ESP32_Lyrat 运行http_play_and_save_to_file失败解决-记录贴
编译例程 esp-adf\examples\advanced_examples\http_play_and_save_to_file 中依照readme的介绍修改了下载口和wifi账号及密码，随后编译下载，但程序一直处于失败重启，日志如下：

Rebooting...
在检查日志时发现有一句话很关键：spiram: Expected 4096KiB chip but found 8192KiB chip. Bailing out..，于是再去config里去修改spiram有关参数：将SPI RAM config 由 ESP-PSRAM32 or IS25WP032 更改为 Auto-detect 随后保存再编译，程序完美运行。
