Add a new CMake function esp_partition_flash_binary() that provides a
unified API for registering partition data binaries to be flashed. It
replaces the direct esptool_py_flash_target calls scattered across
components (spiffs, fatfs, nvs_flash) with a single function that:
- Resolves partition offset from the partition table automatically
- Determines encryption requirements (auto-detect or ALWAYS_PLAINTEXT)
- Creates per-partition flash targets (e.g. idf.py <partition>-flash)
- Optionally includes the binary in `idf.py flash` via FLASH_IN_PROJECT
On the linux target, the function registers binaries for pre-loading
into the emulated flash. A build-time manifest (linux_flash_data.txt)
is generated via file(GENERATE), and partition_linux.c reads it at
runtime to copy each binary into the memory-mapped flash buffer at
the correct offset.
The partition_ops example is updated to use the new function and
includes a custom_partition with pre-built data to demonstrate the
full workflow, including on the linux target.
Add pytest test coverage for cmakev2 build system examples that had
none.
CMakeLists.txt fixes required to enable testing:
conditional_component and plugins: added idf_build_generate_flasher_args()
since these use the low-level build API (idf_build_executable /
idf_flash_binary) which unlike idf_project_default() does not call it
automatically. Without it, flasher_args.json was missing from the build
output and pytest-embedded could not initialize the DUT.
multi_binary: both app1 and app2 were registered in the global flash
target via idf_flash_binary(...FLASH), creating a duplicate key at offset
0x10000 in the flasher_args.json generator expression and preventing the
file from being generated. Fixed by removing FLASH from app2's call so
only app1 is registered in the global flash target. idf_build_generate_flasher_args()
now produces a valid flasher_args.json with app1 as the default app binary.
The test patches the binary path to app2.bin when testing the second app.
The WebSocket echo server tests connect immediately after seeing
"Starting server on port:" in the device log, but URI handlers
(/ws, /ws_partial, /auth) are registered asynchronously after the
server starts, taking 40-660ms depending on config and CI load.
This causes two failures:
1. WebSocket handshake returns 404 Not Found because the URI
handler is not registered yet when the client connects.
2. WebSocket echo returns wrong data because the server is in a
partially initialized state.
Wait for "Returned from app_main()" before connecting, which
guarantees all URI handlers are registered. Add connection retry
with WebSocketBadStatusException handling to WsClient and to the
partial frame test's raw websocket connection.
Extract _wait_for_server_ready() helper to deduplicate the WiFi
credential input and server readiness logic across all 3 tests.
Replace erase_nvs + SNTP time sync with direct NVS timestamp injection
from the pytest host. This eliminates CI flakiness caused by NTP servers
being unreachable from the CI lab network.
Changes:
- Add write_time_to_nvs() helper that generates an NVS partition image
with the current host timestamp and flashes it to the DUT before each
test. The firmware reads this via the existing update_time_from_nvs()
path and skips SNTP entirely.
- Remove @pytest.mark.parametrize('erase_nvs', ['y']) from all 4
Ethernet-based tests since NVS is now written with valid data.
fix(examples): replace unreliable external URL in https_x509_bundle example

Add ESP32-S31 USB DWC/UTMI LL headers, SoC register structures, peripheral
descriptors, capabilities, and linker mappings so the HS OTG controller and
UTMI PHY can be built in esp_hal_usb.
Introduce SOC_USB_FSLS_PHY_NUM on USB-OTG targets to separate FSLS USB_WRAP
support from OTG/UTMI support. Use it to gate usb_wrap, the USB PHY driver,
docs, and example build rules on targets without an FSLS PHY.
Also add UTMI data pulldown control to the HAL, clear the boot-time DWC
suspend state on ESP32-S31, alias the legacy internal PHY target to UTMI for
backward compatibility, and extend usb_phy tests for UTMI-only targets.
