibrate and synchronize the channel, not accessible
- Internal loopback works properly – 2.5GHZ
- External loopback doesn’t work - 2.5GHZ/1.25GHZ
- No compatibility between FPGA and DSP
- The impedance of the board doesn’t match
Please help to resolve this.
