Supported Targets Linux

esp_stdio custom I/O (Linux host test)

Linux-only host test for the runtime console-mux registration API in esp_stdio: esp_stdio_register_custom_io() / esp_stdio_unregister_custom_io() for both ESP_STDIO_PRIMARY and ESP_STDIO_AUXILIARY roles. The mux logic is pure C (dispatch through esp_vfs_fs_ops_t function pointers), so a small in-memory mock VFS backend is enough — no MCU peripheral required.

Run

idf.py --preview set-target linux
idf.py build
build/test_esp_stdio_custom_io.elf

Or via pytest:

pytest pytest_esp_stdio_custom_io.py --target linux
