Hail
 Hail Board The Hail Board uses a ATSAM4LC8BA, which has 512K Flash and 64K SRAM.
To get started on the Mac, see https://github.com/cxbrooks/tock/blob/cxbrooks/hail/mac/boards/hail/README.md Be sure to use the note: /opt/local/lib/gcc/arm-none-eabi/5.1.0/../../../../arm-none-eabi/bin/ld: cannot find crt0.o: No such file or directory Be sure to update your path: export PATH=/usr/local/Cellar/arm-none-eabi-gcc/5-2016-q3-update/bin:${PATH} The Hail uses a USB MicroB connector and typically comes provisioned with the
Hail ExamplesThe user programs are in Mac OS X: To compile and upload an example, plug in the board and then run bash-3.2$ ls -ltr /dev/tty* | tail crw-rw-rw- 1 root wheel 4, 4 Jan 7 10:03 /dev/ttyp4 crw-rw-rw- 1 root wheel 4, 3 Jan 7 10:03 /dev/ttyp3 crw-rw-rw- 1 root wheel 4, 2 Jan 7 10:03 /dev/ttyp2 crw-rw-rw- 1 root wheel 4, 1 Jan 7 10:03 /dev/ttyp1 crw-rw-rw- 1 root wheel 4, 0 Jan 7 10:03 /dev/ttyp0 crw-rw-rw- 1 root wheel 18, 0 Jan 7 10:03 /dev/tty.Bluetooth-Incoming-Port crw-rw-rw- 1 root wheel 18, 2 Jan 7 12:35 /dev/tty.usbserial-00001014 crw--w---- 1 cxh tty 16, 1 Jan 7 12:36 /dev/ttys001 crw-rw-rw- 1 root wheel 2, 0 Jan 7 12:37 /dev/tty crw--w---- 1 cxh tty 16, 0 Jan 7 12:37 /dev/ttys000 bash-3.2$
If the port is not visible, reboot or see Mac OS Missing TTY Port To compile TockOS and upload, run: cd tockos/boards/hail make PORT=/dev/tty.usbserial-00001014 TOCK_BOARD=hail program To install the blink program: cd ../../userland/examples/blink make PORT=/dev/tty.usbserial-00001014 TOCK_BOARD=hail program Hail Read from Stdouttock/userland/examples/c_hello prints to stdout.
