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. -Andy. |
