* Adds RISC-V compilation option to the IDE and Platform.IO.
* Build RP2350-RISCV libpico, libbearssl
* Fix RP2350 BearSSL library (was copied from RP2040, now built for M33)
* New GCC 14.2 toolchain is required (12.4 RISC-V support is borked)
* Newlib locking fixed prototypes
* Manually force all runtime init code into RP2350 binaries
* Add RISC-V to CI
* Remove RP2350 BOOT2.S files, binaries (not used)
* Clean up minor GCC 14.x warnings
* Add RP2350-RISCV OTA build, link
* Add RISC-V FreeRTOS files (configuration still not running, but builds)
* Add basic documentation
Newlib built using `-Os` causes things like `memcpy` to be very slow on the
RP2350 because it uses byte-wise operations. On the RP2040 this doesn't
matter because there is a ROM routine we use instead of the library, but on
the Pico 2 it's almost 10x slower than the optimal method.
Update GCC to 12.4
Update Newlib to 4.4.0
Move to -O2 library compilation
New toolchain looks to add ~10K to RP2350 flash usage (less on the RP2040).
* Add support for the extra 16 GPIO pins in the menus and core.
* Clean up Generic RP2350 PSRAM ("none" is valid) and flash (other than 16MB) options.
* Add extra GPIO<->peripheral connections
* Add Pimoroni PGA2350 RP2350B-based board
* Pins 32-47 can be used for PIOPrograms
* Avoid hang when PSRAM fails to initialize
* Move libpico to an RP2350B board for SDK (otherwise the SDK drops all GPIOHI support)
* Migrate RP2040-specific bits to separate dirs
* Add chip to boards.txt, isolate RP2040-specifics
* Add RP2350 boot2, bearssl, and libraries
* Platform.IO adjust to new paths
* Add RPIPICO2 JSON for P.IO
* Add RP2350 to Platform.io
* Update Picotool and OpenOCD for all hosts
* Use picotool to generate UF2s
* Build separate libpico blobs serially
Thanks for the review, @aarturo182 !
* Add RP2350 to CI
* Allow Ethernet/WiFi building for RP2350
* Update Adafruit TinyUSB to latest
* Test skip fix
* Make RP2350 Picotool work. update USB ID
* Fix EEPROM/FS flash locations
RP2350 adds a 4K header sector to the UF2, meaning we have 4K less total
flash to work with. Adjust all constants appropriately on the RP2350.
* Adds ilabs board and PSRAM support. (#2342)
* Adds iLabs boards and basic PSRAM support.
* Make PSRAM come up as part of chip init
Uses SparkFun psram.cpp to set timings on clocks which are defined in the
variant file. Prefix things with RP2350_PSRAM_xxx for sanity.
Users don't need to call anything, PSRAM "just appears". Still need to
add in malloc-type allocation.
* Add board SparkFun ProMicro RP2350
Same pinout as the SparkFun ProMicro RP2040 with 8MB PSRAM and RP2350
* Add TLSF library for use w/PSRAM
Fork of upstream to include add'l C++ warning fixes.
* Add pmalloc/pcalloc to use PSRAM memory
free() and realloc() all look at the pointer passed in and jump to the
appropriate handler. Also takes care of stopping IRQs and taking the
malloc mutex to support multicore and FreeRTOS (when that workd)
* Fix BOOTSEL for RP2350
* Add simple rp2040.idleOtherCore test
* Add Generic RP2350 and clean up PSRAM menus
Commercial boards now only have 1 size PSRAM, no need to have menu for them.
* Add Solder Party RP2350 Stamp boards (#2352)
* Add PSRAM heap info helpers, mutex lock mallinfo
* Add RP2350 docs
* FreeRTOS and OTA unsupported warnings for RP2350
Adds a library to run classic Bluetooth A2DP source (output) audio from
the PicoW. Simple example showing operation and callbacks.
Factor out multiple BT lock/unlock and place in the PicoW variant files.
* Add native Apple ARM silicon M1/M2/M3 support
* Identify Mac ARM in download get.py script
Thanks to the ESP32 `get.py` sources!
* Rebuild M1 w/o using strip
* Aggregated several earlier patches in one to add RP2040-Eins board into the project.
- Moved RP2040-ProMini in alphabetical order position.
- Added board description files for RP2040-Eins.
- Added board header file for RP2040-Eins.
- Adjusted unused pins order of RP2040-ProMini to be the same as in RP2040-Eins.
- Added RP2040-Eins to README.md.
- Renamed board files to use underscores to better fit the existing file naming style.
* Updated README.md
