Mmiscool, I know you won't like me telling you this, any more than I like being the one having to tell you, but I think Alpha 64 may have introduced a serious memory problem. I've triple-checked to make sure before 'annoying' you, but have reproduced the same problems 3 times by reverting back to A63 to check things then re-installing A64 and getting the same problems, so it seems more than just coincidence.
There are 2 major symptoms on A64 that I don't get with A63.
1. I had included a memory guage in my script for trying to track down memory leakage problems that I was getting on A63. So it quickly became evident that every time I RUN the A64 script I had less RAMFREE available than the previous time, until eventually there is so little free ram available that the ESP just reboots itself.
This doesn't happen with A63, the memclear instruction causes each re-RUN to start with the same available free ram.
2. But even before able to RUN the script it obviously needs to be SAVED, and whereas on A63 the 'Saved OK' confirmation window only appeared every alternative SAVE as was previously reported, now in A64 it never returns a 'Saved OK' confirmation and it reboots every time - sometimes rebooting itself multiple times on the trot! - so the script never saves or runs correctly.
Perhaps the best way of reproducing my situation is to load the enclosed script on a 4Mb A63 device.
Just SAVE and RUN. If the SAVE causes a reboot the wait till it reconnects and do another SAVE to get the SAVED OK window without the reboot, else the memory is corrupt. RUN the script and note the max available ram to the right of the meter, then browser back and re-run it again to note the same free ram again. If you do that with A64 you will see it reducing every time.
You can check the script stability on A63 by keep sending it a TOGGLE command via serial or udp - the free mem will drop down initially but then stabilise for multiple toggles. Doing the same on A64 will keep eating up free mem till it reboots.
