Problems with save_on_shutdown: true on EVK-F9P sensor

[AlboAlby00]

Describe the bug
I'm currently trying to use the save_on_shutdown parameter in order to save the configuration to non-volatile memory.

This is the output I get after stopping the node:
[ublox_gps_node-1] [INFO] [1715607301.948972898] [evk_f9p_rtk_module]: INF: ANTSTATUS=INIT
[ublox_gps_node-1] [INFO] [1715607302.949267428] [evk_f9p_rtk_module]: U-Blox Flash BBR failed to save

[INFO] [ublox_gps_node-1]: process has finished cleanly [pid 174366]

Next time I try to run the node, nothing is being published on the topic /gps/fix and I need to plug out and back in the sensor to make it work again.

I'm connecting to the EVK-F9P through the USB port.

These are the parameters I'm using for the EVK-F9P.

Sending the UBX-UPD-SOS directly from U-center works perfectly.

Does anyone have any theory about what is causing this problem?
