调研方向

首先阅读 counter.py 程序和 urequests 下载路径,然后在调用 counter def 后使用 14k .mpy 下载重现 DEVKIT1 故障。在 def 返回前后以及下载期间测量内存,以确定 counter.py 是否在其计数和状态寄存器之外继续占用 RAM。完成标准是找出被保留的分配,或清楚地记录该行为。

描述

I've got the ulp counter in a 14k .mpy file as a def. If the def is not called everything runs OK so the 14k file size is not a problem. There is in fact plenty of ram because the test I'm running is to download a new version of the 14k .mpy file, so there is at least 14k spare.

However if I call the counter def, urequests crashes with "MemoryError: memory allocation failed, allocating 1792 bytes". This is a problem I've struck before on other boards with different defs. For example on ESP32camera boards I have to deinit the camera after taking a pic in the camera def before using urequests or else a similar memory error from urequests.

I'm a bit worried this time though because I can't just deinit the ulp counter, it needs to keep running during deepsleep. Apart from the slow mem it uses for the count & state registers does the counter.py progrm set aside any ram that wouldn't be clawed back automatically when the counter def returns the count to the .mpy?

PS: unlike my trials with with the ESP camera boards, where any attempt to use urequest would crash, my problem with the ulp counter def on this DEVKIT1 board only occurs when I try to download a 14k file from the server, the other urequest tasks (like uploading the count) are working OK.
