We are a student-run engineering group at Brown University. This project runs on our satellite, EQUiSat, which will launch in March 2018. It uses an Atmel SAMD21J18A chip and Atmel's developer tools. We are open source, bringing space to the people! Contact: Website and e-mail
A lot of documentation should exist on the Google Drive. Ideally, for CubeSat driver API documentation, check out the respective C files for each device - they should hopefully be well-commented.
Building on Windows
- Install Atmel Studio from Atmel's website.
- Open the CubesatFreeRTOS.atsln file from the parent directory
- Build the project in Atmel Studio
Building on Unix-like Systems (Linux, OS X)
- Acquire the
arm-none-eabi-newlibpackages. These provide the standard binutils (ld, objdump, objcopy, etc) along with compiler (gcc) and standard C library files.
- Add the executables from the above step to your PATH. If you installed via package manager, you should be good to go.
- Use the
./makelinuxscript to convert the Atmel Studio Makefile to a Unix-compatible version and build the executables.
Flashing on Windows
- Can run "Debug" from Atmel Studio, or can upload via Atmel Studio
Flashing on Linux/OS X
This is a work in progress. Currently, openOCD seems to be the most viable solution. There is a config file for the SAM DXX boards (boards which use an ARM Cortex-M0+ processor) which may be what we need. Tentatively, the following may work:
openocd -f target/at91samdXX.cfg
Then, in a separate terminal:
telnet localhost 4444
Run the following within telnet:
reset halt flash write_image erase <path to CubesatFreeRTOS.hex> reset run
