程序可以正常运行，就是每次启动时提示这个错误，ESP-IDF 5.0.1

是基于哪个示例遇到的问题？

再顶一下，其实跟哪个例程没有关系吧，这种一般是什么问题，会有什么实际的影响吗？

影响了启动速度。

把 Serial flasher config -> Detect flash size when flashing bootloader 取消掉，直接设置你板子的 Flash size。自动检测 flash size 的话，生成二级 bootloader.bin 的时候会把 SHA-256 digest 取消掉，导致 ROM 里的 bootloader 校验不过。

果然是这个原因，谢谢
