Fixes#348
Add the RTC header path in the SDK to the Arduino build path. Also add
pico_utils to the libpico.a for the datetime_to_str call.
Note that the pico_sdk has a bug in the datetime.h header so you need to
manually bracket the include file as "C":
extern "C" {
#include "pico/util/datetime.h"
}
* update included tinyusb to 1.2.0
move tusb_config.h from core to library for more portability
* pump tinyusb
* update tinyusb to 1.3.0
* try to fix ci warning
Use the 24-bit SYSTICK peripheral, wrapped in logic to extend it to a
full 32 or 64bits. W/o the wrapper, SYSTICK will wrap around in ~100ms.
Adds rp2040.getCycleCount() and rp2040.getCycleCount64()
Clean up the libpico build process as crt0.S from the pico-sdk should
be directly used.
Clean up the keywords file.
GCC 10.2 has a bug which causes Windows to rebuild every library on every
compile, instead of caching the first results.
Upgrade to GCC 10.3 which has this fixed.
Add proper OpenOCD executables for non-Linux x86_64 archs.
Update pico-sdk to 1.1.2
Add methods to block the opposite core while doing flash updates.
Ensure opposite core is stopped in LittleFS and EEPROM while doing
flash updates.
Update documentation with new calls.
The SDK would assert if a flash write/erase happened past the end of the
flash space it was built with. So, 8MB chips would crash when accessing
offset 3MB, for example.
Avoid this by specifying the maximum flash available so the SDK won't
trip.
Fixes#76
Build all 4 different boot_stage2 objects with SPI/2 and SPI/4 options.
Add a menu to the generic board to allow selecting between them.
Use the potato/4 boot2 for the Adafruit Feather until we have a better
version verified.
Fixes#42
Add support for Adafruit Feather RP2040 (8MB). Identified with a unique
USB PID so it displays properly once programmed one time. Moved LED to
pin 13 (per the website docs), but have no board to test.
Add over/underclocking menus, applied at boot. Use at your own risk, as
usual.
Add shims to allocate flash space for a filesystem (but not implemented
yet).
Add a "generic" RP2040 board
