esp_wifi_init() 期间堆内存不足怎么处理？

我正在使用带有 LVGL 的 ESP32 项目。起点是https://github.com/espressif/esp-dev-ki ... ello_world项目。我想添加 WiFi 接入点功能，但似乎没有足够的可用内存。减小 LVGL 的缓冲区大小，或将其移至 PSRAM 可解决该问题。但这使得显示极其缓慢。我打印了 lvgl 分配的数量、可用内存和 largest_free_block 以确定是否应该有足够的可用内存。“largest free”在调用 esp_wifi_init() 之前打印出来。

我不明白为什么没有足够的可用内存...
