….memory (#5199)

Hello, I just pushed my proposal to describe the undocumented function. I hope, you'll enjoy it ;-)

Assessment

Q Qwen · medium

The query (issue #17521) reports that the ESP32 RTC.memory documentation incorrectly claims persistence across 'restarts' when it doesn't survive poweron_reset. The candidate (PR #6713) is a documentation PR that adds description for machine.RTC.memory() method, but the actual diff shows changes to ESP32 UART driver and bootloader configuration, not the RTC documentation file. While both items relate to ESP32 RTC documentation, the PR does not appear to address the specific accuracy issue raised in the query about poweron_reset behavior. The PR title mentions documenting RTC.memory but the code changes don't match.

Suggested action

Keep both items open. The query needs a documentation fix addressing the poweron_reset behavior claim, while the PR appears to have unrelated changes that may need investigation.
