variants/all: Don't reserve a dedicated mbedTLS heap. by iabdalkader · Pull Request #465 · arduino/ArduinoCore-zephyr

iabdalkader · 2026-04-30T13:39:23Z

This patch makes mbedTLS allocate from the libc heap (calloc/free) instead of a dedicated static pool, saving memory for when it's actually needed.

Tested on Portenta-C33 and Portenta-H7, can still load full ca bundle from FS and connect run TLS examples.

Not sure this is the right way IMO - while it obviously frees a LOT of RAM for general use ( 😍 ), there's a risk of not being able to allocate the big TLS buffers if the heaps gets fragmented with use before the connection is attempted. I fear connections may work at the beginning, then start to fail over time until a reboot is done.

iabdalkader · 2026-06-10T17:43:47Z

there's a risk of not being able to allocate the big TLS buffers if the heaps gets fragmented

This is always a possibility. However, if keep this, we'll always be reserving a large chunk of memory that may never be used. Also, some sketches that don't need networking at all could benefit from this extra memory (for example, LVGL).
I think it's best if we free as much memory as possible, and let the users manage it based on actual use cases, instead removing that option completely by locking the memory.

That all said, I'm fine either way, so I'll let you all decide which way to go.

KurtE · 2026-06-11T00:35:59Z

Half way through between? Like allocate whole TLS heap at startup if something references it?

pennam · 2026-06-16T15:43:01Z

closind in favour of #512

variants/all: Don't reserve a dedicated mbedTLS heap.

0b62dc7

This patch makes mbedTLS allocate from the libc heap (calloc/free) instead of a dedicated static pool, saving memory for when it's actually needed. Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
