通常情况下,我们尽量不使用IRAM内存,虽然IRAM会比外部Flash性能高,但是容易造成IRAM空间不足。 由于ESP32默认情况下是开启了WIFI、LWIP速度优化的以及libc库放在了内部IRAM等,具体可通过idf.py size-components查看,我们可以在menuconfig中失能这些选项,只能关闭部分,但足以让我们的工程满足日常需求。 根据实际需求可在以下...

烧录了MicroPython固件后的内存占用情况。 The WROOM device has 4 MB of Flash and about 500k of RAM. The Flash memory is used for the firmware and the file system. Most of the RAM is used by the RTOS and MicroPython interpreter itself, such that for the Python Heap 110k of RAM remain. ...

When I activate "optimize for size", I get a message: Guru Meditation Error: Core 0 panic'ed (Cache disabled but cached memory region accessed). (see below). Activating "Debug without optimization", the panic does not occur but the program works fine. What can I do to optimize for si...
target/esp32p4: Fixed memory access; only perform writeback for DCACHE only. target/esp32p4: Set watchpoints on both cores; previously, watchpoints were set only on the active core. target/esp32p4: Avoid writeback/invalidate all cache memory. Do it according to cache line size. ...
