OpenMV Feature: RTC.memory()

enhancement

Description

RTC.memory() working for the STM32, MIMXRT, and Alif on the machine module.

Also, standardize the RTC API on these ports. They all implement the machine API in somewhat different ways.

OpenMV Feature: Memory map support

enhancement

Description

This is a first step towards gcalloc'ing memory from specific RAMs. It will also help align OpenMV's fork with upstream even more, as we have custom fixes to DMA buffers and whatnot, that this will replace.

Assessment

Q Qwen · high

The query (Issue #18960) is a feature request to implement RTC.memory() method for STM32, MIMXRT, and Alif ports to provide persistent memory storage via the RTC module. The candidate (Issue #18967) is a feature request for memory map support to allow gcalloc'ing from specific RAM regions, which is a completely different memory management feature. While both involve memory, they address different subsystems (RTC persistent storage vs. garbage collector memory allocation) and have different use cases. The candidate does not resolve or relate to the RTC.memory() functionality requested in the query.

Suggested action

No action needed - these are unrelated feature requests. The query should remain open as a separate feature request for RTC memory functionality.
