After a complete rewrite and re-hash of the original ideal having had it proove itself, a PCB and tightly integrated yet simple to use firmware is the name of the game.
SPIFlashProgrammer is a small but capable board housing a Texas Instruments Tiva-C series ARM microprocessor, two Flash devices for use in a production environment to allow one board to program up to two different target devices on a production line, and USB for power and connecting to a host machine.
When connected to a host, the USB connectivity and flashprog utility come together to form a sleak programming experience, allowing the tool to be used in a "set and forget" manner for test and debug of bitstreams and firmware.
The firmware targets 25 series memory devices such as the M25P16, W25Q80BV, and AT25SF641.
Building requires a small number of prerequsites and dependencies:
- Meson
- Ninja
- A modern arm-none-eabi GCC such as the GNU ARM Embedded Toolchain or any distro or custom build GCC capable of targeting ARMv7 via C++17
To build the firmware and host software, run
meson build --cross-file=cross-files/arm-none-eabi.meson
ninja -C buildYou may then use the results in-place, or install the host software with ninja -C build install.
Programming the firmware onto a newly minted board can be achived via any JTAG adapter that can talk TI ICDI. We use the awesome Black Magic Probe with the toolchain GDB.
