4.1.6.4 Program TRF-LSC-AFE7950EVM

In this step, the AFE79xx on the TRF-LSC-AFE7950EVM is programmed.

  1. Click on the script named AFE79xx_EVM_Mode1.py and press F5. No errors are expected; ignore warnings regarding SPI control, relinquish, and reset property. This step takes a few minutes.
  2. Check the Log window to monitor any errors. This step completes the TRF-LSC-AFE7950EVM configuration. Current consumption into the TRF-LSC-AFE7950EVM is approximately 4A.
  3. An LOS error indicates that the SerDes RX is electrically idle, in which case, the TX output is not normal. To resolve this error, resend the data (the DAC pattern) and reconfigure the TRF-LSC-AFE7950EVM (that is, run basicbring-up.py again).
  4. GPIO warnings or SYSREF errors typically indicate supply voltage or current limitations. Verify the power supply to the TRF-LSC-AFE7950EVM, and ensure a 5.5V supply voltage and a 5A current limit are used. Restart the Latte GUI and rerun the scripts.
