Creating an absolutely placed, checksum-protected library
Technical Note 71483
5/31/2018 9:14 AM
This Technical Note shows how to create an absolutely placed library (functions and data), that can be integrity-checked using a checksum.
This Technical Note applies to IAR Embedded Workbench for ARM. And it focuses on the Cortex-M core.
The idea is that the library can be separately verified and possibly certified once, and later on used by other applications. The library is compiled and linked in a separate Embedded Workbench project.
The output is one ordinary ELF (or HEX) file, and one output file containing the exported symbols. The symbols are exported using the “isymexport“-tool, described in the C/C++ Development Guide, chapter “The IAR Absolute Symbol Exporter - isymexport”.
See the pdf document Creating an absolutely placed library and the example project Example project (IAR Embedded Workbench for ARM 6.30.7) 2.zip.
