Save parameters to flash returns ok but params not stored.

We are using the Model S Small front motor controller board by Damian McGuire. When we change parameters and save to flash the Web UI says they save to flash was successful. When we power cycle the board the "saved" parameters are reverted back to their old values.

I'm assuming this is related to your other post?

No this is a separate issue from can bus connectivity.

When the can bus is working and the Webui is working the above problem exists.

i.e.
Changing parameters has an immediate effect on the board. However after saving the changed parameters to flash and power cycling the webui shows the old parameters and in fact the board contains the old parameters.

From my understanding there are two classes of parameters: one is stored in flash, the other is volatile. Maybe you try to store a volatile parameter. Or does the issue happen for all?

Forgot the obvious: when the inverter is in Run mode it won't save (because it interrupts the control loop). It must be in stop mode. The CAN Ui doesn't report this yet...
