helloworld firmware

Experimental version of Hello world firmware

Written in http://ivorylang.org/

Requires

• stack https://docs.haskellstack.org/en/stable/README/
• arm-none-eabi-newlib
• arm-none-eabi-gcc

Fedora:

dnf install arm-none-eabi-gcc-cs arm-none-eabi-newlib

Building

To build all images:

./standalone-setup.sh # required if you don't have checked out ivory tower and ivory-tower-stm32 repos in .. (recommended)
make

Tests

Blink

Blinks red and blue LEDs on GPIOD14 and GPIOD15

SimpleBlink

Simplified blink application toggling red LED

CANSendRecv

Test application sending packets from CAN1, blinks on received packets.

CAN2UART

Test application for receiving and sending CAN packets controlled by UART

UART

Simple UART console, allows toggling LED with '1' '2' characters

Run make to build all test applications. Specific application can be built with make APP loaded with make APP-load and make APP-run.

To load Blink test application run:

make blink-test-load

to also issue run and start application after loading use:

make blink-test-run

to just run gdb with new binary without loading:

make blink-test-gdb
# issuing 'load' in gdb         == blink-test-load
# running both 'load' and 'run' == blink-test-run

Flashing

Manually with BlackMagic Probe:

arm-none-eabi-gdb --ex 'target extended-remote /dev/ttyACM0' --ex 'monitor swdp_scan' --ex 'attach 1' --ex 'load' build/can2uart-test/image
