** ChibiOS/RT port for ARM-Cortex-M3 STM32F103 on LeafLabs MapleMini **
|
||
|
|
*****************************************************************************
|
||
|
|
|
||
|
|
** TARGET **
|
||
|
|
|
||
|
|
The demo runs on the MapleMini with the original MapleMini bootloader.
|
||
|
|
|
||
|
|
You can also use this firmware without the original bootloader. To do so,
|
||
|
|
pass USE_MAPLEMINI_BOOTLOADER=0 to make:
|
||
|
|
|
||
|
|
> make USE_MAPLEMINI_BOOTLOADER=0
|
||
|
|
|
||
|
|
** The Demo **
|
||
|
|
|
||
|
|
This demo flashes the board LED using a thread. Also, a simple command shell
|
||
|
|
is activated on virtual serial port via USB-CDC driver.
|
||
|
|
|
||
|
|
** Build Procedure **
|
||
|
|
|
||
|
|
The demo has been tested by using the free arm gcc embedded toolchain.
|
||
|
|
Just modify the TRGT line in the makefile in order to use different GCC ports.
|
||
|
|
|
||
|
|
** Flashing Target Board **
|
||
|
|
|
||
|
|
To flash the firmware to the maplemini, you can use dfu-util. While the MapleMini is connected via USB and
|
||
|
|
still in bootloader mode, just run
|
||
|
|
|
||
|
|
> dfu-util -a1 -d 1eaf:0003 -D build/ch.bin -R
|
||
|
|
|
||
|
|
If you compiled without the bootloader support, you will have to flash via the
|
||
|
|
original serial flashing method or via SWD. For the serial method please see
|
||
|
|
http://static.leaflabs.com/pub/leaflabs/maple-docs/latest/bootloader.html#id7
|
||
|
|
for a howto. there you can also get the official bootloader files.
|
||
|
|
As a quick reference:
|
||
|
|
|
||
|
|
1) connect TTL UART:
|
||
|
|
TX to maple rx1 ("25")
|
||
|
|
RX to tx1 ("26")
|
||
|
|
GND to gnd
|
||
|
|
3.3V to vcc or 5V to vin
|
||
|
|
|
||
|
|
2) hold RESET and BUT buttons, release RESET, then after a sec BUT
|
||
|
|
(this sets the STM32 into serial upload mode)
|
||
|
|
|
||
|
|
3) use stm32loader.py from the link above to upload the firmware
|
||
|
|
> stm32loader.py -p <uart-device> -evw build/ch.bin
|
||
|
|
|
||
|
|
4) reset device
|
