I’ve tried loading V3.3.3 a few times, but it stays at V3.2.1 - I’m not sure if the flash failed or if V3.3.3 is simply not supported. Thanks.
apm latest firmware is v3.2.1
is no longer supported
3.2.1 is the last version you can load on APM. It just doesn’t have the memory capacity or processing power for any newer versions.
