Install and Flashing Instructions

Information on Flashing the FC is mostly collected on the RC Groups Thread, but distributed over hundreds of post. The install instructions in this file consolidate this information.

Windows

See RC Groups Thread First Post for now.

Linux

For flashing on Linux, the OpenOCD toolchain is used. The install instructions have been tested to work with OpenOCD 0.9.0 on Debian-based systems (Ubuntu 14.04).

Install OpenOCD 0.9.0

On some OS versions, older versions of OpenOCD might be the default. On Debian-based systems you can check which version is the default by running

apt-cache policy openocd
  • If the output indicates a version below 0.9.0, you can install it on Debian-based systems (such as Ubuntu 14.04) using these commands:
wget http://lug.mtu.edu/ubuntu/pool/universe/h/hidapi/libhidapi-hidraw0_0.8.0~rc1+git20140201.3a66d4e+dfsg-3_amd64.deb
sudo dpkg -i libhidapi-hidraw0_0.8.0~rc1+git20140201.3a66d4e+dfsg-3_amd64.deb
wget http://ubuntu.mirrors.tds.net/ubuntu/pool/universe/j/jimtcl/libjim0.76_0.76-1_amd64.deb
sudo dpkg -i libjim0.76_0.76-1_amd64.deb
wget http://ubuntu.mirrors.tds.net/ubuntu/pool/universe/o/openocd/openocd_0.9.0-1build1_amd64.deb
sudo dpkg -i openocd_0.9.0-1build1_amd64.deb
  • If the output of the check indicates a version equal or higher to 0.9.0, just install openocd:
sudo apt-get install openocd

Toolchain Install and Build

Run the following to install the necessary build tools:

apt-get install git build-essential gcc-arm-none-eabi libnewlib-arm-none-eabi

Clone the repository:

git clone https://github.com/silver13/h8mini-testing
cd h8mini-testing

Build the firmware:

cd gcc
make

Flashing

Before being able to flash, the board needs to be unlocked. This only has to be performed once for every controller board. See Post 2211 and preceding ones on RCGroups for details.

openocd -s /usr/share/openocd/scripts -f /usr/share/openocd/scripts/interface/stlink-v2.cfg -f /usr/share/openocd/scripts/target/stm32f1x.cfg - debug_level 3 -c init -c "reset halt" -c "mww 0x40022004 0x45670123" -c "mww 0x40022004 0xCDEF89AB" -c "mww 0x40022008 0x45670123" -c "mww 0x40022008 0xCDEF89AB" -c "mww 0x40022010 0x220" -c "mww 0x40022010 0x260" -c "sleep 100" -c "mww 0x40022010 0x230" -c "mwh 0x1ffff800 0x5AA5" -c "sleep 1000" -c "mww 0x40022010 0x2220" -c "sleep 100" -c "mdw 0x40022010" -c "mdw 0x4002201c" -c "mdw 0x1ffff800" -c shutdown

Once the board is unlocked, the firmware can be flashed using

openocd -f /usr/share/openocd/scripts/interface/stlink-v2.cfg -f /usr/share/openocd/scripts/target/stm32f1x.cfg -c init -c "reset halt" -c "flash write_image erase h8mini 0x08000000" -c "verify_image h8mini 0x08000000" -c "reset run" -c shutdown
