Thanks. I was looking for the one listed below

Is there a firmware version change document available?

Thank you both for the explanation!

Thanks for the info.

Can you estimate the power savings per unit time the clock is disabled versus enabled?

I read in the MicroPython change log for v1.5.2: There is now delayed RTC initialisation with LSI fallback, and DMA support for the SD card. The DMA controllers are turned off if DMA is idle for 100 msec or more, saving power. I'm using PYBv1.0. So, if the board goes into suspend mode for more than ...

I went through the same issues a few weeks back with my application. Very frustrating with no predictability of where the program would crash next. It appears to me that garbage collection does not work well.

I second the vote of more FLASH and RAM on the next version.

and please a more accurate RTC crystal.

Thanks for your responses. I was able to re-code such that I no longer need to create the data1 and data2 list and have not seen the memory issue arise yet. I must be at the very harry edge of memory limitations.

Dave is there a reason why gc.collect() will not work correctly? I have it placed at appropriate locations but still have memory issues.

Is it possible to force garbage collection to occur?
