New features for improved memory usage

Very nice feature, many thanks, the memory saving is huge. Now, how much memory per bytes of code do we need ? My esp8622 says out of memory above 10000 bytes of code.

The discussion on the problem running this feature on ESP8266 is solved here : http://forum.espruino.com/conversations/307523/

It's worth noting that since this post there's also 1v93, with E.setFlags({pretokenise:1}).

While it can't be used with code stored in flash, for the functions stored in RAM it'll make a really big difference

Is there a way to use this feature and send modules "as functions" to flash one by one instead of all at once ?

The reason I ask is because I get an "out of memory" when sending more than 10k of cumulated modules this way, which is appreciably more than before this feature. When I set "upload as function" and "save on send", in the console I see all modules are sent at once in one line of "setBootCode(code)". Is it possible to call setBootCode multiple times without erasing previous code saved in flash?

I already found how to do something similar on esp822 using Flash module and setMemoryArea() in the other available flash areas (see this post :http://forum.espruino.com/conversations/290975/), but not in the area used by setBootCode. That would be useful for the other boards without additional flash memory.

So this is for ESP8266? On ESP8266 512k builds you only have 12KB flash memory anyway, so it wouldn't gain you a lot! You can always just write a bunch of data somewhere else in flash and then just save some bootloader code like eval(E.memoryArea( addr, len ))): http://www.espruino.com/Reference#l_E_memoryArea

At the moment there isn't anything, but you could potentially write to the saved memory area yourself. It's only a two uint32s with 2 lengths in, then the data, then a 'magic byte' at the end:

Potentially E.setBootCode could be modified and the IDE could split data up and write it separately though.

Thanks gordon for the clarification. Yes, I use an ESP8266, I didn't realize it was so little available there. And thanks for the pointer, i will look into reading/writing myself in these areas.
