In this step, the TRF1208 and AFE79xx on the TRF1208-AFE7950-EVM is programmed.
- Click on the script named AFE79xx_EVM_Mode1.py and press F5. No errors are expected, but warnings regarding SPI control, relinquish, and reset property can be ignored. This step takes a few minutes.
- Check the Log window to monitor any errors. This step completes the TRF1208-AFE7950-EVM configuration. Current consumption into the TRF1208-AFE7950-EVM is approximately 3 A.
- An LOS error indicates that the SerDes RX is electrically idle, in which case, the TX output will not be normal. This error can be resolved by resending the data (the DAC pattern) and reconfiguring the TRF1208-AFE7950-EVM (that is, run basicbring-up.py again).
- GPIO warnings or sysref errors usually indicate supply voltage or current limitations. Verify the power supply to the TRF1208-AFE7950-EVM and ensure a 5.5-V supply voltage and a 4-A current limit is used. Restart the Latte UI and rerun the scripts.
