I'm quite sure CFE is supposed to flash new firmware to the backup
partition and then mark it as main one. The old firmware partition becomes a
new backup then.
That means you need to check which partition bootloader used to handle
partitioning properly.
+ partition@200000 {
+ label = "firmware";
+ reg = <0x0200000 0x01D00000>;
+ compatible = "brcm,trx";
+ };
+
+ partition@1F00000 {
+ label = "failsafe";
+ reg = <0x01F00000 0x01D00000>;
+ read-only;
+ };
Here you assume CFE always boots from the first firmware partition.
Unless EA9500 CFE does sth stupid it seems like a 50% - 50% guess.
