Flare is a small Apache 2.0 Licensed FSBL. It's a non-bricking light weight bootloader designed for high reliability embedded systems.
Flare currently only supports booting U-Boot legacy images.
To build Flare configure providing the board, compiler prefix, path to xsa (if required) and optionally a path to build tools.
./waf configure --tools-path=/opt/work/rtems/6/bin/ --compiler_prefix=arm-rtems6 --board=zynq7000 --xsa=~/mz7010_fmccc_2019_2/hardware/MZ7010_FMCCC_2019_2/MZ7010_FMCCC.xsa
After the build is configured you need to build
./waf
The datasafe is a tool to pass data between Flare and the booted exe. The data is stored in DDR memory so hard resets clear it but is usually maintained during soft resets.
The datasafe format is defined in datasafe.txt. Currently, only one format is
supported.
