Areas

Items marked with exclamation marks❗❗are priorities for Q1.2024
Items marked with ⏳ are Open.

Architecture / Refactoring

1. Unifying esp-hal into one package (instead of having esp32-hal, esp32-c3-hal,…)
   • RFC: Unify the HAL esp-hal#446 ⏳
2. Unify the low-power peripheral names and rename the RtcCntl driver #872
3. Something needs to be done about the prelude #849

Bare metal

1. IEEE 802.15.4
   • Needs to be tested and we add support for OpenThread
   • Planned release: 0.1.0
2. BLE ✅
   • Bluetooth support for all chips esp-wifi#93 ✅
     • ESP32-H2: H2: Add BLE support #352 ✅
3. Update/triage supporting libraries
4. ESP32-P4 support

CI

1. Set up hardware-in-loop testing #809 ⏳
   • risc-v support for defmt-test #796 ⏳
   • Setting up runners and basic test
   • HW testing for espflash

Documentation

1. ❗Documenting defmt usage with espflash and esp-hal❗
2. Expand no_std training book
3. Documentation - general discussion of plan. #742

espflash

1. 3.0.0 release
   • https://hackmd.io/@esp-rs/SJcARCWk6

Low-power

1. ❗RISC-V ULP❗
   • Implement remaining peripheral drivers: i2c, UART
   • Add interrupt support
2. ❗Light/Deep sleep modes❗
   • Implement support for light-/deep-sleep esp-hal#375 ⏳
     • ESP32-C6 in progress: C6 sleep driver MVP #918
   • Modem sleep

New Chip Support

1. ESP32-P4
   • Preview-support in ESP-IDF v5.2
   • Full support in ESP-IDF v5.3
2. ESP32-C5
   • Supported in ESP-IDF v5.3

Real Time Operating Systems (RTOS)

• Nothing

Research

1. R&D: Investigate using heterogenious lists for ideal resource management workflow#789

STD

1. Support for the Thread protocol
   • Not clear what needs to be done here... ESP IDF already supports the OpenThread C API; seems baremetal is converging towards OpenThread as well
   • There are not good, safe bindings for OpenThread in Rust

Xtensa

1. Upstreaming Rust patches once LLVM patches are in experimental target
   • Tracking Issue for merging to upstream (LLVM-57) espressif/llvm-project#4 ⏳
2. Tooling: lld
3. probe-rs support - dependency of Running tests on real HW (CI area)

Other

• Nothing
