I was going about adding more code for a G120 custom board.
I was about to add some more references for things like xml, http, cryptogrophy, etc.
I figured I would check how much memory was left, so added code below to show.
Memory is sectioned for many other things, like RLP, LCD buffer and custom heap. An example, if you create a very large bitmap (more than 720KB), this goes into a different memory section. I think this section (custom heap) was 2MB on G120 but not sure.
You will probably never run out of ram on G120, unless you have many images and even then you have many ways to resolve it. But if you ever did manage to, I would be very curious to see how you did it
