Problem with "AUTO-SIM" Image switching

Hi,

I have “AUTO-SIM” feature enabled on a rev C MC7455. From time to time image switch fails when sim card is swapped. Application note EM/MC74xx Auto SIM Feature
2174123-1.2 mentions that AUTO-SIM feature “needs Release 16 FW which has bugs addressed”. Which FW does it refer to?

I also tried AUTO-SIM feature on a rev B MC7455 and it does work reliably.

Below is output of at!image? when switch failed.

Dimitri,

Release 16 means firmware 2.20+, its not clear I agree.
