【已解决】esp32s3进行https-OTA时，出现wifi:m f null，更新失败

[linshc]

使用的IDF为4.4.3，芯片为esp32s3F4R2.在进行https-ota时，进行到esp_https_ota_begin()出现了wifi:m f null的log然后HTTPS OTA Begin失败了！打印出来的DRAM内存为15512，psram为2077745，基本没怎么用到。是由于内存太少导致的吗？应该如何解决呢？以下为日志消息。

RAM 内存剩余太小了，尝试把东西多放点到PSRAM里

[linshc]

确实是ram太少了，我修改了配置sdkconfig,打开了CONFIG_SPIRAM_USE_MALLOC，然后将CONFIG_SPIRAM_MALLOC_ALWAYSINTERNAL改小后。ram的空间变大了，就正常了。
