STEVAL-ISC004V1 PDO Configuration Not Working

Using the NVM configuration utility for the STEVAL-ISC004V1 seems to program fine

However regardless of what I am writing the to the NVM, the source capabilities on the device dashboard never change and always show 3 PDOs for 5, 9, and 15 volts.

Dear jadczak_slr,

After programming the new PDOs using the GUI, you must :

- Press "Write device NVM" to write the new parameters inside the STUSB4710 Flash memory

- Reset the STSUB4710 by removing the power supply from the STEVAL-ISC004V1 so that the new parameters are taken into account at next negotiation with the SINK.

After the reset and before connecting a SINK, you can also Read the Device NVM to check that the new parameters have been correctly written.

Best regards,

Didier
