This repository contains source of tinySA firmware.

General tinySA support questions should be posted here: https://groups.io/g/tinysa/messages

Use github issue list only for firmware bugs and preferrably cross post to: https://groups.io/g/tinysa/messages

UPDATE: Recent gcc version works to build tinySA, no need old version.

Install cross tools and firmware updating tool.

$ brew tap px4/px4
$ brew install gcc-arm-none-eabi-80
$ brew install dfu-util

Download arm cross tools from here.

$ wget https://developer.arm.com/-/media/Files/downloads/gnu-rm/8-2018q4/gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2
$ sudo tar xfj gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2 -C /usr/local
$ PATH=/usr/local/gcc-arm-none-eabi-8-2018-q4-major/bin:$PATH
$ sudo apt install -y dfu-util

Fetch source and submodule.

$ git clone https://github.com/erikkaashoek/tinySA.git
$ cd tinySA
$ git submodule update --init --recursive

Just make in the directory.

$ make

For tinySA Ultra use this command

$ make TARGET="F303"

Using this docker image and without installing arm toolchain, you can build the firmware.

$ cd tinySA
$ docker run -it --rm -v $(PWD):/work edy555/arm-embedded:8.2 make

First, make device enter DFU mode by one of following methods.

• Jumper BOOT0 pin at powering device
• Select menu Config->DFU (needs recent firmware)

Then, flash firmware using dfu-util via USB.

$ dfu-util -d 0483:df11 -a 0 -s 0x08000000:leave -D build/ch.bin

Or simply use make.

$ make flash

There are several numbers of great companion PC tools from third-party.
