274fff4226 Use internal libm for all atmel-samd boards. 2017-10-16 12:20:33 -07:00

dbd3f15168 1. Use lib/libm for small (non-Express builds) to gain back a lot of flash space.
2. Add flag INTERNAL_LIBM to mpconfigboard.mk files to signal using lib/libm.
3. Fix floating-point warnings in lib/libm
4. Turn off -finline-limit, no longer needed due to 1.
5. Add explicit flags for SPI_FLASH_FILESYSTEM and INTERNAL_FLASH_FILESYSTEM
to mpconfigboard.mk files, so they don't need to know the name of the .c file
that implements those. Makefile takes care of checking the flags and including
the right files.

8d0d5defc7 atmel-samd: Use LTO for all builds to get 5000 bytes back on express boards. 2017-04-18 09:44:04 -07:00

062fac1d43 atmel-samd: Use link time optimization to reduce code size of builds which
share space with the file system.

"Express" builds with SPI flash crash the compiler for some reason so its
currently disabled for them.

306c921ed1 atmel-samd: Rework mass storage interaction with underlying block
storage to use micropython's VFS interface.

This makes mass storage work with any VFS implementation rather
than a single one.

343ff4faed atmel-samd: Make the Arduino Zero build use a bootloader. 2016-10-14 13:10:16 -07:00

90bf13efd5 atmel-samd: Correct USB PIDs.
Arduino and Adafruit convention is for user programs to have PIDs
starting with 8 and bootloaders starting with 0.

7e08347d5c atmel-samd: Support composite CDC and mass storage USB device.
Be careful to not use the flash file system while using mass storage
because both pieces of code attempting to change the fs can corrupt it.

8f26d181c3 Blinking the LED works. Clocks should be set up correctly.
Everything works fine without USB being plugged in but faults (I think) when USB is plugged in. This is switched away from the USB code from the bootloader onto the USB code thats generated by Atmel Studio using the high level classes from ASF.
