Known Issues

Linker issue [VFS/FatFS]: multiple definitions on directory manipulation routines when using std::filesystem namespace. The issue shall be fixed soon. For the meantime, please avoid using std::filesystem or use the patch mentioned here https://github.com/espressif/esp-idf/pull/13736#issuecomment-2102443764. See also https://github.com/espressif/esp-idf/issues/14174
For ESP32-P4, the data in PSRAM will be destroyed during lightsleep.
For ESP32-P4, CPU frequency switching has become slightly slower when the DFS is used.
