* 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
The RP2350 has a different blob header requirement to identify a working
image. Ensure that header is present in the OTA loader.
Update the PicoOTA examples for the 2350
* 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)
Use real GPIO pad inversion to allow inverted RX, TX, and controls for
the hardware UART and software PIO-emulated serial ports.
Adds ``setInvertTX(bool)`` and ``setInvertRX(bool)`` calls to both ports,
with ``setInvertControl(bool)`` for the HW UARTS.
* 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
* Add VFS to enable POSIX file I/O operations
Enables use of FILE * operations on internal and external storage. fopen,
fclose, fseek, fprintf, fscanf, etc. supported.
* Add FS/File::stat and support POSIX stat/fstat
RP2040::memcpyDMA implements a DMA-controlled memory copy call identical in
function to standard memcpy, but using an onboard DMA engine. For large
memory transfers this can be significantly faster than using the CPU-based
memcpy. Only 4-byte aligned source, destination, and counts are allowed.
If any inputs are not 4-byte aligned, then standard memcpy will occur so
it will behave correctly for any inputs.
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.
Fixes#1730
Uses DMA operations to avoid the need to bit-bang or busy wait for I2C operations
that might be very slow. Optional, adds new API calls to enable. Simple example
included.
Fixes#1192
Uses DMA operations to avoid the need to bit-bang or busy wait for SPI
operations that might be very slow. Optional, adds new API calls to enable.
Simple example included.
* Add FatFS for onboard flash use/sharing of FAT
* Move all to "fatfs" namespace
The FatFS library defines commonly used names like WORD which could conflict
with user code otherwise.
* Restyle
* FTL-based, wear-leveling FatFS with USB export
Allow using FAT filesystem with onboard flash in a safer, wear-leveled
way and to export the onboard flash to the host as a USB drive for easy
data transfer.
* Update documentation
* Fix submodule reference
* Don't spellehcek ChaN FatFS files
* Disable FTL debugging
* More codespell skips
* Move to latest SPIFTL library
* Allow using raw flash instead of FTL
* Remove unneeded static FIL 4k allocation
* Expose FAT FS format configuration options
* Update documentation
* Remove USB partial flash rewrites
* Remove unneeded dups of FatFS sources
Leave the LICENSE.md and README.md to point to upstream.
* Clean up comments
No polling needed and massively reduces latency by using the GPIO interrupt to
signal the Pico to read a received packet. Also drops CPU load when no packets
are incoming.
