I'm trying to integrate lwip and mbedTLS on a project running on LPC1769 MCU
from NXP. This MCU features 64kB SRAM in two separate banks of 32kB.
I don’t have any particular experience of the lwIP + mbedTLS combination
that you are using and how to tune it but I have recently been working
on a similar sounding project using the LPC1768.
The way that the memory ended up being partitioned was:
16K @ 0x2007C000 (AHBSRAM0) - Ethernet send and receive buffers /
descriptors
16K @ 0x20080000 (AHBSRAM1) - Dedicated memory used for SSL
32K @ 0x10000000 (RAM) - System memory for remaining application
We had to be careful in the memory management to make sure that when
memory was requested dynamically it was allocated from the right pool.
