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.
* Enable LWIP IGMP, MDNS internal server
* Enable MDNS lookup from LWIP DNS
* Add SimpleMDNS responder, small code and no malloc
* Ensure we copy out lwipopts in make-libpico
Adds a small wrapper around the LWIP-provided MDNS responder application.
Drop-in replacement in many basic cases for LEAmDNS.
For FreeRTOS it is important to not allocate memory on an LWIP callback.
LEAmDNS needs to do this to create response objects, leading to crashes.
Increase LWIP timers by bumping the LWIP_ARP number (as done before).
Replace ArduinoOTA LEAmDNS with SimpleMDNS and update a
HTTPUpdateServer example.
* 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
* 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
* Update to 2.0.0 SDK
* Board type needs to be set before earliest SDK setup
* Platform includes update
* Boot2 files
* Simple compilation issues
* Build and link
* PIO rebuild with version
* Newlib wrapper update
* Force inclusion of runtime_init_* fcns
The linker was dropping all references to the library's included
runtime_init_xxx functions and hence things like the IRQ vector
table and mutexes and alarms weren't properly set up leading to
instant crashes on start up..
Explicitly call out one function from the object file stored in
the .A to force the inclusion of all the functions. May be a better
way, heppy to hear any ideas.
* Fix SPI GPIO calls
* Fix Ethernet GPIO
* Remove SDK warnings
Remove the skipped error messages once the following PR merged:
https://github.com/raspberrypi/pico-sdk/pull/1786
* BTStack moved SBC encode/decode paths
* Platform.IO fixes
* BT No longer has special absolute mouse
* Rebuild and update OTA
* Rebuild BearSSL, too
* Update liker file to latest SDK
* Clean up libpicocmake
* Clean up LWIP/BT library names
Add a "-32K" option to all the IP stack options that doubles the PCB and memory
pools from default. For most use cases this is not necessary, but it could be
helpful in cases where large numbers of TCP clients are connected or high
bandwidth applications.
Fixes#2050
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.
Use -O2 only on the LWIP checksum routine, resulting in a speedup of
around 13% (checksumming only, not entire LWIP stack) for 72 add'l bytes
of flash.
Avoid issues with interrupts and priority inversions and other deadlocks
and use a SW based random generator for LWIP when under FreeRTOS.
This means removing any overrides for sleep_until and the two
get_rand_xx calls from the SDK, making things much saner.
Related to #1883, #1872, and other random FreeRTOS lockups.
* Update to Pico-SDK v1.5
* Hook in pico_rand, use ioctl to set ipv6 allmulti
* Move into PicoSDK LWIP mutex, hack timer sizes
* Utilize much of the PicoSDK infrastructure for WiFi
* Add WiFi::begin(ssid, pass, bssid)
* WiFiMulti to use BSSID, make more robust
WiFiMulti will now be more aggressive and try all matching SSIDs, in order
of RSSI, using the BSSID to identify individual APs in a mesh.
Before, if the highest RSSI AP didn't connect, it would fail immediately.
Now, it will go down the list, ordered by RSSI, to attempt to get a link.
* Add Bluetooth support from Pico-SDK
Able to build and run the HID Keyboard Demo from the Arduino IDE, almost
as-is.
Will probably need to make BT configurable. Enabling BT on a plain WiFi
sketch uses 50KB of flash and 16KB of RAM even if no BT is used.
* Separate picow libs, BT through menus, example
Build normal Pico.a and 4 different options for PicoW IP/BT configuration.
Use IP=>IP/Bluetooth menu to select between options.
* CMakefile rationalization
* Move BT TLV(pairing) out of last 2 flash sectors
The pairing keys for BT are stored at the end of flash by default, but
we use the last sector of flash for EPROM and the penultimate one for
the filesystem. Overwriting those in BT could cause some real exciting
crashes down the line.
Move the store to an app-build specific address using a dummy const
array to allocate space in the application image itself.
* PicoBluetoothHID with BT Mouse, Joystick, Keyboard
Add simple Bluetooth Classic HID helper function and port the existing
USB HID devices to it. Port their examples.
* Protect BT key storage from multicore
* Add short-n-sweet Bluetooth documents
* Add Bluetooth Serial port library
* Turn off BT when the BT libraries exit
SingleFileDisk allows for exporting a file from the onboard LittleFS
filesystem to a PC through an emulated FAT drive when connected. The
PC can open and copy the file, as well as delete it, but the PC has no
access to the main onboard LittleFS and no actual on-flash FAT
structures are used.
This is handy for things like data loggers. They can run connected to
USB power for some time, and then connected to a PC to dowmload the CSV
log recorded.
It's almost 2023, allow LFN (long file names) on the emulated USB disk.
Reduce the disk buffer size to 64 bytes. The buffer is statically
allocated so it's always present, even in non-USB disk mode, meaning
all apps will pay the RAM price for it. 64 bytes is slower to read
but works and saves ~1/2KB of heap for all apps.
Adds a 12K OTA stub 3rd stage bootloader, which reads new firmware
from the LittleFS filesystem and flashes on reboot.
By storing the OTA commands in a file in flash, it is possible to
recover from a power failure during OTA programming. On power
resume, the OTA block will simply re-program from the beginning.
Support cryptographic signed OTA updates, if desired. Includes
host-side signing logic via openssl.
Add PicoOTA library which encapsulates the file format for
the updater, including CRC32 checking.
Add LEAmDNS support to allow Arduino IDE discovery
Add ArduinoOTA class for IDE uploads
Add MD5Builder class
Add Updater class which supports writing and validating
cryptographically signed binaries from any source (http,
Ethernet, WiFi, Serial, etc.)
Add documentation and readmes.
* Apply @oddstr13 multicast patch to cyw43 driver
* Initial work for enabling IPv6
* Allow accessing CYW43 stats when LWIP_SYS_CHECK_MS is not set
* Use cyw43_set_allmulti to allow receiving multicast
* Add tools/libpico/build to gitignore

The send buffers are set to 8 * MSS = ~11.5K. MEM_SIZE is now set to
be larger than that, 16K, in order to help avoid having tcp_write fail
with ENOMEM. The attempt to use a smaller size is still included, which
will allow a tcp_write of up to 16 * 16K = 256K, i.e. all of memory.
Fixes#725
Increases the MEM_SIZE outstanding write buffer to 8K
Allows the ClientContext to attempt to send smaller buffer chunks in the
case where MEM_SIZE won't allow the full tcp_sndbuf() transfer.
Fixes#725
