WLC38RX F/W config setup problem

[Wisejet]

I am making a board using your WLC38RX chip.
I had a problem during the experiment. When I applied a load and then disconnected it, the board rebooted.
So I found a solution. When I updated the Rx f/w, the reboot did not occur.
In order to find the parameter that affected it, I manually changed the config settings from the initial state without f/w update to the same as after the f/w update, but the board still rebooted.
I wonder why there is a difference when the Rx registers config settings are the same.
Is there an invisible setting value?

The f/w used is STEVAL-WLC38RX_config_1F46_EPP.memh.

I assume that you use the GUI for FW upgrade and for parameters modifications.

All the parameters are not accessible by the GUI, it may explain why you see a difference.

When you remove suddenly a load from STWLC38 output, you probably trigger some protections, you can check it by reading the interrupts latches in the GUI .

Please contact your local representative to get the latest FWs.

Thanks for the reply. Thanks to you, I realized that not all parameters are configurable in the GUI.

Hi Sir 

The cause of this may be that the previous FW triggered some kind of protection, because RX dropped from heavy load to light load, which easily triggers VRECT OVP protection.
The new configuration file has already solved this problem.

Some configurations are internal and not open to customers.
