TunerPro with custom binary files.

[Jedediah_Frey]

A few of us across parts of the web are starting to make our own ECMs and Firmware. rusefi.com & diyefi.org are two places. I plan on starting a 3rd separate project targeted towards diesel engines. (The first two are for gasoline engines).

RusEFI and myself plan on using the STM32F4xx MCU with the GCC tool chain.

The GCC linker creates a .ELF file (and .map) and then this is converted into a .hex (Intel Hex format), .bin or .srec file for use with ST-Linkv2 utility that flashes the MCU.

All variables will be know before hand. I'm fairly certain there is a way to get GCC to spit out the memory locations (still looking). What format would be best to use with TunerPro? ELF, BIN, HEX (Intel Hex) or SREC.

I'm really hoping to use TunerPro (or similar program) to allow end users to 'tune' their own flash files without having to recompile the MCU software.

Binary, preferably. TunerPro can import Motorola HEX files, but it's not the preferred route of getting calibration information into the program.
