Ymodem receive buffer dinamic allocation.
As far as I can see we increase the code size, and shift a fixed sized buffer from bss to the maloc arene.
I don't consider this an improvement, but I may be overlooking something.
Which advantages do you see with the changed code?
My target have too small size RAM. I want reduced to data and bss.
It is limited to one usage in a static allocation. But dynamic allocation can use generically.
i feel like this is a much more uncommon usage scenario and is more harmful than good to boards, and one which isnt specific to xyzModem. perhaps we need a general tune config which says "prefer malloc over bss" and this creates a set of helper macros which expand either into malloc calls or nothing (since the storage is already in bss). -mike
