Creating checksum-protected library using RX tools

Technical Note 69721



11/29/2013 9:49 AM


This Technical Note shows how to create an absolutely placed library (functions and data), that can be integrity-checked using a checksum.

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 PDF 2.pdf and the zip Example project (IAR Embedded Workbench for RX 2.42.3).zip.
