LM5066I: SPM GUI Not Working

Kyle Mehringer

Part Number: LM5066I

Tool/software:

Hello,

We were trying to launch the SPM_GUI for LM5066I EVM. We got the error shown below. We are wondering what could be the reason for this. The EVM is powered up as we can see the output voltage changing from 0 to 50V. We swap the FTDI dongle connection to J5 (10pin connector) just in case it was connected reversely, but neither direction allows the GUI to start up. Do you have any recommendations?

Thank you,

Kyle

Hello Kunal,

I had them try to uninstall and reinstall the FTDI drivers, but that didn't work. We've tried both PI-commander and SPM_GUI. The USB to serial is detected by the laptop without any issue.

Thank you,

Kyle

I tried two connections from FTDI cable to J5 on evm, 180 degree reverse to each other. Neither connection direction worked

Hi Shen,

Please do not connect the complete white colour ribbon cable to the LM5066i EVM J5 connector. Take 3 female-to-female single-strand wires and connect SDA, SCL, and GND appropriately as per these two above images.
