Moves to just released GCC 14.3
Moves to full-fat printf/scanf because Newlib no longer supports all the
calls libstdc++ requires with the older, smaller, nano-formatted-io option.
Moves to latest SDK develop branch with important float acceleration fixes
for the RP2350, among other updates.
Moves to latest pioasm, picotool develop branches
* SDK was refactored, update the includes
* Rebuild PicoSDK and BearSSL libs
* Update certs in BSSL validation example
* Don't spell check the certs!
* Updated tools with full fat++ newlib printf/scanf
* Add PIO.h header verification to CI
Ensure all PIO .pio.h headers match the .pio sources in the tree
* Install all tools for Style check
* Clean up mismatched PIO headers
No functional changes, but the PDM pdm.pio file did not init a data pin
while the pdm.pio.h (the one actually used in the core) did. Correct to
match.
* No need for submodules in the style check
* 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
The PIO and state machine were hard wired, so this caused problems if they were not free. The approach used by the Servo library has been adopted so a free PIO and SM are searched.
The DMA_IRQ_0 was grabbed exclusively, but this conflicts with SPI DMA use. The interrupt is now shared, but has been allocated the highest possible priority.
Since the PDM PIO use is receive only, the PIO state machine RX FIFO's can be joined to reduce DMA interrupt load.
