* Move to Arduino API 10501
Track upstream Arduino API headers
* IPAddress V4/V6 compatiblity restored
* Fix WiFiUDP includes
* String differences in example
* HardwareSerial using exported
The audio output objects all have the same general necessary configuration
calls. Abstract them out to a generic AudioOutputBase interface class that
they will inherit from. Simplifies letting applications use different
output channels.
Should be backwards compatible with existing code.
Semihosting is handy for debugging, so allow the core to use `SerialSemi` as the
::printf port. Add menu item to the IDE to allow selection.
Add RISC-V implementation of semihost call
Adds a menu item to enable onboard profiling. This requires significant
RAM and really only makes sense on devices with PSRAM to store the state.
When the menu item is selected, allocates RAM and tracks function calls and
periodically samples the PC to generate a histogram of application usage.
The onboard gmon.out file can be written over Semihosting or
some other way to transfer to a PC for analysis.
Adds a profiling example with command lines.
Using pico-sdk develop branch, add in support for CYW43-based
WiFi/BT/BLE boards on the RP2350 such as the
SparkFun Thing Plus RP2350 or the Pimoroni Pico Plus 2W.
Fixes#2608
Rolls in dynamic SPI divider #2600
* Support LED digitalWrite on RP2350+CYW
Also move "special GPIO" to 64 since the Pimoroni Pico 2W uses the
RP2350B with 48 GPIOs.
* Enable CYW43_PIN_WL_DYNAMIC in IDE and P.IO
Allows calling `cyw43_set_pins_wl(cyw43_pin_array);` to redefine the
CYW43 hookup in the variant initialization.
The RP2350 boot ROM seems to randomize memory on a HW reset, including
both CPU stacks where we normally stuff the "reset to bootloader" flag.
Update the docs and source to remove rp2040.enableDoubleResetBootloader()
on RP2350-based boards.
Fixes#2606
Remove old pre-release BTStack files from sdkoverrides (were needed for
compound BLE devices, but the latest BTStack now incorporates these
changes).
Fixes#2547
* Workaround PSRAM cache invalid'n by reading flash
Fixes#2537
While waiting for a working direct cache flush routine, try and force the
cache to evict all PSRAM values by reading a bunch of flash addresses (which
share the XIP cache). This hurts performance when PSRAM is not used, but
is required for correctness until we have a working XIP flush.
* Invalidate after cleaning the cache line
gmx from the RPI forums came up with this hack and it seems to work!

33% faster for 4K memcpy using DMAMemcyp example
With this assembly:
CPU: 4835 clock cycles for 4K
DMA: 2169 clock cycles for 4K
Using stock Newlib memcpy:
CPU: 7314 clock cycles for 4K
DMA: 2175 clock cycles for 4K
The flash ROM routines seem to overwrite the QMI configuration we set for
PSRAM, rendering it unreadable after any erase or write or ID command.
Wrap the 4 flash control functions to preserve the QMI state on the
RP2350. On the RP2040, simply pass through the call.
Fixes#2537
* 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
Several Arduino APIs realloc(NULL) which is legal and equivalent to
"malloc()", but the PSRAM logic was placing those malloc calls in PSRAM
and not RAM because "0" < RAM_START.
Ensure the realloc address is non-null and before RAM_START before
using PSRAM.
Pull in Raspberry Pi's custom RP2350 ARM and RISC-V ports for FreeRTOS.
Basic tests run, but stress mutex test is failing in unique and interesting
ways.
* Add simplified switching test catching task swap problem
* Freertosrp2350: use FreeRTOS macros in noInterrupts/interrupts when applicable. (#2456)
* Use FreeRTOS macros in noInterrupts/interrupts when applicable.
* Fixed calling taskEXIT_CRITICAL and taskENTER_CRITICAL

* 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)
SWSerial wasn't even building due to a typo in the header, and SerialPIO
needs to set the OE-invert flag after PIO initialization for transmit.
Fixes#2419
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.
