Release 4.0.2 - New boards, new chips, RP2040 fixes
Overview
Important update for the Pico RP2040, including a floating point math fix. Lots of new RP2350 boards and updates (including RP2350B).
RP2350B support
- Add RP2350B generic/Pimoroni PGA2350 support (#2433)
All 48 GPIO pins on the RP2350B pin are now available for PIO programs and digital or analog read/write.
New boards
- Add board Pimornoi Tiny2350 (#2426)
- Add board Pimoroni Pico Plus 2 (#2415)
- Add new board: IRIV IO Controller. (#2370)
- Add Motion 2350 Pro (#2372)
RP2350 (Pico 2) specific updates
- Fix P.IO MHZ for RP2350, fix RP2350 generic menus (#2366)
- Fix F_CPU 125MHz setting on RP2350 (#2436)
- Document E9 non-workaround (#2444)
- Warn when using PSRAM on non-PSRAM boards (#2441)
- Update P.IO board definition for PSRAM (#2387)
- Add SHA256 SDK libs/inclues for RP2350 (#2364)
- Fix Platform.IO ARDUINO_ARCH_xxx define (#2361)
RP2040 (Pico) specific updates
- Fix RP2040 FP calls in ROM (#2411)
The ROM floating point emulation code was not being linked in to builds after the 2.0.0 SDK release. Applications doing floating point math would end up with apanicon simple additions. This re-enables the ROM-based FP emulation code.
Pico-Debug removed
- Remove even more pico-debug stragglers (#2425)
- Remove straggler pico-debug references (#2422)
- Remove pico-debug because it's archived (#2392)
Pico-Debug is no longer actively supported in the OpenOCD we use, so remove all references. Users will need to use a standalone Debugprobe instead
FreeRTOS
- Allow reconfiguring individual FreeRTOS config items - fixes #2398 (#2407)
- Allow configuring maxIRQs (#2401)
Peripherals
- Ensure sample alignment on PWMAudio example (#2437)
- libraries/PDM/src/rp2040/pdm.pio.h: pio_gpio_init data in pin. (#2432)
- Fix SoftwareSerial/SerialPIO inversion and build (#2423)
- Add TwoWire::writeReadAsync (#2388)
- Expand documentation to clarify pin notation and Servo usage (#2326)
- Add serial inversion for UART and SerialPIO (#2395)
Toolchain updates
Release 4.0.1 - Pico 2 (RP2350) Support, SDK 2.0, new boards
Overview
This is a major release with support for the Raspberry Pi Pico 2 (RP2350) using a new SDK 2.0.0. New RP2350-based boards from iLabs, Solder Party, and SparkFun are supported in addition to the Pico 2. The full 512K of RAM and up to 8MB of PSRAM are available for applications to use.
Special thanks to @arturo182 for a great code review that helped get a working RP2350 build even before I had any chips in hand, and to @PontusO, @Architeuthis-Flux, and @gigapod for kindly supplying chips and boards before I could even order them here in the US.
Pico 2 / RP2350
- Add RP2350 support, new boards (#2337)
Support for the Pico 2 in ARM mode has been added. A slightly updated toolchain (new OpenOCD and Picotool to support RP2350) is included. The Pico2 support includes PSRAM as a first-class memory and is explained in the documentation. Everything that worked on the RP2040 should work on the RP2350 except for FreeRTOS (requires use of a private RPi fork of the upstream we use) and OTA (requires me to understand the new bootup sequence better). SPI, I2C, LittleFS, EEPROM, PWMAudio, LWIP-based networking, multicore, SDK USB and TinyUSB, and more have been verified.
New Boards
- Raspberry Pi Pico 2
- Invector Labs Challenger RP2350 BConnect, Invector Labs Challenger RP2350 WiFi/BLE
- SparkFun ProMicro RP2350
- Solder Party RP2350 Stamp, Solder Party RP2350 Stamp XL
New Ethernet Controllers
- W6100 implementation based on W5500 driver (#2346)
Driver for WizNet W6100 added, works the same as other lwip_XXX drivers
New SDK
- Migrate to 2.0.0 SDK (#2336)
Pico SDK 2.0 is required for RP2350 support and includes a new OpenOCD and Picotool.
Filesystems
- Add VFS to enable POSIX file I/O operations (#2333)
FILE-type calls like fopen() and fprintf() can now natively work with LittleFS or SDFS. - BREAKING: Remove FS::info64, make FS::info 64-bit (#2335)
(4.0.1 is minor hotfix to help force the IDE to download the new picotool and openocd)

Release 3.9.2 - OTA hotfix
Overview
OTA hotfix. In 3.9.1 the app would write a LFS-2.6 format filesystem on flash, but the OTA bootloader was only compatible with the original format and so could never actually read any OTA updates. This hotfix rebuilds the OTA bootloader with LFS-2.6 (and original LFS) format support.
Lots of updates, but nothing that should break existing code.
OTA
- Rebuild OTA bootloader for newer LittleFS version (#2199)
- Clean up OTA example references to ESP8266 (#2200)
LittleFS Updates
Big upgrade to LittleFS, to version 2.9.3. This version is backwards compatible with the 2.5.1 we were using but will update the on-flash format after the first mount. The filename limitation of 32 characters has also been removed.
Webserver and other ESP32-borrowed fixes
Lots of patches migrated from the ESP32, with new support for cookies in the HTTP client.
- Allow uploading huge files to WebServer (#2180)
- Small RAM savings (128b) in WebServer (#2178)
- Add Cookies to HTTPClient (#2186)
- Webserver Ignore extra headers in multipart forms (#2184)
- HTTPClient - Fix case sensitivity for header keys (#2185)
- Fix POST form parser edge cases (#2182)
- Fix AdvancedWebServer.ino uptime conversion (#2183)
Bluetooth classic master mode (connect to keyboard/mouse)
- Bluetooth Master HID and musical keyboard example (#2195)
- Split out BluetoothHCI for shared usage (#2194)
BluetoothAudio crash fix and new features
- Add track info support for BT audio sink (#2190)
- Fix crash on audio end from IRQ, refactor A2DP (#2189)
- Allow setting SerialBT advertised name (#2181)
Miscellaneous
LWIP can now be allocated 2x the normal memory for cases where performance demands it. In normal operation this is very unlikely.
