Re: Custom memory allocator for running Lua on CM4

[RAHUL KUMAR <ryadav.exe@...>]

Right but problem is that system free is not available /restricted and even if it is then it will lead to fragmentation. So i was thinking to manage the memory myself after system malloc. Just wanted to check if there is already allocator available ?

I understand that 'realloc' is unavailable on the custom freertos.

If you want a 'hack' to get it running, you could probably implement the 'realloc' function as a wrapper over 'malloc' and 'free'?

I was thinking to request a bigger chunk of memory in one shot from the system and later custom allocator will keep allocating and free memory chunk from that. 

Looking forward to hear from you guys.
