Keep synchronous polling bounded so long or infinite UART waits do not stall the AtomVM scheduler indefinitely, and preserve partial read data on timeout or device error. Compile the driver when CONFIG_SERIAL is enabled.

Introduce avm_zephyr with an i2c_hal implementation and atomvmlib-zephyr packaging so I2C examples can dialyze against the Zephyr API.

Configure potentiometer channels for the ESP32 Wokwi targets, exercise the API from the Zephyr test suite, and force pristine local Wokwi builds so embedded Erlang modules cannot become stale.

Keep bus pin routing in devicetree and support optional software chip selects through the GPIO API.\n\nPackage the module in avm_zephyr, select SPI controllers for native_sim and ESP32, and add lifecycle and transaction-validation smoke coverage.

From f24803da95fabc028412a0b093355a4ee6282242 Mon Sep 17 00:00:00 2001 From: Peter M Date: Sat, 11 Jul 2026 13:28:45 +0200 Subject: [PATCH 38/71] Zephyr: add portable retention memory API Expose Zephyr's retention subsystem through an Erlang API for sizing, validity checks, bounded reads and writes, and clearing retained storage. Package the module in avm_zephyr and translate subsystem failures into Erlang errors.\n\nReserve checksummed 256-byte retention areas for ESP32, ESP32-C3, ESP32-S3, QEMU x86_64, and RP2040. Keep normal and test board fragments aligned, add focused QEMU and RP2040 scenarios, and cover retention operations in Wokwi.

Keep application-specific bus wiring and pin assignments in devicetree overlays, and require an explicit default SPI choice instead of falling back to SPI0.

Enable PWM on standard and test board fragments, and cover the API on native_sim with Zephyr's fake PWM driver. Also apply the test app.overlay for the shared ramdisk, split the I2C emulator overlay so it is only used by the I2C suite, and provide FFF globals required by the fake PWM driver.

Avoid substituting a simulator-only mock that would test different behavior from the hardware retention backend. Keep retention runtime coverage on supported ESP targets and RP2040 build verification.

ESP32 boards use the existing storage partition, Pico W carves 24 KiB from flash, and native_sim uses the simulated-flash storage partition.

Persist settings through zephyr:settings_* on Zephyr and esp:nvs_* on ESP32. Default gen_tcp/gen_udp to the otp_socket backend on Zephyr, which has no legacy socket port driver. Fold start_network into the existing ESP32 Wokwi suite as test_wifi_z_devmode so leftover AP sockets cannot starve STA.
