Simple Build Info library

Simple Build Info is library that provides easy way to write build info into flash memory. Build info is useful when verifying new application before application update via (custom) bootloader. User must create sBuildInfo section in GCC linker script. Recommendation is to place sBuildInfo section right after vector table.

It is recommended to define build info in main.c and place SBI_USED somewhere in main() so compiler does not remove build info from flash.

Library documentation is available at Documentation/html/index.html. Example applications are available at Examples folder.

Linker script example

SECTIONS
{
  /* The startup code goes first into FLASH */
  .isr_vector :
  {
    . = ALIGN(4);
    KEEP(*(.isr_vector)) /* Startup code */
    . = ALIGN(4);
  } >FLASH

  .sBuildInfo :
  {
    . = ALIGN(4);
    KEEP(*(.sBuildInfo)) /* Build info */
    . = ALIGN(4);
  } >FLASH

  (...)
}
