artery's Introduction

Attemp to port ChibiOS to Artery AT32F435/7 chip

AT32F435/437 looks very similas to STM32F4XX chips

To keep compatibility with STM32 drivers I keep STM32_ prefix for all defines

Also I keep STM32 register naming (where possible)

STM32F435 was used as baseline for this port. I did not fix copyrights and comments yet. So don't be confused by STM copyright and other STM32 stuff inside AT32 directories.

Demo projects:

RT-AT32F435-ARTERY144 demo

See ChibiOS/demos/STM32/RT-AT32F435-ARTERY144

Simple application blinking LEDs and executing RT and OSLIB tests on button press.

Outputs over serial port (USART1) at 38400. On Artery AT-START-F435 this USART is connected to debuger. Debugger connected to PC creates ttyACM device and forwards all AT32 output to this tty.

USB_CDC_IAD demo

See ChibiOS/testhal/AT32/AT32F4xx/USB_CDC_IAD

Application inplementing USB device with two ACM ports. OTG1 port is used.

Simple shell is executed on both ACM ports. Few commands are available. Including RT and OSLIB tests. Type 'help' to see some tips.

Known issues:

  • USB device is not recognized when connected through some HUBs.

OpenOCD with Artery support

See openocd for OpenOCD with Artery chip support.

See ChibiOsdemos/STM32/RT-AT32F435-ARTERY144/at32f4x.cfg openocd_artery.sh and gdb.sh as example on how to flash and run.

Current status

Test hangs... LEDs continue to blink...
